The ADC3908Dx and ADC3908Sx are a family of ultra-low power 8-bit 125MSPS high-speed dual and single channel analog-to-digital converters. High-speed control loops benefit from the short latency of only 1 clock cycle. The ADC consumes only 90mW at 125MSPS with a power consumption that scales with lower sampling rates.

The ADC3908Dx and ADC3908Sx uses parallel DDR or SDR CMOS interface to output the data, and can be driven at +1.8V or +3.3V to accommodate various receiver requirements. The analog input and output interface can be easily configured via pin control (Interface Configuration Table). 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.
