THS4121IDGKR from Texas Instruments, in a MSOP-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 | VIN− | power_in | Inverting differential input of the THS4121 fully differential amplifier, with the feedback network setting the gain (A = Rf/Rg). |
| 2 | VOCM | input | Output common-mode voltage input that sets the common-mode level of the differential outputs; VOCM symmetry must be maintained for proper operation. |
| 3 | VDD | power_in | Positive supply pin; the datasheet specifies VDD = 3.3 V operation and an absolute maximum supply of 3.6 V (GND to VDD). |
| 4 | VOUT+ | output | Non-inverting differential output; for capacitive loads above 10 pF, a series output resistor of at least 20 Ω is recommended. |
| 5 | VOUT− | output | Inverting differential output; for capacitive loads above 10 pF, a series output resistor of at least 20 Ω is recommended. |
| 6 | GND | power_in | Ground reference pin for the amplifier supply (supply is specified as GND to VDD). |
| 7 | NC | unconnected | No internal connection on the THS4121; leave unconnected (the THS4120 uses this position for PD, which is not present on the THS4121). |
| 8 | VIN+ | power_in | Non-inverting differential input of the THS4121 fully differential amplifier, with the feedback network setting the gain (A = Rf/Rg). |
