ADS7809U

The ADS7809 is a complete 16-bit sampling Analog-toDigital (A/D) converter using state-of-the-art CMOS structures. It contains a 16-bit capacitor-based Successive Approximation Register (SAR) A/D converter with sample-andhold, reference, clock, and a serial data interface. Data can
be outputted using the internal clock, or can be synchronized
to an external data clock. The ADS7809 also provides an
output synchronization pulse for ease of use with standard
DSP processors.
The ADS7809 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 ADS7809 is available in a 0.3″ SO-20, and is fully
specified for operation over the industrial –40°C to +85°C
range.
