THS4505DR

Texas Instruments · Differential OpAmps · SOIC-8

THS4505DR 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 VIN- input Inverting amplifier input; input common-mode range includes the negative supply rail (-5.7/2.6 V typ at ±5 V), with differential input voltage limited to 4 V.
2 VOCM input Output common-mode voltage control input, biased to midrail by two internal 50-kΩ resistors when floating; decouple with a 0.1-µF or 1-µF capacitor.
3 VS+ power_in Positive power supply: 4.5 V to 15 V single supply or ±5 V to ±7.5 V dual supply, 16.5 V absolute maximum; decouple with 10-µF and 0.1-µF capacitors.
4 VOUT+ output Non-inverting differential output, delivering 130 mA typ differential output current drive into RL = 20 Ω at ±5 V (150 mA absolute maximum output current).
5 VOUT- output Inverting differential output; the differential output swing is ±8 V typ into RL = 1 kΩ at ±5 V.
6 VS- power_in Negative power supply, or ground in single-supply operation; decouple with 10-µF and 0.1-µF capacitors.
7 NC unconnected No internal connection on THS4505 (this pin is the power-down pin on THS4504).
8 VIN+ input Non-inverting amplifier input; input voltage is limited to ±VS (absolute maximum).
