ADS7808
DESCRIPTION
The ADS7808 is a complete 12-bit sampling analog-
to-digital using state-of-the-art CMOS structures. It
contains a 12-bit capacitor-based SAR A/D with S/H,
reference, clock, and a serial data interface. Data can
be output using the internal clock, or can be synchro-
nized to an external data clock. The ADS7808 also
provides an output synchronization pulse for ease of
use with standard DSP processors.
The ADS7808 is specified at a 100kHz sampling rate,
and guaranteed over the full temperature range. Laser-
trimmed scaling resistors provide various input ranges
including
±
10V and 0V to 5V, while an innovative
design operates from a single +5V supply, with power
dissipation under 100mW.
The 20-pin ADS7808 is available in a plastic 0.3" DIP
and in an SOIC, both fully specified for operation over
the industrial –40
°
C to +85
°
C range.
