ADS7805

SBAS020D – JANUARY 1996 – REVISED OCTOBER 2006

16-Bit, 10µs Sampling, CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 100kHz min SAMPLING RATE

● STANDARD ±10V INPUT RANGE

● 86dB min SINAD WITH 20kHz INPUT

● ±3.0 LSB max INL

The ADS7805 is a complete 16-bit sampling, Analog-to-

Digital (A/D) converter using state-of-the-art CMOS struc-

tures. It contains a complete 16-bit, capacitor-based, Suc-

cessive Approximation Register (SAR) A/D converter with

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

processor use, and 3-state output drivers.

● DNL: 16 Bits No Missing Codes

● SINGLE +5V SUPPLY OPERATION

● PIN-COMPATIBLE WITH 12-BIT ADS7804

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.

● USES INTERNAL OR EXTERNAL

REFERENCE

● FULL PARALLEL DATA OUTPUT

● 100mW max POWER DISSIPATION

● 0.3" DIP-28 AND SO-28

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.
