The AD9238 is a dual, 3 V, 12-bit, 20/40/65 MSPS analog to digital converter. It features dual high performance sample-and-hold amplifiers and an integrated voltage reference. The AD9238 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy and guarantee no missing codes over the full operating temperature range at up to 65 MSPS data rates.
The wide bandwidth, differential SHA allows for a variety ofuser-selectable input ranges and offsets including single-endedapplications. It is suitable for various applications includingmultiplexed systems that switch full-scale voltage levels in successive channels and for sampling inputs at frequencies wellbeyond the Nyquist rate. The AD9238 is suitable for applicationsin communications, imaging and medical ultrasound.
Dual single-ended independent clock inputs are used to controlall internal conversion cycles. A Duty Cycle Stabilizer (DCS) is available on the AD9238-65 and can compensate for wide variationsin the clock duty cycle, allowing the converters to maintainexcellent performance. The digital output data is presented ineither straight binary or twos complement format. Out-of-rangesignals indicate an overflow condition, which can be used withthe most significant bit to determine low or high overflow.
Fabricated on an advanced CMOS process, the AD9238 is available in either a space saving 64-pin LQFP or 64-pin LF-CSP and is specified over the industrial temperature range (-40°C to +85°C).
