# INA826AIDRGR

**Texas Instruments** · Instrumentation Amplifiers · WSON-8-EP(3x3)

INA826AIDRGR from Texas Instruments, in a WSON-8-EP(3x3). 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 | -IN | input | Negative (inverting) input with input protection up to ±40 V beyond supply rails. |
| 2 | RG | passive | Gain setting pin; place external resistor between pins 2 and 3 to set gain from 1 to 1000. |
| 3 | RG | passive | Gain setting pin; place external resistor between pins 2 and 3 to set gain from 1 to 1000. |
| 4 | +IN | input | Positive (noninverting) input with input protection up to ±40 V beyond supply rails. |
| 5 | -VS | power_in | Negative supply rail; voltage range ±1.5 V to ±18 V in dual-supply mode or ground in single-supply mode. |
| 6 | REF | input | Reference input; must be driven by low impedance source. |
| 7 | VOUT | output | Rail-to-rail output capable of swinging from near negative supply to near positive supply. |
| 8 | +VS | power_in | Positive supply rail; voltage range 3 V to 36 V in single-supply mode or ±1.5 V to ±18 V in dual-supply mode. |
| 9 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
