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.
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.
