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.
