DESCRIPTION

•

±0.1% FSR Max Full-Scale Error With ±2

PPM/°C Drift

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.

•

Single 5-V Supply Operation

Pin-Compatible With ADS7805 (Low Speed)

and 12-Bit ADS8504/7804

•

Uses Internal or External Reference

Full Parallel Data Output

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.

70-mW Typ Power Dissipation at 250 KSPS

28-Pin SSOP and SOIC Packages

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.
