Overview

ADS7805 ADS7805 ADS7805 SBAS020D – JANUARY 1996 – REVISED OCTOBER 2006 16-Bit, 10µs Sampling, CMOS ANALOG-to-DIGITAL CONVERTER FEATURES q 100kHz min SAMPLING RATE q STANDARD ±10V INPUT RANGE q 86dB min SINAD WITH 20kHz INPUT q ±3.
0 LSB max INL q DNL: 16 Bits No Missing Codes q SINGLE +5V SUPPLY OPERATION q PIN-COMPATIBLE WITH 12-BIT ADS7804 q USES INTERNAL OR EXTERNAL REFERENCE q FULL PARALLEL DATA OUTPUT q 100mW max POWER DISSIPATION q 0.
3" DIP-28 AND SO-28 DESCRIPTION The ADS7805 is a complete 16-bit sampling, Analog-toDigital (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.
