Description : 8-Bit, Microprocessor-Compatible, A/D Converters

The ADC080X family are CMOS 8-Bit, successive-approximation A/D Converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These Converters appear to the processor as memory locations or I/O ports, and hence no interfacing logic is required.

Advanced, 8-Bit Real-Time Control Microcomputers with A/D and D/A Converters

Description : 8-Bit µp-Compatible D/A converter

DESCRIPTION
The NE/SE5018/19 is a complete 8-Bit digital-to-analog converter subsystem on one monolithic chip. The data inputs have input latches which are controlled by a latch enable pin. The data and latch enable inputs are ultra-low loading for easy interfacing with all logic systems. The latches appear transparent when the LE input is in the low state. When LE goes high, the input data present at the moment of transition is latched and retained until LE again goes low. This feature allows easy compatibility with most microprocessors.

FEATURES
8-Bit resolution
• Input latches
• Low-loading data inputs
• On-chip voltage reference
• Output buffer amplifier
• Accurate to ± LSB (0.19%)
• Monotonic to 8 bits
• Amplifier and reference both short-circuit protected
Compatible with 8085, 6800 and many other µPs

APPLICATIONS
• Precision 8-Bit D/A Converters
A/D Converters
• Programmable power supplies
• Test equipment
• Measuring instruments
• Analog-digital multiplication

Description : 80C51 8-Bit microcontroller family 4K/128 OTP/ROM/ROMless, 8 channel 8 bit A/D, watchdog timer

DESCRIPTION
The Philips 8XC550 is a high-performance microcontroller fabricated with Philips high-density CMOS technology.
