Product details

The INA206AIDGST: RoHS3 compliant, which simplifies compliance declarations for assemblies shipped into regions with Restriction of Hazardous Substances directives.

High-side current sense with wide common-mode range

This is a high-side current monitor — it measures current by sensing the voltage drop across a shunt resistor placed between the power supply and the load, rather than on the ground return side. The input voltage range spans -16 V to 80 V, meaning it can monitor current on a 12 V automotive rail, a 24 V industrial bus, or a 48 V telecom supply, and it survives reverse-battery conditions down to -16 V without damage. Rated accuracy is ±3.5%, which sets the measurement uncertainty floor — for a 1 A full-scale shunt drop, the reported current could be off by up to 35 mA before any temperature or layout effects are added.

Temperature grade and package for board integration

Housed in a 10-VSSOP package (3.00 mm width MSOP footprint), the INA206AIDGST fits on compact mixed-signal boards where board area is tight; the 0.65 mm pin pitch is routable on a two-layer PCB with careful trace spacing. The 1 mA output current capability means the monitor can drive a downstream ADC input or a micro-controller analog pin directly, provided the input impedance of the load is high enough not to load the output.

Frequently asked questions

What is the INA206AIDGST accuracy and what does it mean for my measurement?

The INA206AIDGST has a ±3.5% accuracy specification. This means the output voltage representing the measured current can deviate from the true value by up to 3.5% of the reading, before any temperature drift or layout parasitics are factored in. For a 10 A full-scale measurement, the uncertainty is ±350 mA.

How does the INA206AIDGST compare to the INA234BIYBJR for a higher-accuracy design?

The INA234BIYBJR offers ±0.5% accuracy versus the INA206AIDGST's ±3.5%, making it the better choice when measurement precision is critical. However, the INA234BIYBJR operates from a 1.7 V supply and supports both high- and low-side sensing, while the INA206AIDGST handles a wide -16 V to 80 V input range on the high side. The packages differ — the INA206AIDGST is a 10-VSSOP, while the INA234BIYBJR comes in a smaller package. They are not pin-compatible, so a board layout change is required to swap between them.
