Analog Devices Inc. AD9234BCPZRL7-500

Description
The AD9234 is a 12-bit, 1 GSPS/500 MSPS dual analog-to-digital converter (ADC) with 1.5 W per channel power consumption. It features a wide full power bandwidth of 2 GHz, buffered inputs with programmable input termination, and a flexible serial port interface (SPI) for controlling various product features and functions. The AD9234 also includes an internal ADC voltage reference, flexible termination impedance, optional decimate-by-2 DDC per channel, and small signal dither.
