DESCRIPTION
The ADS8507 is a complete low power, single 5-V
supply,
16-bit
sampling
converter.
It
contains
capacitor-based, successive approximation register
(SAR) A/D converter with sample and hold, clock,
reference, and data interface. The converter can be
configured for a variety of input ranges including ±10
V, 4 V, and 5 V. For most input ranges, the input
voltage can swing to 25 V or –25 V without damage
to the converter.

16-BIT 40-KSPS LOW POWER SAMPLING ANALOG-TO-DIGITAL CONVERTER WITH
INTERNAL REFERENCE AND PARALLEL/SERIAL INTERFACE
analog-to-digital
a
complete
(A/D)
16-bit
A SPI compatible serial interface allows data to be
synchronized to an internal or external clock. A full
parallel interface with BYTE select is also provided to
allow the maximum system design flexibility. The
ADS8507 is specified at 40 kHz sampling rate over
the industrial -40°C to 85°C temperature range.
