Bidirectional, On-The-Fly Programmable Gain, Current-Sense Amplifier with Wide Measurement Range MAX49918 General Description The MAX49918 is a high-precision current-sense amplifier (CSA) with an I2C programmable gain option from 10V/V to 200V/V in 8 steps. The multiple programmable gain options offer maximum flexibility for the user to change gain on-the-fly. The IC operating input common-mode range from -5V to +70V, with protections that extend down to -6V and up to +80V, thus providing protection against reversebattery and high-voltage spikes. The low input offset of ±1μV (typ) and low gain error of ±0.01% (typ) make this device best-suited for highprecision current measurements.
