Pinout

Pin Name Type Function
1 OUT1 output Output of op-amp channel 1. Class-AB output stage delivering symmetrical source/sink currents (~29 mA source, ~37 mA typ sink) into loads down to 600 Ω; output impedance ~37 Ω at 9 MHz.
2 IN1- input Inverting input of op-amp channel 1. High-impedance BJT input (Ri ~175 kΩ, Ci ~12 pF) with typical bias current 250 nA; input voltage must not exceed ±15 V or
3 IN1+ input Non-inverting input of op-amp channel 1. High-impedance BJT input (Ri ~175 kΩ, Ci ~12 pF); common-mode range typically ±13 V to ±14 V on ±15 V supplies.
4 VCC+ power_in Positive supply rail. Accepts ±2.5 V to ±15 V dual supply or up to +36 V single supply; absolute maximum ±18 V or +36 V. Typical total quiescent current 8 mA (10 mA max) for all four amplifiers.
5 IN2+ input Non-inverting input of op-amp channel 2. High-impedance BJT input (Ri ~175 kΩ, Ci ~12 pF); common-mode range typically ±13 V to ±14 V on ±15 V supplies.
6 IN2- input Inverting input of op-amp channel 2. High-impedance BJT input with typical bias current 250 nA; input voltage must not exceed ±15 V or
7 OUT2 output Output of op-amp channel 2. Class-AB output stage, short-circuit protected with infinite short-circuit duration (subject to junction temperature limits).
8 OUT3 output Output of op-amp channel 3. Class-AB output stage delivering large symmetric swing (+14.3 V / -14.6 V typ into 10 kΩ).
9 IN3- input Inverting input of op-amp channel 3. High-impedance BJT input (Ri ~175 kΩ, Ci ~12 pF).
10 IN3+ input Non-inverting input of op-amp channel 3. High-impedance BJT input; common-mode range ±13 V to ±14 V on ±15 V supplies.
11 VCC- power_in Negative supply rail. Typically −15 V in dual-supply operation or GND in single-supply operation; absolute maximum −18 V (or 0 V for +36 V single-supply use).
12 IN4+ input Non-inverting input of op-amp channel 4. High-impedance BJT input; common-mode range ±13 V to ±14 V on ±15 V supplies.
13 IN4- input Inverting input of op-amp channel 4. High-impedance BJT input (Ri ~175 kΩ, Ci ~12 pF).
14 OUT4 output Output of op-amp channel 4. Class-AB output stage with excellent channel-to-channel isolation (120 dB channel separation, 20 Hz-20 kHz).
