ZXCT199
26V, ZERO-DRIFT, BIDIRECTIONAL, HIGH-PRECISION CURRENT MONITOR
Description
The ZXCT199 series of current shunt monitors are designed to deal with very low sense voltages, enabling the use of very low value sense resistors to monitor large currents. The low offset voltage and zero-drift architecture enables current sensing with maximum drops across the shunt to as low as 10mV full-scale.
The ZXCT199 series has three fixed voltage gain options in 50V/V, 100V/V, and 200V/V. It can measure voltage across shunts at common-mode voltages from -0.1V to 26V, independent of supply voltage.
These parts operate from a 2.7V to 26V power supply with a maximum supply current of 100μA. All versions have a temperature range of -40°C to +125°C, and are offered in the SOT363 package.
