14-Bit 40/65 MSPS IF Sampling Analog-To-Digital Converter
The AD9244 is a monolithic, single 5 V supply, 14-bit, 65 MSPS analog-to-digital converter with an on-chip, high performance, sample and hold amplifier and voltage reference. The AD9244 uses a multi-stage differential pipelined architecture with output error correction logic to provide 14-bit accuracy at 65 MSPS data rates and guarantees no missing codes over the full operating temperature range.
The AD9244 has an on-board, programmable voltage reference. An external reference can also be chosen to suit the DC accuracy and temperature drift requirements of the application.
A differential clock input is used to control all internal conversion cycles. The digital output data can be presented in straight binary or in twos complement format. 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 AD9244 is available in a 48 pin surface mount plastic package (48-LQFP) and is specified for operation over the industrial temperature range of (-40°C to +85°C).
