AD9216

FEATURES Integrated dual 10-bit ADC Single 3 V supply operation SNR = 57.6 dBc (to Nyquist, AD9216-105) SFDR = 74 dBc (to Nyquist, AD9216-105) Low power: 150 mW/ch at 105 MSPS Differential input with 300 MHz 3 dB bandwidth Exceptional crosstalk immunity < -80 dB Offset binary or twos complement data format Clock duty cycle stabilizer APPLICATIONS Ultrasound equipment IF sampling in communications receivers 3G, radio point-to-point, LMDS, MMDS Battery-powered instruments Hand-held scopemeters Low cost digital oscilloscopes GENERAL DESCRIPTION The AD9216 is a dual, 3 V, 10-bit, 105 MSPS analog-to-digital converter (ADC). It features dual high performance sampleand-hold amplifiers (SHAs) and an integrated voltage reference. The AD9216 uses a multistage differential pipelined architecture with output error correction logic to provide 10-bit accuracy and guarantee no missing codes over the full operating temperature range at up to 105 MSPS data rates. The wide bandwidth, differential SHA allows for a variety of user selectable input ranges and offsets, including single-ended applications. The AD9216 is suitable for various applications, including multiplexed systems that switch full-scale voltage levels in successive channels and for sampling inputs at frequencies well beyond the Nyquist rate. Dual single-ended clock inputs are used to control all internal conversion cycles. A duty cycle stabilizer is available on the AD9216 and can compensate for wide variations in the clock duty...
