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
