PRODUCTION DATA
The ADC3910Dx and ADC3910Sx are a family ultra-low 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.
