IF Under sampling to 135 MHz The 3PA9280 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 3PA9280 can operate with a supply ranging from +2.7 V to +5.5 V, ideally suiting it for low power operation in high speed applications. The 3PA9280 is specified over the industrial (–40°C to +85°C) temperature range. PRODUCT HIGHLIGHTS
Low Power: The 3PA9280 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 3PA9280 is available in a 28 lead SSOP package.
Pin Compatible with ad9280: The 3PA9280 is pin compatible with the ad9280, allowing older designs to migrate to lower supply voltages.
100 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 3PA9280’s input range.
BuiltIn Clamp Function: Allows dc restoration of video signals. PRODUCT DESCRIPTION The 3PA9280 is a monolithic, single supply, 8bit, 32 MSPS analog to digital converter with an on chip sample and hold amplifier and voltage reference. The 3PA9280 uses multi-stage differential pipeline architecture at 32 MSPS data rates and guarantees no missing codes over the full operating temperature range. The input of the 3PA9280 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.
