CMOS or LVDS DDR digital outputs
Rev. 03 — 2 July 2012
Product data sheet
1. General description
The ADC1210S is a single-channel 12-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 ADC1210S 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 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 from
1 V to 2 V (peak-to-peak). With excellent dynamic performance from the baseband to
input frequencies of 170 MHz or more, the ADC1210S is ideal for use in communications,
imaging and medical applications.
