ADS7812 - Low-Power, Serial 12-Bit Sampling Analog-To-Digital Converter

The ADS7812 is a low-power, single +5V supply, 12-bit sampling analog-to-digital converter. It contains a complete 12-bit capacitor-based SAR A/D with a sample/hold, clock, reference, and serial data interface.

The converter can be configured for a variety of input ranges including ±10V, ±5V, 0V to 10V, and 0.5V to 4.5V. A high impedance 0.3V to 2.8V input range is also available (input impedance > 10M). For most input ranges, the input voltage can swing to +16.5V or –16.5V without damage to the converter.

A flexible SPI compatible serial interface allows data to be synchronized to an internal or external clock. The ADS7812 is specified at a 40kHz sampling rate over the –40°C to +85°C temperature range. It is available in a 0.3" DIP-16 or an SO-16 package.
