INA826AID from Texas Instruments, in a SOIC-8. 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 | -IN | input | Negative (inverting) differential signal input with input common-mode range from V- to (V+) - 1 V and overvoltage protection up to ±40 V. |
| 2 | RG | passive | Gain-setting resistor connection point 1; external resistor connected between pins 2 and 3 sets gain according to G = 1 + 49.4 kΩ/RG for gains from 1 to 1000 V/V. |
| 3 | RG | passive | Gain-setting resistor connection point 2; external resistor connected between pins 2 and 3 sets gain according to G = 1 + 49.4 kΩ/RG for gains from 1 to 1000 V/V. |
| 4 | +IN | input | Positive (noninverting) differential signal input with input common-mode range from V- to (V+) - 1 V and overvoltage protection up to ±40 V. |
| 5 | -VS | power_in | Negative supply voltage with range ±1.5 V to ±18 V (dual supply) or 3 V to 36 V (single supply); internally connected to exposed thermal pad on underside. |
| 6 | REF | input | Reference input with 100 kΩ input impedance and 1 V/V gain to output; must be driven by low-impedance source (<5 Ω recommended) to maintain minimum 100 dB CMRR at G = 10. |
| 7 | VOUT | output | Rail-to-rail output with voltage swing from (V-) + 0.1 V to (V+) - 0.15 V; capable of driving 10 kΩ load and sourcing/sinking ±16 mA continuous to VS/2. |
| 8 | +VS | power_in | Positive supply voltage with range ±1.5 V to ±18 V (dual supply) or 3 V to 36 V (single supply). |
