THS4521IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN- | input | Inverting amplifier input of the fully differential amplifier. Input common-mode range extends below the negative supply rail (negative-rail input). |
| 2 | VOCM | input | Output common-mode voltage control input. Sets the DC common-mode level of the differential output; if left floating, an internal resistor divider sets VOCM to mid-supply. |
| 3 | VS+ | power_in | Positive power-supply input. Total supply range VS+ − VS− = 2.5 V to 5.5 V (e.g. ±1.25 V to ±2.75 V split, or 2.5 V to 5.5 V single-supply). |
| 4 | VOUT+ | output | Noninverting amplifier output. Rail-to-rail output stage. |
| 5 | VOUT- | output | Inverting amplifier output. Rail-to-rail output stage. |
| 6 | VS- | power_in | Negative power-supply input. Tie to ground for single-supply operation, or to the negative rail for split-supply operation. Note that VS− is tied together internally on multi-channel devices. |
| 7 | PD | input | Power-down control (active low). PD = logic low puts the device into low-power mode (~20 µA typical); PD = logic high or open enables normal operation. |
| 8 | VIN+ | input | Noninverting amplifier input of the fully differential amplifier. Input common-mode range extends below the negative supply rail. |
