Description

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 ADS7812 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 > 10MW). 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 16-pin 0.3" plastic DIP or a 16-lead SOIC package.
