 Description
The DIO221X series is a high-side current-sense
amplifier with voltage output and can sense drops
across shunts at common-mode voltage from -0.1 V
to 75 V. The choices of gain are 20 V/V, 50 V/V, and
100 V/V, with the according bandwidths of 440 kHz,
110 kHz, and 65 kHz.
The DIO221X series is integrated with an open-drain
comparator and internal reference at 0.6 V voltage.
By pulling or grounding the pin, the comparator can
be made transparent or latched as needed.
The DIO221X series operates from single 3 V to 40 V
supply under -40°C to 125°C, with a maximum supply
current of 620 μA.
