The SQ52133E is a 200V/V fixed Gain, low-power, high-precision, high-side or low-side current-sense amplifier with ultra-low input bias current, suitable for bidirectional or unidirectional current measurements. The common mode voltage range of the SQ52133E is from -0.2V to +70V, independent of the supply voltage.
The SQ52133E has an ultra-low input bias current (500pA typical). Compared with other current-sense amplifiers, this feature allows larger current-sense resistors to be used to enable current measurements in the micro-ampere range.
The supply voltage range of the SQ52133E is 1.8V to 5.5V and the device draws 62µA quiescent current. It is offered in a SOT363 package and is specified over the extended industrial temperature range of -40°C to 125°C.
