# INA296A2IDDFR

**Texas Instruments** · Current Sense Amplifiers · TSOT-23-8

INA296A2IDDFR from Texas Instruments, in a TSOT-23-8. 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 | IN- | input | Current-sense amplifier negative input; for high-side applications connect to the load side of the sense resistor, and for low-side applications connect to the ground side of the sense resistor. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | REF2 | input | Reference 2 voltage input, to be connected to a potential from 0 V to VS to set the output level. |
| 4 | NC | unconnected | Reserved pin that must be connected to ground. |
| 5 | OUT | output | Output voltage of the amplifier, which can range from as low as 20 mV to as high as 200 mV below the supply voltage. |
| 6 | VS | power_in | Power supply input, operating from 2.7 V to 20 V. |
| 7 | REF1 | input | Reference 1 voltage input, to be connected to a potential from 0 V to VS to set the output level. |
| 8 | IN+ | input | Current-sense amplifier positive input; for high-side applications connect to the bus-voltage side of the sense resistor, and for low-side applications connect to the load side of the sense resistor, with a common-mode range of -5 V to 110 V. |
