PRODUCT HIGHLIGHTS
The AD9241 offers a complete single-chip sampling 14-bit,
analog-to-digital conversion function in a 44-pin Metric Quad
Flatpack.
Low Power and Single Supply
The AD9241 consumes only 60 mW on a single +5 V power
supply.
Excellent DC Performance Over Temperature
The AD9241 provides no missing codes, and excellent tempera-
ture drift performance over the full operating temperature range.
Excellent AC Performance and Low Noise
The AD9241 provides nearly 13 ENOB performance and has an
input referred noise of 0.36 LSB rms.
Flexible Analog Input Range
The versatile onboard sample-and-hold (SHA) can be configured
for either single-ended or differential inputs of varying input spans.
Flexible Digital Outputs
The digital outputs can be configured to interface with +3 V and
+5 V CMOS logic families.
PRODUCT DESCRIPTION
The AD9241 is a 1.25 MSPS, single supply, 14-bit analog-to-
digital converter (ADC). It combines a low cost, high speed
CMOS process and a novel architecture to achieve the resolution
and speed of existing hybrid implementations at a fraction of the
power consumption and cost. It is a complete, monolithic ADC
with an on-chip, high performance, low noise sample-and-hold
amplifier and programmable voltage reference. An external refer-
ence can also be chosen to suit the dc accuracy and temperature
drift requirements of the application. The device uses a multistage
differential pipelined architecture with digital output error correc-
tion logic to guarantee no missing codes over the full operating
temperature range.
The input of the AD9241 is highly flexible, allowing for easy
interfacing to imaging, communications, medical, and data-
acquisition systems. A truly differential input structure allows
for both single-ended and differential input interfaces of varying
input spans. The sample-and-hold amplifier (SHA) is equally
suited for both multiplexed systems that switch full-scale voltage
levels in successive channels as well as sampling single-channel
inputs at frequencies up to and beyond the Nyquist rate. Also,
the AD9241 performs well in communication systems employ-
ing Direct-IF Down Conversion since the SHA in the differen-
tial input mode can achieve excellent dynamic performance well
beyond its specified Nyquist frequency of 0.625 MHz.
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 (OTR) signal indicates an over-
flow condition which can be used with the most significant bit
to determine low or high overflow.
