INA186A2IDDFT 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 | VS | power_in | Analog power supply voltage input; accepts 1.7 V to 5.5 V |
| 2 | ENABLE | input | Digital input enable pin; drive to VS to enable device and start current measurement, or drive to GND to disable and reduce quiescent current to 10nA; output enters high impedance state when disabled; must be externally driven or connected to VS if not used |
| 3 | REF | input | Analog reference input for bidirectional current sensing; externally applied voltage sets output offset for two-direction current measurement; connect to GND for unidirectional measurement or to VS/2 for bidirectional measurement |
| 4 | GND | power_in | Analog ground reference |
| 5 | OUT | output | Analog voltage output; provides amplified voltage difference from IN+ to IN- added to REF offset voltage; output swings from GND + 1mV to VS - 40mV |
| 6 | NC | unconnected | No internal connection; can be left floating, grounded, or connected to power supply |
| 7 | IN+ | input | Current sense amplifier positive input; for high-side applications connect to bus voltage side of sense resistor; for low-side applications connect to load side of sense resistor; accepts common-mode voltage from -0.2 V to +40 V |
| 8 | IN- | input | Current sense amplifier negative input; for high-side applications connect to load side of sense resistor; for low-side applications connect to ground side of sense resistor; accepts common-mode voltage from -0.2 V to +40 V |
