COS8554TRB 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 | OUT1 | output | Output of amplifier 1; output voltage range extends to within millivolts of each supply rail. |
| 2 | -IN1 | input | Inverting input of amplifier 1; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 3 | +IN1 | input | Non-inverting input of amplifier 1; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 4 | +Vs | power_in | Positive power supply (1.8V to 5.5V); bypass with a 0.1µF capacitor placed as close to the part as possible. |
| 5 | +IN2 | input | Non-inverting input of amplifier 2; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 6 | -IN2 | input | Inverting input of amplifier 2; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 7 | OUT2 | output | Output of amplifier 2; output voltage range extends to within millivolts of each supply rail. |
| 8 | OUT3 | output | Output of amplifier 3; output voltage range extends to within millivolts of each supply rail. |
| 9 | -IN3 | input | Inverting input of amplifier 3; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 10 | +IN3 | input | Non-inverting input of amplifier 3; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 11 | -Vs | power_in | Negative power supply or ground; if not connected to ground, bypass with a 0.1µF capacitor placed as close to the part as possible. |
| 12 | +IN4 | input | Non-inverting input of amplifier 4; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). |
| 13 | -IN4 | input | Inverting input of amplifier 4; voltage range from -Vs -0.3V to +Vs +0.3V. |
| 14 | OUT4 | output | Output of amplifier 4; output voltage range extends to within millivolts of each supply rail. |
