MC33079DT from STMicroelectronics, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
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). |
