INA159AIDGKR from Texas Instruments, in a VSSOP-8. 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 | REF 1 | passive | Reference input 1 of the on-chip two-resistor reference divider, typically grounded or tied to VREF for mid-supply biasing; pin voltage must stay within (V−) − 0.5V to (V+) + 0.5V. |
| 2 | −IN | input | Inverting signal input of the difference amplifier (gain 0.2), rated for ±30V maximum input voltage. |
| 3 | +IN | input | Noninverting signal input of the difference amplifier (gain 0.2), rated for ±30V maximum input voltage. |
| 4 | V− | power_in | Negative supply, or ground in single-supply operation; total supply range is +1.8V to +5.5V. |
| 5 | SENSE | input | Output sense pin of the feedback network, connected to OUT in the typical application; pin voltage must stay within (V−) − 0.5V to (V+) + 0.5V. |
| 6 | OUT | output | Amplifier output with continuous short-circuit protection and ±60mA continuous current limit. |
| 7 | V+ | power_in | Positive supply, operating range +1.8V to +5.5V total supply, with a 0.1µF bypass capacitor placed closely across the supply pins. |
| 8 | REF 2 | passive | Reference input 2 of the on-chip two-resistor reference divider, typically connected to VREF; pin voltage must stay within (V−) − 0.5V to (V+) + 0.5V. |
