OPA1637DGKR from Texas Instruments, in a VSSOP-8. 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 | IN- | input | Inverting amplifier input; input voltage must be within VVS- - 0.5 V to VVS+ + 0.5 V, differential voltage ±0.5 V maximum with IN+, input current ±10 mA maximum. |
| 2 | VOCM | input | Output common-mode voltage control input; voltage range from VVS- + 1 V to VVS+ - 1 V (at ±2.5 V supply) or VVS- + 2 V to VVS+ - 2 V (at ±18 V supply). |
| 3 | VS+ | power_in | Positive power-supply input; supply voltage 3 V to 36 V single-supply or ±1.5 V to ±18 V dual-supply mode. |
| 4 | OUT+ | output | Noninverting amplifier output; output voltage swing limited to within ±100 mV of supply rails at ±2.5 V supply or ±230 mV at ±18 V supply. |
| 5 | OUT- | output | Inverting amplifier output; output voltage swing limited to within ±100 mV of supply rails at ±2.5 V supply or ±230 mV at ±18 V supply. |
| 6 | VS- | power_in | Negative power-supply input; supply voltage ±1.5 V to ±18 V in dual-supply mode. |
| 7 | PD | input | Power-down control input; logic low (< VVS+ - 2.0 V) enables power-down mode with 10 to 20 µA quiescent current, logic high (≥ VVS+ - 0.5 V) enables normal operation; leave floating if not used. |
| 8 | IN+ | input | Noninverting amplifier input; input voltage must be within VVS- - 0.5 V to VVS+ + 0.5 V, differential voltage ±0.5 V maximum with IN-, input current ±10 mA maximum. |
