AD9202

The AD9202 is a monolithic, single supply, 10-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9202 uses a multistage differential pipeline architecture at 32 MSPS data rates and guarantees no missing codes over the full operating temperature range.

The input of the AD9202 has been designed to ease the development of both imaging and communications systems. The user can select a variety of input ranges and offsets and can drive the input either single-ended or differentially.

The sample-and-hold (SHA) amplifier is equally suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and beyond the Nyquist rate. AC coupled input signals can be shifted to a predetermined level, with an onboard clamp circuit. The dynamic performance is excellent.

The AD9202 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application.

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

The AD9202 can operate with supply range from 2.7 V to 5.5 V, ideally suiting it for low power operation in high speed portable applications.

The AD9202 is specified over the commercial (0°C to +70°C) temperature range.
