Derate above 25 C at the following rates: N package at 11.4 mW/C D package at 8.3 mW/C 2. Short-circuits from the output to VCC+ can cause excessive heating and eventual destruction. The maximum output current is approximately 40 mA, independent of the magnitude of VCC. At values of supply voltage in excess of +15 VDC continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. 3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input bias clamps. In addition, there is also lateral NPN parasitic transistor action on the IC chip. This action can cause the output voltages of the op amps to go to the V+ rail (or to ground for a large overdrive) during the time that the input is driven negative. 2001 Aug 03 3 Philips Semiconductors Product data Low power quad operational amplifier AU2902 DC ELECTRICAL CHARACTERISTICS VCC = 5 V; Tamb = 25 C; unless otherwise specified.

VO 1.4 VDC, RS = 0 with VCC from 5 V to 30 V and over full input common-mode range (0 VDC+ to VCC -1.5 V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is VCC -1.5, but either or both inputs can go to +32 V without damage. 4. Short-circuits from the output to VCC can cause excessive heating and eventual destruction. The maximum output current is approximately 40 mA independent of the magnitude of VCC. At values of supply voltage in excess of +15 VDC, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. 5. Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of coupling increases at higher frequencies. 2001 Aug 03 4 Philips Semiconductors Product data Low power quad operational amplifier AU2902 TYPICAL PERFORMANCE CHARACTERISTICS Output Characteristics Current Sourcing 8 ) V2 --OUTPUT VOLTAGE REFERENCED TO V+ DC (V V+ +V + / 2 + - V2 INPUT - CURRENT (mAdc) 90 80 70 60 50 40 30 20 10 0 -55 -35 15 5 25 45 65 85 105 125 Supply Current 4 SUPPLY CURRENT DRAIN (mAdc) Current Limiting 7 6 5 4 3 2 3 2 IO 1 TA = OC to +125oC TA INDEPENDENT OF V+ TA = +25oC = -55oC 30 40 0 0 10 20 SUPPLY VOLTAGE (VDC) 1 0.001 0.01 0.1 1 10 TEMPERATURE (oC) IO+ -- OUTPUT SOURCE CURRENT (mADC) Voltage Gain 160 VOL -- OUTPUT VOLTAGE (V DC ) 10 Output Characteristics Current Sinking V+ = +5V V+ = +15V VOLTAGE GAIN (dB) V+ = +30V 1 V+ V+ /2 - 0.1 + VO 20 140 120 100 80 60 40 Open-Loop Frequency Response V +10M 0.1F VIN - + VO AVOL -- VOLTAGE GAIN (dB) RL = 20K 120 RL = 2K 80 V+ /2 V+ = 30 Vdc and -55 oC < TA < +125 oC 40 0 0 10 20 30 40 0.01 0.001 TA = +25oC 0 0.01 0.1 1 10 100 1 V+ = 10 to 15 Vdc and -55 oC < TA < +125 oC 10 100 1K 10K 100K 1M 10M SUPPLY VOLTAGE (VDC) IO -- OUTPUT SINK CURRENT (mADC) FREQUENCY (Hz) Large-Signal Frequency Response 20 15VDC 100K VD -- OUTPUT SWING (Vp-p) 15 VIN 10 0.1F 1K - + 7.5VDC VO 2K 15 Input Voltage Range 90 80 +V -- INPUT VOLTAGE ( +V DC ) IN 1B -- INPUT CURRENT (nA ) DC 70 60 50 40 30 20 10 0 0 -55 Input Current VCM = 0 VDC V+ = +30 VDC 10 NEGATIVE V+ = +15 VDC POSITIVE 5 5 V+ = +5 VDC 0 1K 10K 100K 1M 0 5 10 -35 -15 5 25 45 65 85 105 125 FREQUENCY (Hz) V+ or V- -- POWER SUPPLY VOLTAGE (+VDC) TA -- TEMPERATURE (oC) SL00521 Figure 3.
