AD9235

Data Sheet FEATURES Single 3 V supply operation (2.7 V to 3.6 V) SNR = 70 dBc to Nyquist at 65 MSPS SFDR = 85 dBc to Nyquist at 65 MSPS Low power: 300 mW at 65 MSPS Differential input with 500 MHz bandwidth On-chip reference and SHA 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 Ultrasound equipment IF sampling in communications receivers IS-95, CDMA-One, IMT-2000 Battery-powered instruments Hand-held scopemeters Low cost digital oscilloscopes GENERAL DESCRIPTION The AD9235 is a family of monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS analog-to-digital converters (ADCs). This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9235 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20/40/65 MSPS data rates and guarantee no missing codes over the full operating temperat...
