1 / 11 page 1 ® ADS7821 FEATURES q 100kHz min SAMPLING RATE q 0 to +5V INPUT RANGE q 86dB min SINAD WITH 20kHz INPUT q DNL: 16-bits “No Missing Codes” q SINGLE +5V SUPPLY OPERATION q PIN-COMPATIBLE WITH 12-BIT ADS7820 q USES INTERNAL OR EXTERNAL REFERENCE q FULL PARALLEL DATA OUTPUT q 100mW max POWER DISSIPATION q 28-PIN 0.3" PLASTIC DIP AND SOIC ADS7821 DESCRIPTION The ADS7821 is a complete 16-bit sampling A/D 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 three-state output drivers. The ADS7821 is specified at a 100kHz sampling rate, and guaranteed over the full temperature range. Laser- trimmed scaling resistors provide a 0 to +5V input range, with power dissipation under 100mW. The 28-pin ADS7821 is available in a plastic 0.3" DIP and in an SOIC, both fully specified for operation over the –25 °C to +85°C range. 16-Bit 10 µs Sampling CMOS ANALOG-to-DIGITAL CONVERTER ® Successive Approximation Register and Control Logic Clock Output Latches and Three State Drivers Three State Parallel Data Bus BUSY Comparator BYTE CS R/C CDAC Internal +2.5V Ref Buffer 4k Ω 0 to +5V Input REF CAP 5k Ω 20k Ω 6.66k Ω ©1996 Burr-Brown Corporation PDS-1323A Printed in U.S.A.
