DESCRIPTION

The ADS8504 is a complete 12-bit sampling A/D

converter using state-of-the-art CMOS structures. It

contains a complete 12-bit, capacitor-based, SAR

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

microprocessor use, and 3-state output drivers.

The ADS8504 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 ADS8504 is available in a 28-pin SOIC package

and is fully specified for operation over the industrial

-40°C to 85°C temperature range.
