The device sense drops across the shunt resistor over a wide common-mode voltage range of -4 V to 110 V independent of the operating supply. The device achieves ultra-high precision current measurement accuracy under the combination of features such as an ultra-low offset voltage, a small gain error, and a high DC CMRR. The enhanced PWM rejection function provides a high level of suppression of large common-mode transients (ΔV/Δt) in systems that use pulse width modulation (PWM) signals. With this feature, the DIO2240 minimizes output interference and ringing during common-mode conversion. The device operates from a single power supply from 2.7 V to 5.5 V and consumes a low supply current. Four fixed gains are available: 10 V/V, 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The DIO2240 is available in TSSOP-8, MSOP-8 and SOIC-8 packages. It is specified over ambient temperature range of -40°C to 125°C, which meets the requirements of industry applications.
