12-Bit, 80 MSPS, 3 V A/D Converter
The AD9236 is a monolithic, single 3V supply, 12-bit, 80 MSPS analog-to-digital converter with a high performance sample-and-hold (SHA) amplifier and voltage reference. The AD9236 uses a multi-stage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 80 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 power savings over previously available ADCs, the AD9236 is suitable for applications in communications, imaging, and medical ultrasound.
A single-ended clock input is used to control all internal conversion cycles. A duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent performance. The digital output data is presented in straight binary or twos complement 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 AD9236 is available in a 28-lead TSSOP and a 32-lead LFCSP and is specified over the industrial temperature range (-40°C to +85°C).
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs and DACs. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, frequency response plots, and more.
