Texas Instruments · Current Sense Amplifiers · SC-70-6
INA190A1QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 | input | Reference input that enables bidirectional current sensing with an externally applied voltage, and its voltage must stay within GND to VS. |
| 2 | GND | power_in | Analog ground. |
| 3 | VS | power_in | Analog power supply, 1.7 V to 5.5 V. |
| 4 | 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, with the common-mode range of -0.2 V to 40 V. |
| 5 | 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, with the common-mode range of -0.2 V to 40 V. |
| 6 | OUT | output | Analog voltage output equal to the gained-up voltage difference from IN+ to IN-, offset by the voltage applied to the REF pin. |
