OPA818IDRGR

Texas Instruments · Global Sourcing Parts · WSON-8-EP(3x3)

OPA818IDRGR from Texas Instruments, in a WSON-8-EP(3x3). 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 PD input Power-down control; low level enables amplifier, high level disables; internal 1MΩ pull-up allows floating.
2 FB output Feedback resistor connection point; internally connected to OUT through 0.8-1.7Ω metal wiring.
3 IN- input Inverting input with 500MΩ ∥ 0.5pF differential impedance; input voltage range VS- to VS- + 0.25V.
4 IN+ input Non-inverting input with 500MΩ ∥ 0.5pF differential impedance; input voltage range VS+ - 3.6V to VS+ - 3.2V.
5 VS- power_in Negative power supply rail; part of 6V to 13V total supply voltage range.
6 NC unconnected No connection; not electrically connected to the die.
7 OUT output Amplifier output; ±50mA maximum linear drive; output voltage swing VS- + 1.2V to VS+ - 1.2V (typical).
8 VS+ power_in Positive power supply rail; part of 6V to 13V total supply voltage range.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
