ADI AD9237BCPZ-40

The AD9237 is a family of monolithic, single 3V supply, 12-bit, 20 MSPS/40 MSPS/65 MSPS analog-to-digital converters (ADC). This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9237 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20 MSPS/ 40 MSPS/65 MSPS data rates and guarantees no missing codes over the full operating temperature range. With significant power savings over previously available ADCs, the AD9237 is suitable for applications in imaging and medical ultrasound. Fabricated on an advanced CMOS process, the AD9237 is available in a 32-lead LFCSP and is specified over the industrial temperature range -40°C to +85°C.
