INA199A3DCKR from Texas Instruments, in a SC-70-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | input | Reference voltage input, 0 V to V+. Sets the output voltage that corresponds to zero differential input (VSENSE = 0), enabling bidirectional current sensing when biased to VS/2. |
| 2 | GND | power_in | Analog ground return for the device. |
| 3 | V+ | power_in | Analog power supply, 2.7 V to 26 V. Quiescent current is 100 µA (max) and is independent of the sensed common-mode voltage. |
| 4 | IN+ | input | Non-inverting analog input; connect to the supply (bus) side of the external shunt resistor. Common-mode input range is -0.3 V to 26 V (INA199Ax) and is independent of V+. |
| 5 | IN- | input | Inverting analog input; connect to the load side of the external shunt resistor. VSENSE = (VIN+ - VIN-) is amplified by the fixed gain of 200 V/V (A3 gain option). |
| 6 | OUT | output | Analog voltage output. VOUT = VREF + (Gain x VSENSE), with Gain = 200 V/V for the A3 variant. Output swing is limited by the V+ rail and load current. |
