●Product Details
●The AD9280 is a monolithic, single supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9280 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 AD9280 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 amplifier (SHA) 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 AD9280 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 which can be used with the most significant bit to determine low or high overflow.
●The AD9280 can operate with a supply range from +2.7 V to +5.5 V, ideally suiting it for low power operation in high speed applications.
●The AD9280 is specified over the industrial (-40°C to +85°C) temperature range.
