OPA4353UA from Texas Instruments, in a SOIC-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 | Output of amplifier A, rail-to-rail output swinging within 10mV of the supply rails with a 10kΩ load. |
| 2 | -In A | input | Inverting input of amplifier A; diode-clamped to supply rails, current-limit to 10mA if signals swing more than 0.3V beyond the rails. |
| 3 | +In A | input | Non-inverting input of amplifier A; rail-to-rail input with common-mode range extending 0.1V beyond the supplies, diode-clamped, limit to 10mA beyond 0.3V. |
| 4 | V+ | power_in | Positive supply, operating range 2.7V to 5.5V (absolute maximum supply 5.5V), minimum operating voltage 2.5V. |
| 5 | +In B | input | Non-inverting input of amplifier B; rail-to-rail input, diode-clamped to the supply rails. |
| 6 | -In B | input | Inverting input of amplifier B; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails. |
| 7 | Out B | output | Output of amplifier B, rail-to-rail output with ±40mA output current and ±80mA short-circuit current. |
| 8 | Out C | output | Output of amplifier C, rail-to-rail output with ±40mA output current and ±80mA short-circuit current. |
| 9 | -In C | input | Inverting input of amplifier C; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails. |
| 10 | +In C | input | Non-inverting input of amplifier C; rail-to-rail input, diode-clamped to the supply rails. |
| 11 | V- | power_in | Negative supply or ground in single-supply operation; input and output signals are referenced to this rail. |
| 12 | +In D | input | Non-inverting input of amplifier D; rail-to-rail input, diode-clamped to the supply rails. |
| 13 | -In D | input | Inverting input of amplifier D; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails. |
| 14 | Out D | output | Output of amplifier D, rail-to-rail output with ±40mA output current and ±80mA short-circuit current. |
