# COS724TR

**COSINE** · Operational Amplifier · TSSOP-14

COS724TR from COSINE, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT1 | output | Amplifier 1 output. Output voltage range extends to within millivolts of each supply rail (typ 1mV with RL=100kΩ, 8mV with RL=10kΩ). |
| 2 | -IN1 | input | Amplifier 1 inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 3 | +IN1 | input | Amplifier 1 non-inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 4 | +Vs | power_in | Positive power supply, 2.5V to 5.5V (single-supply) or ±1.25V to ±2.75V (dual-supply). Bypass with 0.1µF ceramic close to the pin. |
| 5 | +IN2 | input | Amplifier 2 non-inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 6 | -IN2 | input | Amplifier 2 inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 7 | OUT2 | output | Amplifier 2 output. Output voltage range extends to within millivolts of each supply rail. |
| 8 | OUT3 | output | Amplifier 3 output. Output voltage range extends to within millivolts of each supply rail. |
| 9 | -IN3 | input | Amplifier 3 inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 10 | +IN3 | input | Amplifier 3 non-inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 11 | -Vs | power_in | Negative power supply or ground. If not connected to ground, bypass with 0.1µF close to the pin. |
| 12 | +IN4 | input | Amplifier 4 non-inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 13 | -IN4 | input | Amplifier 4 inverting input. Voltage range: -Vs -0.3V to +Vs +0.3V. |
| 14 | OUT4 | output | Amplifier 4 output. Output voltage range extends to within millivolts of each supply rail. |

## CAD (KiCad official)

- Symbol: `COS724TR`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `cos724tr-etched.step` / `cos724tr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cos724tr.step` / `cos724tr.glb` are the bare package body.
