DESCRIPTION

The ADS7805 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, Successive

Approximation Register (SAR) A/D converter with

Sample-and-Hold (S/H), reference, clock, interface for microprocessor

use, and 3-state output drivers.

The ADS7805 is specified at a 100kHz sampling rate and

ensured over the full temperature range. Laser-trimmed

scaling resistors provide an industry-standard ±10V input

range while the innovative design allows operation from a

single +5V supply, with power dissipation under 100mW.

The ADS7805 is available in a 0.3 DIP-28 and an SO-28

package. Both are fully specified for operation over the

industrial –25°C to +85°C range; however, they will function

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