General description

The ADC1212D is a dual channel 12-bit Analog-to-Digital Converter (ADC) optimized for

high dynamic performances and low power consumption at sample rates up to 125 Msps.

Pipelined architecture and output error correction ensure the ADC1212D 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 ADC1212D

is ideal for use in communications, imaging and medical applications.
