INA170EA

Texas Instruments · Current Sense Amplifiers · VSSOP-8

INA170EA from Texas Instruments, in a VSSOP-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 VIN- power_in Inverting differential sense input; accurate measurement is specified up to a 0.5V differential input, and a more-negative voltage here reduces the output current toward zero.
2 VIN+ power_in Noninverting differential sense input, connected as close as possible to the shunt; common-mode range is +2.7V to +60V, and a differential input up to 2V will not cause damage.
3 VREF power_in Reference voltage input that, when a positive voltage is applied, drives current through ROS to offset the output current from zero (VOS = (RL/ROS) × VREF).
4 GND power_in Ground reference for the device and for the load resistor RL at pin 6.
5 ROS passive Offset programming resistor connection; programming current through ROS is specified from 0 to 1 mA.
6 OUT output Output current terminal converted to voltage by external load resistor RL; maximum output is limited to (V+) − 0.7V − (VIN+ − VIN−) or VIN− − 0.5V, whichever is lower.
7 NC unconnected No internal connection; leave unconnected.
8 V+ power_in Supply voltage pin with an operating range of +2.7V to +40V (absolute maximum 40V to GND).

CAD (KiCad official)

  • Symbol: INA170EA
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ina170ea-etched.step / ina170ea-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina170ea.step / ina170ea.glb are the bare package body.
