GENERAL DESCRIPTION
The AD9203 is a monolithic low power, single supply, 10-bit,
40 MSPS analog-to-digital converter, with an on-chip voltage
reference. The AD9203 uses a multistage differential pipeline
architecture and guarantees no missing codes over the full
operating temperature range. Its input range may be adjusted
between 1 V and 2 V p-p.
The AD9203 has an onboard programmable reference. An
external reference can also be chosen to suit the dc accuracy
and temperature drift requirements of an application.
An external resistor can be used to reduce power consumption
when operating at lower sampling rates. This yields power
savings for users who do not require the maximum sample rate.
This feature is especially useful at sample rates far below 40
MSPS. Excellent performance is still achieved at reduced power.
For example, 9.7 ENOB performance may be realized with only
17 mW of power, using a 5 MHz clock.
A single clock input is used to control all internal conversion
cycles. The digital output data is presented in straight binary or
twos complementary output format by using the DFS pin.
