ADC0819 - 8-Bit Serial I/O A/D Converter

Description

The ADC0819 is an 8-Bit successive approximation A/D converter with simultaneous serial I/O.

The serial input controls an analog multiplexer which selects from 19 input channels or an internal half scale test voltage.

Features

  • Separate asynchronous converter clock and serial data I/ O clock.
  • 19-Channel multiplexer with 5-Bit serial address logic.
  • Built-in sample and hold function.
  • Ratiometric or absolute voltage referencing.
  • No zero or full-scale adjust required.
  • Internally addressable test voltage.
  • 0V to 5V input range with single 5V power supply.
  • TTL/MOS input/output compatible.
  • 28-pin molded chip carrier or 28-pin molded DIP Key Specifications.
  • Resolution: 8-Bits.

ADC0819 8-Bit Serial I/O A/D Converter with 19-Channel Multiplexer ADC0819 OBSOLETE September 26, 2009 8-Bit Serial I/O A/D Converter with 19-Channel Multiplexer General Description The ADC0819 is an 8-Bit successive approximation A/D converter with simultaneous serial I/O. The serial input controls an analog multiplexer which selects from 19 input channels or an internal half scale test voltage. An input sample-and-hold is implemented by a capacitive reference ladder and sampled data comparator. This allows the input signal to vary during the conversion cycle. Separate serial I/O and conversion clock inputs are provided to facilitate the interface to various microprocessors.
