HT8358VRMZ

HTCSEMI · Operational Amplifier · MSOP-8

HT8358VRMZ from HTCSEMI, 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 OUT A output Channel A output, rail-to-rail; output current is specified at ±50 mA with VS = 5 V.
2 -IN A input Channel A inverting input; input voltage must stay between GND and VS (absolute maximum rating).
3 +IN A input Channel A non-inverting input; input common-mode range is 0 V to VS, with input voltage limited to GND to VS (absolute maximum).
4 V- power_in Negative supply rail (GND for single-supply operation); supply is 2.7 V to 5.5 V single supply, 6 V absolute maximum.
5 +IN B input Channel B non-inverting input; input common-mode range is 0 V to VS, with input voltage limited to GND to VS (absolute maximum).
6 -IN B input Channel B inverting input; input voltage must stay between GND and VS (absolute maximum rating).
7 OUT B output Channel B output, rail-to-rail; output current is specified at ±50 mA with VS = 5 V.
8 V+ power_in Positive supply rail; operates from 2.7 V to 5.5 V single supply, 6 V absolute maximum.
