General Description

The ADC0808, ADC0809 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic.

The 8-bit A/D converter uses successive approximation as the conversion technique.

The converter

Overview

ADC0808/ADC0809 8-Bit μP Compatible A/D Converters with 8-Channel Multiplexer ADC0808/ADC0809 July 8, 2009 8-Bit μP Compatible A/D Converters with 8-Channel Multiplexer.

Key Features

  • a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation register. The 8-channel multiplexer can directly access any of 8-single-ended analog signals. The device eliminates the need for external zero and full-scale adjustments. Easy interfacing to microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI-STATE outputs. The design of the ADC0808, ADC0809 has been optimized by incorpora.
