tlc27m2, tlc27m2a, tlc27m2b, tlc27m7 lincmos ? precision dual operational amplifiers slos051c october 1987 revised may 1999 2 post office box 655303 ? dallas, texas 75265 description the tlc27m2 and tlc27m7 dual operational amplifiers combine a wide range of input offset voltage grades with low offset voltage drift, high input impedance, low noise, and speeds approaching that of general-purpose bipolar devices.these devices use texas instruments silicon-gate lincmos technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes. the extremely high input impedance, low bias currents, and high slew rates make these cost-effective devices ideal for applications which have previously been reserved for general-purpose bipolar products,but with only a fraction of the power consumption. four offset voltage grades are available (c-suffix and i-suffix types), ranging from the low-cost tlc27m2 (10 mv) to the high-precision tlc27m7 (500 m v). these advantages, in combination with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs. in general, many features associated with bipolar technology are available on lincmos ? operational amplifiers, without the power penalties of bipolar technology. general applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the tlc27m2 and tlc27m7. the devices also exhibit low voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications. the common-mode input voltage range includes the negative rail. a wide range of packaging options is available, including small-outline and chip-carrier versions for high-density system applications. the device inputs and outputs are designed to withstand 100-ma surge currents without sustaining latch-up. the tlc27m2 and tlc27m7 incorporate internal esd-protection circuits that prevent functional failures at voltages up to 2000 v as tested under mil-std-883c, method 3015.2; however, care should be exercised in handling these devices as exposure to esd may result in the degradation of the device parametric performance. the c-suffix devices are characterized for operation from 0 c to 70 c. the i-suffix devices are characterized for operation from 40 c to 85 c. the m-suffix devices are characterized for operation over the full military temperature range of 55 c to 125 c.

tlc27m2, tlc27m2a, tlc27m2b, tlc27m7 lincmos ? precision dual operational amplifiers slos051c october 1987 revised may 1999 15 post office box 655303 ? dallas, texas 75265 parameter measurement information input bias current because of the high input impedance of the tlc27m2 and tlc27m7 operational amplifiers, attempts to measure the input bias current can result in erroneous readings. the bias current at normal room ambient temperature is typically less than 1 pa, a value that is easily exceeded by leakages on the test socket. two suggestions are offered to avoid erroneous measurements: 1. isolate the device from other potential leakage sources. use a grounded shield around and between the device inputs (see figure 4). leakages that would otherwise flow to the inputs are shunted away. 2. compensate for the leakage of the test socket by actually performing an input bias current test (using a picoammeter) with no device in the test socket. the actual input bias current can then be calculated by subtracting the open-socket leakage readings from the readings obtained with a device in the test socket. one word of cautionemany automatic testers as well as some bench-top operational amplifier testers use the servo-loop technique with a resistor in series with the device input to measure the input bias current (the voltage drop across the series resistor is measured and the bias current is calculated). this method requires that a device be inserted into the test socket to obtain a correct reading; therefore, an open-socket reading is not feasible using this method. v = v ic 4 1 5 8 85 figure 4. isolation metal around device inputs (jg and p packages) low-level output voltage to obtain low-supply-voltage operation, some compromise was necessary in the input stage. this compromise results in the device low-level output being dependent on both the common-mode input voltage level as well as the differential input voltage level. when attempting to correlate low-level output readings with those quoted in the electrical specifications, these two conditions should be observed. if conditions other than these are to be used, please refer to figures 14 through 19 in the typical characteristics of this data sheet.
