The SQ52133E is a 200V/V fixed Gain, low-power, highprecision, 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 microampere 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.
