MAX49918IATB+T规格书详情
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 reverse-battery 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 high-precision current measurements.
The IC operates from a supply voltage of +2.7V to +5.5V with a typical quiescent supply at 0.7mA. The device operates over the full -40°C to +125°C temperature range.
The IC features bidirectional current sensing and is offered in a 3mm x 3mm, 10-pin TDFN ackage.
