DESCRIPTION

The ADS7804 is a complete 12-bit sampling analog-to-digital

(A/D) converter using state-of-the-art CMOS structures. It

contains a complete 12-bit, capacitor-based, SAR A/D converter

with S/H, reference, clock, interface for microprocessor

use, and three-state output drivers.

The ADS7804 is specified at a 100kHz sampling rate, and

guaranteed over the full temperature range. Laser-trimmed

scaling resistors provide an industrystandard

±10V input range, while the innovative design

allows operation from a single +5V supply, with power

dissipation under 100mW.

The 28-pin ADS7804 is available in plastic 0.3 DIP and SO

packages, both fully specified for operation over the industrial

–40°C to +85°C range.
