AD9236

Data Sheet 12-Bit, 80 MSPS, 3 V A/D Converter AD9236 FEATURES Single 3 V supply operation (2.7 V to 3.6 V) SNR = 70.4 dBc to Nyquist SFDR = 87.8 dBc to Nyquist Low power: 366 mW Differential input with 500 MHz bandwidth On-chip reference and sample-and-hold DNL = ±0.4 LSB Flexible analog input: 1 V p-p to 2 V p-p range Offset binary or twos complement data format Clock duty cycle stabilizer APPLICATIONS High end medical imaging equipment IF sampling in communications receivers WCDMA, CDMA-One, CDMA-2000 Battery-powered instruments Hand-held scopemeters Low cost digital oscilloscopes DTV subsystems GENERAL DESCRIPTION The AD9236 is a monolithic, single 3 V supply, 12-bit, 80 MSPS analog-to-digital converter featuring a high performance sampleand-hold amplifier (SHA) and voltage reference. The AD9236 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 80 MSPS and guarantee no missing codes over the full operating temperature range. The wide bandwidth, truly differential SHA allows a variety of user-selectable input ranges and common modes, including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available analog-to-digital converters, the AD9236 is suitable for applications in communications, imag...
