THS4221D

Texas Instruments · Operational Amplifier · SOIC-8

THS4221D from Texas Instruments, in a SOIC-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 NC unconnected No internal connection; leave unconnected.
2 IN− input Inverting input of the amplifier; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V.
3 IN+ input Non-inverting input of the amplifier; the input common-mode voltage range is VS− + 1.1 V to VS+ − 1.1 V.
4 VS− power_in Negative power supply; supply is 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply, with absolute maximum supply voltage of 16.5 V.
5 NC unconnected No internal connection; leave unconnected.
6 VOUT output Amplifier output; output current is rated at 100 mA (absolute maximum), with rail-to-rail swing of ±4.8 V at RL = 2 kΩ.
7 VS+ power_in Positive power supply; supply is 2.7 V to 15 V single-supply or ±1.35 V to ±7.5 V dual-supply, with absolute maximum supply voltage of 16.5 V.
8 NC unconnected No internal connection; leave unconnected.
