Check for Samples: ADC78H89 FEATURES DESCRIPTION The ADC78H89 is a low-power, seven-channel
CMOS 12-bit analog-to-digital converter with a
conversion throughput of 500 KSPS. The converter is
based on a successive-approximation register
architecture with an internal track-and-hold circuit. It
can be configured to accept up to seven input signals
on pins AIN1 through AIN7. 1 23 Seven Input Channels
