Texas Instruments INA199 | Demoboard TIDA-00753

Description

The TIDA-00753 reference design demonstrates high accuracy wide range AC current measurement for a three phase motor using the INA199 zero drift current shunt monitor. The design also has low power consumption of 25mW for Gain stage of 200 as compared to a discrete solution. The design footprint and BOM cost is much smaller than a discrete solution due to the integrated high precision resistors inside the INA199.

Features

REAMRK: BOM and Schematics are added with EVM board.

• Wide common-mode range: –0.3 V to 26 V
• Offset voltage: ±150 μV (maximum)(Enables shunt drops of 10-mV full-scale)
• Accuracy– ±1.5% gain error (maximum overtemperature)– 0.5-μV/°C offset drift (maximum)– 10-ppm/°C gain drift (maximum)
• Choice of Gains:– INA199x1: 50 V/V– INA199x2: 100 V/V– INA199x3: 200 V/V
• Quiescent current: 100 μA (maximum)
• Packages: 6-pin SC70, 10-pin UQFN

Typical applications

• ID and FD Fans, Screw Feeders, and Feed Pumps (Steam Boiler)
