# THS4140IDGNR

**Texas Instruments** · Differential Amplifiers · MSOP-8-EP

THS4140IDGNR from Texas Instruments, in a MSOP-8-EP. 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 | VIN− | power_in | Inverting differential input of the fully differential amplifier; input voltage limited to ±VCC. |
| 2 | VOCM | input | Output common-mode control input; the output common-mode voltage VOC equals VOCM. |
| 3 | VCC+ | power_in | Positive supply; VCC- to VCC+ is rated ±16.5 V maximum, with operation from a 5-V single supply to ±15-V dual supply. |
| 4 | VOUT+ | output | Non-inverting differential output; output current is rated 150 mA maximum. |
| 5 | VOUT− | output | Inverting differential output; output current is rated 150 mA maximum. |
| 6 | VCC− | power_in | Negative supply (ground in single-supply operation); VCC- to VCC+ is rated ±16.5 V maximum. |
| 7 | PD | input | Shutdown (power-down) control input on the THS4140; supply current in shutdown is ICC(SD) = 880 µA. |
| 8 | VIN+ | power_in | Non-inverting differential input of the fully differential amplifier; input voltage limited to ±VCC. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
