Overview
The ADC1015S is a single-channel 10-bit Analog-to-Digital Converter (ADC) designed for high dynamic performance and low power consumption. It operates at sample rates up to 125 Msps and features a pipelined architecture with output error correction, ensuring zero missing codes over the entire operating range. The ADC is supplied from a single 3 V source and supports output logic levels from 1.8 V to 3.3 V in CMOS mode, as well as Low Voltage Differential Signalling (LVDS) Double Data Rate (DDR) output standard. An integrated Serial Peripheral Interface (SPI) allows for easy configuration, and the device includes a SPI-programmable full-scale to adjust the input voltage range from 1 V to 2 V (peak-to-peak).
