ADC122S051 - 2 Channel- 500 kSPS 12-Bit A/D Converter

General Description

The ADC122S051 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface.

Unlike the conventional practice of specifying performance at a single sample rate only, the ADC122S051 is fully specified over a sample rate range of 200 kSPS to 500 kSPS.

April 2005 www.DataSheet4U.com ADC122S051 2 Channel, 500 kSPS 12-Bit A/D Converter ADC122S051 2 Channel, 500 kSPS 12-Bit A/D Converter General Description The ADC122S051 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC122S051 is fully specified over a sample rate range of 200 kSPS to 500 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals at inputs IN1 and IN2. The output serial data is straight binary, and is compatible with several standards, such as SPI™, QSPI™, MICROWIRE, and many common DSP serial interfaces.
