Part details & applications

The AD9237 is a monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS Analog to Digital Converter with a high performance sample-and-hold amplifier and voltage reference. The AD9237 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 temperature range.

The wide bandwidth, truly differential SHA allows for a variety of user-selectable input ranges and offsets 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. With significant power savings over previously available analog to digital converters, the AD9237 is suitable for applications imaging and medical ultrasound.

A single-ended clock input is used to control all internal conversion cycles. The digital output data is presented in straight binary, twos complement, or gray code formats. An out-of-range (OTR) signal indicates an overflow condition, which can be used with the most significant bit to determine low or high overflow.

Fabricated on an advanced CMOS process, the AD9237 is available in a 32-pin chip scale package and is specified over the industrial temperature range (-40°C to +85°C).

PRODUCT HIGHLIGHTS

Operating at 65 MSPS, the AD9237 consumes a low 190 mW and only consumes 135 mW at 40 MSPS and 90 mW at 20 MSPS.
The AD9237 operates from a single 3V power supply, and features a separate digital output driver supply to accommodate 2.5V and 3.3V logic families.
The patented SHA input maintains excellent performance for input frequencies beyond Nyquist, and can be configured for single-ended or differential operation.
The AD9237 is pin compati
