Texas Instruments ADC3908Dx/ADC3908Sx 8-Bit High-Speed ADCs
Texas Instruments ADC3908Dx/ADC3908Sx 8-Bit High-Speed Analog-to-Digital Converters (ADCs) are a family of ultra-low-power 8-bit 125MSPS high-speed dual and single-channel ADCs. High-speed control loops benefit from the short latency of only one clock cycle. The ADC consumes only 90mW at 125MSPS, and its power consumption scales have lower sampling rates.
The Texas Instruments ADC3908Dx/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. The device is a pin-to-pin compatible family of ADCs with 8-bit 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.
