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. |
