COS4177TR
COSINE · Operational Amplifier · TSSOP-14
COS4177TR from COSINE, in a TSSOP-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 | OUTA | output | Output of amplifier A, whose voltage range extends to within millivolts of each supply rail. |
| 2 | -INA | input | Inverting input of amplifier A; voltage range can go from -Vs to +Vs. |
| 3 | +INA | input | Non-inverting input of amplifier A; same voltage range as the inverting input (-Vs to +Vs). |
| 4 | +Vs | power_in | Positive power supply (+5V to +36V single or up to +18V dual); bypass with 0.1µF capacitor placed close to the pin. |
| 5 | +INB | input | Non-inverting input of amplifier B; voltage range -Vs to +Vs. |
| 6 | -INB | input | Inverting input of amplifier B; voltage range can go from -Vs to +Vs. |
| 7 | OUTB | output | Output of amplifier B, whose voltage range extends to within millivolts of each supply rail. |
| 8 | OUTC | output | Output of amplifier C, whose voltage range extends to within millivolts of each supply rail. |
| 9 | -INC | input | Inverting input of amplifier C; voltage range can go from -Vs to +Vs. |
| 10 | +INC | input | Non-inverting input of amplifier C; voltage range -Vs to +Vs. |
| 11 | -Vs | power_in | Negative power supply or ground; if not grounded, bypass with 0.1µF capacitor placed close to the pin. |
| 12 | +IND | input | Non-inverting input of amplifier D; voltage range -Vs to +Vs. |
| 13 | -IND | input | Inverting input of amplifier D; voltage range can go from -Vs to +Vs. |
| 14 | OUTD | output | Output of amplifier D, whose voltage range extends to within millivolts of each supply rail. |
