OPA4313IPWR 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 | OUT A | output | Channel A output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and the datasheet specifies a short-circuit current of ±15 mA at VS=5.5 V. |
| 2 | -IN A | input | Channel A inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, and input current should be limited to 10 mA when the input is driven beyond a supply rail by more than 0.5 V. |
| 3 | +IN A | input | Channel A non-inverting input has a common-mode range that extends about 200 mV beyond both supply rails, with CMRR, PSRR, offset and THD possibly degrading in the crossover region near (V+)-1.3 V. |
| 4 | V+ | power_in | Positive supply, rated 1.8 V to 5.5 V (±0.9 V to ±2.75 V), and the datasheet recommends bypassing it with a 0.01 µF ceramic capacitor. |
| 5 | +IN B | input | Channel B non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails. |
| 6 | -IN B | input | Channel B inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail. |
| 7 | OUT B | output | Channel B output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V. |
| 8 | OUT C | output | Channel C output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V. |
| 9 | -IN C | input | Channel C inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail. |
| 10 | +IN C | input | Channel C non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails. |
| 11 | V- | power_in | Negative supply rail, used as ground in single-supply operation, to which all input and output voltage limits are referenced. |
| 12 | +IN D | input | Channel D non-inverting input has the same rail-to-rail common-mode range as the other channels, extending about 200 mV beyond both supply rails. |
| 13 | -IN D | input | Channel D inverting input must stay within (V-)-0.5 V to (V+)+0.5 V, with input current limited to 10 mA when overdriven beyond a supply rail. |
| 14 | OUT D | output | Channel D output is rail-to-rail AB-class, drives loads down to 10 kΩ to V+ or ground, and is short-circuit-limited to ±15 mA at VS=5.5 V. |
