Product Overview
The INA216 is a Texas Instruments current shunt monitor in the Signal_Chain category. It is designed around a +1.8 V to +5.5 V operating common-mode input range and uses a single supply powered from the IN+ pin, also specified from +1.8 V to +5.5 V.
Four fixed-gain variants are covered: INA216A1 at 25 V/V, INA216A2 at 50 V/V, INA216A3 at 100 V/V, and INA216A4 at 200 V/V. Electrical specifications include 90 dB minimum and 108 dB typical common-mode rejection ratio, matching power-supply rejection ratio values, ±0.01% typical nonlinearity error, and 60 nV/√Hz typical input-referred voltage noise density.
Package options include WCSP-4 YFF and ThinQFN-10 RSW. Thermal resistance junction-to-ambient is specified as 160°C/W for YFF and 114.9°C/W for RSW. The specified operating temperature range is -40°C to +125°C, with absolute maximum operating temperature ratings extending from -55°C to +150°C.

Procurement Notes
When requesting a quote for INA216, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
