2 Functional Description
The MX884 converts a small voltage developed
across an external sense resistor (Rs) to a 10-bit
digital output. Pin IN connects to the 3V to 60V power
input. The external current sense resistor connects
between pins IN and LOAD. The nominal A/D range is
100 mV V(IN)-V(LOAD) across Rs. The A/D least
significant bit typically equals 0.1 mV across R

Inputs CS and SCK are TTL-level compatible, 5.5V
maximum input voltage. Inputs can be driven from
CMOS microcontrollers operating at supply voltages
of 2.4 to 5.5V. Serial data output pin SDO is configured
as open drain, maximum 5.5V external pull-up. SCK is
used internally to clock the successive approximation
register of the A/D.
