lt1784 1 1784fa typical application description 2.5mhz, over-the-top low power, rail-to-rail input and output op amp in sot-23 the lt ? 1784 is a 2.5mhz op amp available in the small sot-23 package that operates on all single and split supplies with a total voltage of 2.5v to 18v. the ampli? er draws less than 750a of quiescent current and has reverse battery protection, drawing negligible current for reverse supply voltages up to 18v. the input range of the lt1784 includes ground, and a unique feature of this device is its over-the-top ? opera- tion capabilitity with either or both of its inputs above the positive rail. the inputs handle 18v both differential and common mode, independent of supply voltage. the input stage incorporates phase reversal protection to prevent false outputs from occurring even when the inputs are 9v below the negative supply. the lt1784 can drive loads up to 15ma and still maintain rail-to-rail capability. a shutdown feature on the 6-lead version can disable the part, making the output high impedance and reducing quiescent current to 5a. the lt1784 op amp is available in the 5- and 6-lead sot-23 packages. for applications requiring lower power, refer to the lt1782 and lt1783 data sheets. programmable gain, a v = 2, a v = 20, 100khz ampli? er features applications n operates with inputs above v + n rail-to-rail input and output n gain bandwidth product: 2.5mhz n slew rate: 2.1v/s n low input offset voltage: 3.5mv max n high voltage gain: 1000v/mv n single supply input range: 0v to 18v n speci? ed on 3v, 5v and 5v supplies n reverse battery protection to 18v n low power: 750a supply current max n output shutdown on 6-lead version n high output current: 15ma min n operating temperature range: C40c to 85c n low pro? le (1mm) thinsot? package n portable instrumentation n battery-powered systems n sensor conditioning n supply current sensing n mux ampli? ers n 4ma to 20ma transmitters l , lt, ltc, ltm, linear technology, the linear logo and over-the-top are registered trademarks of linear technology corporation. thinsot is a trademark of linear technology corporation. all other trademarks are the property of their respective owners. programmable gain ampli? er frequency response C + lt1782 v cc shdn in out 1784 ta01a v ee r2 9.09k r1 10k r3 1k C + lt1784 v cc v cc a v = 2 a v = 20 shdn v ee () a v = 1+ r1 + r2 r3 () or 1+ r1 r2 + r3 frequency (hz) gain (db) 30 25 20 15 10 5 0 C5 C10 C15 C20 1k 100k 1m 10m 1784 ta01b 10k a v = 20 a v = 2

lt1784 9 1784fa applications information supply voltage the positive supply pin of the lt1784 should be bypassed with a small capacitor (typically 0.1f) within an inch of the pin. when driving heavy loads, and additional 4.7f electrolytic capacitor should be used. when using split supplies the same is true for the negative supply pin. the lt1784 is protected against reverse battery voltages up to 18v. in the event a reverse battery condition occurs the supply current is less than 1na. inputs the lt1784 has two input stages, npn and pnp (see the simpli? ed schematic), resulting in three distinct operating regions as shown in the input bias current vs common mode typical performance characteristic curve. for input voltages about 1v or more below v + , the pnp input stage is active and the input bias current is typically C250na. when the input common mode voltage is within 0.6v of the positive rail, the npn stage is operating and the input bias current is typically 500na. increases in temperature will cause the voltage at which operation switches from the pnp input stage to the npn input stage to move towards v + . the input offset voltage of the npn stage is untrimmed and is typically 3mv. a schottky diode in the collector of the input transistors, along with special geometries for these npn transistors, allow the lt1784 to operate with either or both of its inputs above v + . at about 0.3v above v + , the npn input transis- tors is fully saturated and the input bias current is typically 200a at room temperature. the input offset voltage is typically 3mv when operating above v + . the lt1784 will operate with inputs 18v above v C regardless of v + . the inputs are protected against excursions as much as 10v below v C by an internal 1k resistor in series with each input and a diode from the input to the negative supply. the input stage of the lt1784 incorporates phase reversal protection to prevent the output from phase reversing for inputs up to 9v below v C . there are no clamping diodes between the inputs and the maximum differential input voltage is 18v. output the output of the lt1784 can swing to within 80mv of the positive rail and within 4mv of the negative rail with no load. when monitoring input voltages within 80mv of the positive rail or within 4mv of the negative rail, gain should be taken to keep the output from clipping. the lt1784 can typically sink and source over 25ma at 5v supplies, sourcing current is reduced to 7.5ma at 3v total supplies as noted in the electrical characteristics section. the lt1784 is internally compensated to drive at least 400pf of capacitance under any output loading condi- tions. a 0.22f capacitor in series with a 150 resistor between the output and ground will compensate these ampli? ers for larger capacitive loads, up to 10,000pf at all output currents. distortion there are two main contributors to distortion in op amps: output crossover distortion as the output transitions from sourcing to sinking current, and distortion caused by non- linear common mode rejection. if the op amp is operating inverting, there is no common mode induced distortion. if the op amp is operating in the pnp input stage (input not within 1v of v + ), the cmrr is very good, typically 95db. when the lt1784 switches between input stages, there is signi? cant nonlinearity in the cmrr. lower load resistance increases the output crossover distortion but has no effect on the input stage transition distortion. for lowest distortion, the lt1784 should be operated single supply, with the output always sourcing current and with the input voltage swing between ground and (v + C 1v). see typical performance characteristics curve, total harmonic distortion + noise vs output voltage amplitude. gain the open-loop gain is almost independent of load when the output is sourcing current. this optimizes performance in single supply applications where the load is returned to ground. the typical performance characteric curve open-loop gain for various loads shows the details.
lt1784 10 1784fa applications information shutdown the 6-lead part includes a shutdown feature that disables the part, reducing quiescent current and making the output high impedance. the part can be shut down by bringing the shdn pin 1.2v or more above v C . when shut down, the supply current is less than 1a (v C v out v + ). in normal operation, the shdn pin can be tied to v C or left ? oating. see typical performance characteristics curve, supply current vs shdn pin voltage. typical applications negative recti? er adjustable clamp C + C + lt1784 v in out v C v C v C v + C + lt 1 7 8 4 lt1784 v in v clamp v clamp - ~80mv v out 1784 ta02 10k 10k works well to 100khz works well to 100khz - ~80mv simplified schematic q10 d5 q9 q1 q7 r2 1k r6 1.5k r7 1.5k r3 1k r4 2k r8 0.75k r9 0.75k q8 q5 Cin +in q11 q12 d4 q2 d1 q6 q13 q14 r1 6k r5 2k q4 q15 q19 d3 q3 q16 q18 q22 v + q17 q20 q21 out v C 1784 ss shdn 20a + q23 q24 q25 q26 j1
