AD9244

14-Bit, 40 MSPS/65 MSPS A/D Converter AD9244 FEATURES 14-bit, 40 MSPS/65 MSPS ADC Low power 550 mW at 65 MSPS 300 mW at 40 MSPS On-chip reference and sample-and-hold 750 MHz analog input bandwidth SNR > 73 dBc to Nyquist @ 65 MSPS SFDR > 86 dBc to Nyquist @ 65 MSPS Differential nonlinearity error = ±0.7 LSB Guaranteed no missing codes over full temperature range 1 V to 2 V p-p differential full-scale analog input range Single 5 V analog supply, 3.3 V/5 V driver supply Out-of-range indicator Straight binary or twos complement output data Clock duty cycle stabilizer Output-enable function 48-lead LQFP package APPLICATIONS Communication subsystems (microcell, picocell) Medical and high-end imaging equipment Test and measurement equipment GENERAL DESCRIPTION The AD9244 is a monolithic, single 5 V supply, 14-bit, 40 MSPS/65 MSPS ADC with an on-chip, high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9244 uses a multistage differential pipelined architecture with output error correction logic to provide 14-bit accuracy at 40 MSPS/65 MSPS data rates, and guarantees no missing codes over the full operating temperature range. The AD9244 has an on-board, programmable voltage reference. An external reference can also be used to suit the dc accuracy and temperature drift requirements of the application. A differential or single-ended clock input controls all internal conversion cycles. The digital output data can be presented in straight binary or in twos comp...
