Product details

What this current sense amplifier delivers

The Texas Instruments INA310A4IDGKR is a Zero-Drift current sense amplifier in an 8-VSSOP package, designed for single-supply operation from 2.7 V up to 20 V. It monitors current via a shunt resistor and outputs a single-ended voltage proportional to the sensed current. The Zero-Drift architecture holds input offset voltage to 5 µV, which means you get accurate low-side or high-side current measurement without trimming or calibration — critical for precision motor-phase monitoring, solenoid current regulation, or battery-charge tracking in industrial and automotive environments rated -40°C to 125°C.

Sourcing and lifecycle — active, no LTB risk

The INA310A4IDGKR carries an Active lifecycle status with ROHS3 compliance. No last-time-buy or end-of-life notices are on record. For volume BOM qualification, the part is sourced through independent distribution and quoted to order against an RFQ.

Frequently asked questions

Where can I buy INA310A4IDGKR?

This part is sourced through independent distribution channels and quoted to order against an RFQ. Contact us for current availability and pricing.

What is the bandwidth of INA310A4IDGKR?

The -3 dB bandwidth is 900 kHz, sufficient for fast current sensing in switching power converters and motor drives.

What are the alternatives to INA310A4IDGKR?

The INA254A1IPWAR is a pin-compatible Zero-Drift current sense amplifier with a 350 kHz bandwidth, suitable when lower bandwidth is acceptable. The INA4290A2IRGVR offers four channels in a single package but has a 1.1 MHz bandwidth and 2 V/µs slew rate.

What is the pinout of INA310A4IDGKR?

The part is in an 8-VSSOP package. The pinout follows the standard TI current sense amplifier layout; refer to the datasheet for the exact pin assignments.
