OPA4990IPWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Output of amplifier channel 1; the short-circuit current is specified as ±80 mA. |
| 2 | IN1- | input | Inverting input of amplifier channel 1; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 3 | IN1+ | input | Non-inverting input of amplifier channel 1; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 4 | V+ | power_in | Positive (highest) power supply; the operating supply range is 2.7 V to 40 V (±1.35 V to ±20 V) and the absolute maximum is 42 V. |
| 5 | IN2+ | input | Non-inverting input of amplifier channel 2; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 6 | IN2- | input | Inverting input of amplifier channel 2; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 7 | OUT2 | output | Output of amplifier channel 2; the short-circuit current is specified as ±80 mA. |
| 8 | OUT3 | output | Output of amplifier channel 3; the short-circuit current is specified as ±80 mA. |
| 9 | IN3- | input | Inverting input of amplifier channel 3; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 10 | IN3+ | input | Non-inverting input of amplifier channel 3; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 11 | V- | power_in | Negative (lowest) power supply; the input and output voltage limits are referenced to this pin. |
| 12 | IN4+ | input | Non-inverting input of amplifier channel 4; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 13 | IN4- | input | Inverting input of amplifier channel 4; the recommended input voltage range is (V-) - 0.2 V to (V+) + 0.2 V. |
| 14 | OUT4 | output | Output of amplifier channel 4; the short-circuit current is specified as ±80 mA. |
