PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The UCD9090A has 11 monitor input pins (MONx) that are multiplexed into a 2.5V referenced 12-bit ADC. The monitor pins can be configured so that they can measure voltage signals to report voltage, current and temperature type measurements. A single rail can include all three measurement types, each monitored on separate MON pins. If a rail has both voltage and current assigned to it, then the user can calculate power for the rail. Digital filtering applied to each MON input depends on the type of signal. Voltage inputs have no filtering. Current and temperature inputs have a low-pass filter.
