DESCRIPTION

The ADS8505 is a complete 16-bit sampling A/D

converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, SAR

A/D with S/H, reference, clock, interface for

microprocessor use, and 3-state output drivers.

The ADS8505 is specified at a 250-kHz sampling

rate over the full temperature range. Precision

resistors provide an industry standard ±10-V input

range, while the innovative design allows operation

from a single +5-V supply, with power dissipation

under 100 mW.

The ADS8505 is available in 28-pin SOIC and 28-pin

SSOP packages, both fully specified for operation

over the industrial –40°C to 85°C temperature range.
