ASD0610
 Multi-Mode Quad Ultra Low Power 14-bit Analog-to-Digital Converter
Description

ASD0610 is a versatile high performance low power 14-bit quad analog-to-digital converter (ADC) with optional power saving modes. The different Reduced Power Dissipation Modes can be selected during operation to trade off power dissipation and accuracy. Low switching times between the Modes enables the system to continuously keep power dissipation and performance at the optimum level.

ASD0610 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and serial LVDS output data. Data and frame synchronization output clocks are supplied for data capture at the receiver. In 8-bit LVDS mode, each ADC is connected to two LVDS pairs, one for the 8 MSBs and one pair for the LSBs. Various modes and configuration settings can be applied to the ADC through the serial control interface (SPI). Each channel can be powered down independently and data format can be selected through this interface. A full chip idle mode can be set by a single external pin. Register settings determine the exact function of this pin.

ASD0610 is designed to easily interface with Field Programmable Gate Arrays (FPGAs) from several vendors.
