# TSV522IQ2T

**STMicroelectronics** · Operational Amplifier · DFN-8(2x2)

TSV522IQ2T from STMicroelectronics, in a DFN-8(2x2). 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, which swings within 35 mV of each rail when loaded with 10 kΩ to VCC/2. |
| 2 | IN1- | input | Inverting input of amplifier 1; the input current must not exceed 10 mA, so a series resistor on the input path is advised to limit it. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; the input common-mode range extends from VCC- - 0.1 V to VCC+ + 0.1 V. |
| 4 | VCC- | power_in | Negative supply rail, referenced at 0 V in the datasheet test conditions; the device operates from a 2.7 V to 5.5 V supply between VCC+ and VCC-. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; the input common-mode range extends from VCC- - 0.1 V to VCC+ + 0.1 V. |
| 6 | IN2- | input | Inverting input of amplifier 2; the input current must not exceed 10 mA, so a series resistor on the input path is advised to limit it. |
| 7 | OUT2 | output | Output of amplifier 2, which swings within 35 mV of each rail when loaded with 10 kΩ to VCC/2. |
| 8 | VCC+ | power_in | Positive supply rail, operating from 2.7 V to 5.5 V; a 10 nF decoupling capacitor should be placed as close as possible to this pin. |
