CA124, CA224, CA324, LM324, LM2902 S E M I C O N D U C T O R Quad, 1MHz, Operational Amplifiers for Commercial, Industrial, and Military Applications November 1996 Features Description * Operation from Single or Dual Supplies The CA124, CA224, CA324, LM324, and LM2902 consist of four independent, high-gain operational amplifiers on a single monolithic substrate. An on-chip capacitor in each of the amplifiers provides frequency compensation for unity gain. These devices are designed specially to operate from either single or dual supplies, and the differential voltage range is equal to the power-supply voltage. Low power drain and an input common-mode voltage range from 0V to V+ -1.5V (single-supply operation) make these devices suitable for battery operation. * Unity-Gain Bandwidth . . . . . . . . . . . . . . . . . 1MHz (Typ) * DC Voltage Gain . . . . . . . . . . . . . . . . . . . . . 100dB (Typ) * Input Bias Current . . . . . . . . . . . . . . . . . . . . 45nA (Typ) * Input Offset Voltage . . . . . . . . . . . . . . . . . . . . 2mV (Typ) * Input Offset Current - CA224, CA324, LM324, LM2902 . . . . . . . . . . . . 5nA (Typ) - CA124 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3nA (Typ) Ordering Information * Replacement for Industry Types 124, 224, 324 PART NUMBER (BRAND) Applications TEMP.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied NOTES: 1. This input current will only exist when the voltage at any of the input leads is driven negative. This current is due to the collector base junction of the input p-n-p transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral n-p-n parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the amplifiers to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This transistor action is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3V. 2. The maximum output current is approximately 40mA independent of the magnitude of V+. Continuous short circuits at V+ > 15V can cause excessive power dissipation and eventual destruction. Short circuits from the output to V+ can cause overheating and eventual destruction of the device. 3. JA is measured with the component mounted on an evaluation PC board in free air.

Due to the PNP input stage the direction of the input current is out of the IC. No loading change exists on the input lines because the current is essentially constant, independent of the state of the output. 5. The input signal voltage and the input common mode voltage should not be allowed to go negative by more than 0.3V. The positive limit of the common mode voltage range is V+ - 1.5V, but either or both inputs can go to +32V without damage. 6. VO = 1.4V, RS = 0 with V+ from 5V to 30V, and over the full input common mode voltage range (0V to V+ - 1.5V). 3-19 CA124, CA224, CA324, LM324, LM2902 Schematic Diagram (One of Four Operational Amplifiers) V+ 4 TO 2, 3, 4 6A 100 A 4A 5 + 6 - 7 2 Q2 - 2 CCOMP Q3 Q5 Q6 Q4 Q1 INPUTS + 3 Q7 Q10 Q8 12 + 13 - 4 4 Q11 RSC Q9 1 VO 10 + 9 - 8 3 Q13 50A Q12 TO 2, 3, 4 V- 11 Typical Performance Curves TA = 25oC V+ = 30V TA = -40 TA 85oC 0.1F 4 V+ 2 + 100 VI 80 V+/2 500 1 VO 3 OUTPUT VOLTAGE (mV) 120 11 60 40 V+ = 10 TO 15V V+ = 26V 20 - 2 450 50pF VI 400 1 VO + 3 INPUT 350 OUTPUT 300 250 0 10 100 1K 10K 100K FREQUENCY (Hz) 1M 0 10M FIGURE 1.
