**Texas Instruments** · Current Sense Amplifiers · SC-70-6

INA199C1QDCKRQ1 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 voltage input for zero-current output level adjustment, accepts 0V to V+ |
| 2 | GND | power_in | Analog ground, provides reference ground for the device |
| 3 | V+ | power_in | Power supply voltage input, rated 2.7V to 26V |
| 4 | IN+ | input | Positive differential input connected to power side of shunt resistor with common-mode range -0.1V to 26V |
| 5 | IN- | input | Negative differential input connected to load side of shunt resistor with common-mode range -0.1V to 26V |
| 6 | OUT | output | Analog voltage output with 50V/V gain for INA199C1-Q1 variant, amplified sensed voltage from shunt resistor |
