# OPA2835IDGSR

**Texas Instruments** · Operational Amplifier · VSSOP-10-0.5mm

OPA2835IDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | VOUT1 | output | Amplifier 1 output with 40 mA drive capability and rail-to-rail output voltage range. |
| 2 | VIN1- | input | Amplifier 1 inverting input; accepts input signals from -0.2 V to 3.9 V at 5 V supply with maximum continuous input current of 0.85 mA. |
| 3 | VIN1+ | input | Amplifier 1 noninverting input; accepts input signals from -0.2 V to 3.9 V at 5 V supply with maximum continuous input current of 0.85 mA. |
| 4 | VS- | power_in | Negative power supply input and reference ground; operates with supply voltage range from 2.5 V to 5.5 V. |
| 5 | PD1 | input | Amplifier 1 power-down control; low level enables low-power mode (0.5 µA typical), high level enables normal operation; pin must be driven to a valid logic level. |
| 6 | PD2 | input | Amplifier 2 power-down control; low level enables low-power mode (0.5 µA typical), high level enables normal operation; pin must be driven to a valid logic level. |
| 7 | VIN2+ | input | Amplifier 2 noninverting input; accepts input signals from -0.2 V to 3.9 V at 5 V supply with maximum continuous input current of 0.85 mA. |
| 8 | VIN2- | input | Amplifier 2 inverting input; accepts input signals from -0.2 V to 3.9 V at 5 V supply with maximum continuous input current of 0.85 mA. |
| 9 | VOUT2 | output | Amplifier 2 output with 40 mA drive capability and rail-to-rail output voltage range. |
| 10 | VS+ | power_in | Positive power supply input; operates with supply voltage range from 2.5 V to 5.5 V with quiescent current of 250 µA per channel. |
