3 Description

The ADC3910Dx and ADC3910Sx are a family ultralow

power 10-bit 125MSPS high-speed single and

dual channel analog-to-digital converters. High-speed

control loops benefit from the short latency of only

1 clock cycle. The ADC consumes only 92mW at

125Msps with a power consumption that scales with

lower sampling rates.

The device uses DDR, HDDR, SDR or serial CMOS

interface to output the data from +1.8V to +3.3V

to accommodate various receiver requirements. The

device implements analog monitoring function by

event triggered interrupts per channel using a

digital comparator with programmable high and low

thresholds, hysteresis, and event counter. The device

is a pin-to-pin compatible family of ADCs with 8

and 10-bit resolution and different speed grades. The

device is available in a 32-pin VQFN package, and

supports industrial temperature range from -40 to

+105°C.
