THS4531AIDR 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. High-impedance analog input of the fully differential amplifier; input common-mode range extends 0.2 V below VS-. Continuous input current limited to 10 mA (abs max); typical input bias current 200 nA. |
| 2 | VOCM | input | Output common-mode voltage control input. Sets the DC common-mode level of VOUT+ and VOUT-. Leave open (or drive) to set the output common-mode to mid-supply; typically driven from an ADC's reference/VCM output. |
| 3 | VS+ | power_in | Positive supply rail. Single-supply operation 2.7 V to 5.4 V (recommended); split-supply operation up to ±2.7 V. Total supply (VS+) - (VS-) must not exceed 5.5 V. Decouple with a low-ESR ceramic capacitor close to the pin. |
| 4 | VOUT+ | output | Non-inverted amplifier output. Rail-to-rail output stage; continuous output current limited to 50 mA (abs max). Complementary to VOUT-; together they form the differential output pair driving the ADC or downstream stage. |
| 5 | VOUT- | output | Inverted amplifier output. Rail-to-rail output stage; continuous output current limited to 50 mA (abs max). Complementary to VOUT+, forming the differential output pair. |
| 6 | VS- | power_in | Negative supply rail. Tie to ground for single-supply operation, or to a negative rail for split-supply operation. Total supply (VS+) - (VS-) must not exceed 5.5 V. Decouple with a low-ESR ceramic close to the pin. |
| 7 | PD | input | Power-down control input (must be driven; do not leave floating). Logic low = low-power/shutdown mode (typical 0.5 µA supply current); logic high = normal operation. Referenced to the supply rails; see datasheet for VIL/VIH thresholds. |
| 8 | VIN+ | input | Non-inverting amplifier input. High-impedance analog input of the fully differential amplifier; input common-mode range extends 0.2 V below VS-. Continuous input current limited to 10 mA (abs max); typical input bias current 200 nA. |
