1. General description
The ADC1412D is a dual channel 14-bit Analog-to-Digital Converter (ADC) optimized for
high dynamic performance and low power consumption at sample rates up to 125 Msps.
Pipelined architecture and output error correction ensure the ADC1412D 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 an 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 ADC1412D is ideal for
use in communications, imaging and medical applications.
