ADS7813
DESCRIPTION
The ADS7813 is a low-power, single +5V supply, 16-
bit sampling analog-to-digital converter. It contains a
complete 16-bit capacitor-based SAR A/D with a
sample/hold, clock, reference, and serial data inter-
face.
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 ADS7813 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.
