INA228AIDGSR

INA228AIDGSR is the complete order code for the Texas Instruments INA228 — an 85-V, 20-bit power, energy and charge monitor with I2C interface in VSSOP-10 (DGS), supplied on a 2,500-piece large tape and reel with part marking 228I — for 48-V telecom rails, industrial drives and battery systems up to 85 V common-mode. The datasheet (SLYS021, Rev. A) electrical table gives ±1 µV maximum shunt offset, 0.05% maximum gain error and 154 dB minimum CMRR across the -0.3 V to +85 V common-mode range — note the 85 figure is volts of common-mode range, not the CMRR. Selection advice: AIDGSR is the only reel code in TI's current package addendum; a 250-piece small-reel AIDGST appeared in older addenda but is not listed in the current one, so quote AIDGSR for production volumes. The INA228 series page on this site covers the family overview, and automotive builds use the separate INA228-Q1.
