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 devel- opment 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 suc- cessive channels and sampling single-channel inputs at frequen- cies 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 over- flow 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. PRODUCT HIGHLIGHTS Low Power The AD9280 consumes 95 mW on a 3 V supply (excluding the reference power). In sleep mode, power is reduced to below 5 mW. Very Small Package The AD9280 is available in a 28-lead SSOP package. Pin Compatible with AD876-8 The AD9280 is pin compatible with the AD876-8, allowing older designs to migrate to lower supply voltages. 300 MHz Onboard Sample-and-Hold The versatile SHA input can be configured for either single- ended or differential inputs. Out-of-Range Indicator The OTR output bit indicates when the input signal is beyond the AD9280’s input range. Built-In Clamp Function Allows dc restoration of video signals. REV. E 2010 |
