DESCRIPTION

The ADS8515 is a complete 16-bit sampling

analog-to-digital (A/D) converter using state-of-the-art

CMOS structures. It contains a complete 16-bit,

capacitor-based, SAR A/D converter with sample and

hold (S/H), reference, clock, interface for

microprocessor use, and 3-state output drivers.

The ADS8515 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 ADS8515 is available in a 28-pin SSOP package

and is fully specified for operation over the industrial

–40°C to 85°C temperature range.
