OPA1664AIPWR 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 | Output of amplifier A, which swings within (V-)+0.6 V to (V+)-0.6 V at RL = 2 kΩ and is continuously short-circuit protected (short-circuit current ±50 mA, tied to VS/2). |
| 2 | -IN A | input | Inverting input of amplifier A, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 3 | +IN A | input | Non-inverting input of amplifier A, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 4 | V+ | power_in | Positive supply rail; total supply VS = (V+)-(V-) is specified from ±1.5 V to ±18 V or 3 V to 36 V, with an absolute maximum of 40 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 6 | -IN B | input | Inverting input of amplifier B, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 7 | OUT B | output | Output of amplifier B, which swings within (V-)+0.6 V to (V+)-0.6 V at RL = 2 kΩ and is continuously short-circuit protected (short-circuit current ±50 mA, tied to VS/2). |
| 8 | OUT C | output | Output of amplifier C, which swings within (V-)+0.6 V to (V+)-0.6 V at RL = 2 kΩ and is continuously short-circuit protected (short-circuit current ±50 mA, tied to VS/2). |
| 9 | -IN C | input | Inverting input of amplifier C, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 10 | +IN C | input | Non-inverting input of amplifier C, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 11 | V- | power_in | Negative supply rail, the reference for the common-mode and output swing limits; the total supply VS = (V+)-(V-) is 3 V to 36 V (±1.5 V to ±18 V) with an absolute maximum of 40 V. |
| 12 | +IN D | input | Non-inverting input of amplifier D, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 13 | -IN D | input | Inverting input of amplifier D, with common-mode range (V-)+0.5 V to (V+)-1 V and input current limited to ±10 mA when a signal can forward-bias the input clamp diodes. |
| 14 | OUT D | output | Output of amplifier D, which swings within (V-)+0.6 V to (V+)-0.6 V at RL = 2 kΩ and is continuously short-circuit protected (short-circuit current ±50 mA, tied to VS/2). |
