ADS7820

12-Bit 10µs Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

DESCRIPTION

FEATURES

The ADS7820 is a complete 12-bit sampling A/D

using state-of-the-art CMOS structures. It contains a

complete 12-bit, capacitor-based SAR A/D with S/H,

reference, clock, interface for microprocessor use, and

three-state output drivers.

● 100kHz min SAMPLING RATE

● 0 to +5V INPUT RANGE

● 72dB min SINAD WITH 45kHz INPUT

● ±1/2 LSB max INL AND DNL

● SINGLE +5V SUPPLY OPERATION

● PIN-COMPATIBLE WITH 16-BIT ADS7821

The ADS7820 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.

● USES INTERNAL OR EXTERNAL

REFERENCE

The 28-pin ADS7820 is available in a plastic 0.3" DIP

and in an SOIC, both fully specified for operation over

the industrial –40°C to +85°C range.

● COMPLETE WITH S/H, REF, CLOCK, ETC.

● FULL PARALLEL DATA OUTPUT

● 100mW max POWER DISSIPATION

● 28-PIN 0.3" PLASTIC DIP AND SOIC
