General description

The ADC1112D125 is a dual channel 11-bit Analog-to-Digital Converter (ADC) optimized

for high dynamic performance and low power consumption. Pipelined architecture and

output error correction ensure the ADC1112D125 is accurate enough to guarantee zero

missing codes over the entire operating range. Supplied from a single 3 V source, it can

handle output logic levels from 1.8 V to 3.3 V in Complementary Metal Oxide

Semiconductor (CMOS) mode, because of a separate digital output supply. It supports the

Low Voltage Differential Signalling (LVDS) Double Data Rate (DDR) output standard. An

integrated Serial Peripheral Interface (SPI) allows the user to easily configure the ADC.

The device also includes a programmable full-scale SPI to allow a flexible input voltage

range of 1 V (p-p) to 2 V (p-p). With excellent dynamic performance from the baseband to

input frequencies of 170 MHz or more, the ADC1112D125 is ideal for use in

communications, imaging and medical applications
