DESCRIPTION
The
ADS8509
analog-to-digital (A/D) converter using state-of-the-art
CMOS structures. It contains a complete 16-bit,
capacitor-based, successive approximation register
(SAR) A/D converter with sample-and-hold, refer-
ence, clock, and a serial data interface. Data can be
output
using
the
internal
synchronized to an external data clock. The ADS8509
also provides an output synchronization pulse for
ease of use with standard DSP processors.

The ADS8509 is specified at a 250-kHz sampling rate
over the full temperature range. Precision resistors
provide various input ranges including ±10 V and 0 V
to 5 V, while the innovative design allows operation
from a single +5-V supply with power dissipation
under 100 mW.
The ADS8509 is available in 20-pin SO and 28-pin
SSOP packages, both fully specified for operation
over the industrial -40°C to 85°C temperature range.
