DESCRIPTION
The ADS7813 is a low-power, single +5V supply, 16-bit
sampling analog-to-digital (A/D) converter. It contains a
complete 16-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 > 10MΩ). 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 ADS7813
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.
