HT1274ARZ

HTCSEMI · Precision Op Amps · SOP-14

HT1274ARZ from HTCSEMI, in a SOP-14. 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, which swings rail-to-rail (about 300 mV typical from the positive rail and 300 mV typical from the negative rail at RLOAD = 10kΩ to VS/2).
2 -In A input Channel A inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
3 +In A input Channel A non-inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
4 +Vs power_in Positive supply rail; the datasheet specifies a supply voltage range of 3 V to 36 V.
5 +In B input Channel B non-inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
6 -In B input Channel B inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
7 Out B output Channel B output, which swings rail-to-rail (about 300 mV typical from each rail at RLOAD = 10kΩ to VS/2).
8 Out C output Channel C output, which swings rail-to-rail (about 300 mV typical from each rail at RLOAD = 10kΩ to VS/2).
9 -In C input Channel C inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
10 +In C input Channel C non-inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
11 -Vs power_in Negative supply rail (V-); the input common-mode range extends to this pin.
12 +In D input Channel D non-inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
13 -In D input Channel D inverting input; the input common-mode range extends to V- and up to (V+) - 1.5 V.
14 Out D output Channel D output, which swings rail-to-rail (about 300 mV typical from each rail at RLOAD = 10kΩ to VS/2).
