Texas Instruments ADC3910Dx 10-Bit 125MSPS ADCs

Texas Instruments ADC3910Dx 10-Bit 125MSPS Analog-to-Digital Converters (ADCs) are a family of 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 one clock cycle. The ADC consumes only 92mW at 125Msps with 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 an 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 eight and 10-bit resolution and different speed grades. The Texas Instruments ADC3910Dx is available in a 32-pin VQFN package and supports industrial temperature ranges from -40 to +105°C.
