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 synchronized 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
specified 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 ADS7808 is available in a 0.3" SO-20, fully specified for
operation over the industrial –40
°
C to +85
°
C range.
