HT2274ARZ

HTCSEMI · Operational Amplifier · SOP-14

HT2274ARZ 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 1 output Output of amplifier 1, which swings close to both rails under light load and is short-circuit protected for unlimited duration.
2 IN1(-) input Inverting input of amplifier 1, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
3 IN1(+) input Non-inverting input of amplifier 1, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
4 VCC power_in Positive supply, operating from 1.4 V to 7 V, with an absolute maximum of 8 V.
5 IN2 (+) input Non-inverting input of amplifier 2, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
6 IN2(-) input Inverting input of amplifier 2, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
7 OUT 2 output Output of amplifier 2, which swings close to both rails under light load and is short-circuit protected for unlimited duration.
8 OUT 3 output Output of amplifier 3, which swings close to both rails under light load and is short-circuit protected for unlimited duration.
9 IN3(-) input Inverting input of amplifier 3, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
10 IN3(+) input Non-inverting input of amplifier 3, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
11 GND power_in Negative supply (V-), the 0 V reference used for the electrical characteristics.
12 IN4(+) input Non-inverting input of amplifier 4, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
13 IN4(-) input Inverting input of amplifier 4, with input common-mode range from 0 V to VCC-1.3 V that extends to the negative rail.
14 OUT 4 output Output of amplifier 4, which swings close to both rails under light load and is short-circuit protected for unlimited duration.
