INA199A1DCKR

INA199A1DCKR is the tape-and-reel SC70-6 ordering code for the Texas Instruments INA199 current-sense amplifier, listed by TI as ACTIVE. The A1 code is the 50 V/V gain variant, and every figure here is from the A1 column of the datasheet (SBOS469H): bandwidth of 80 kHz typical at that gain, gain error of ±0.03 % typical and ±1.5 % maximum over -40 °C to +125 °C, input offset of ±5 µV typical and ±150 µV maximum with drift of 0.1 µV/°C typical and 0.5 µV/°C maximum, common-mode rejection of 100 dB minimum and 120 dB typical, slew rate of 0.4 V/µs typical and quiescent current of 65 µA typical and 100 µA maximum, over a 2.7 V to 26 V supply and a -0.3 V to 26 V common-mode range. The selection point is shunt measurement in a 2 mm-class package: portable and space-constrained designs get a documented gain and offset budget in SC70-6 instead of a discrete difference-amplifier build. Selection advice: the higher-gain sibling codes share this pinout while their bandwidth falls (30 kHz and 14 kHz typical), so the A1 letter is the critical match point - a wrong-gain substitute returns a proportionally wrong current reading without any visible fault. Parameters verified against the TI INA199 datasheet SBOS469H (A1 electrical column and ordering information).
