ICL7109
Description
The ICL7109 is a high performance, CMOS, low power integrating A/D converter designed to easily interface with microprocessors. The output data (12 bits, polarity and over-range) may be directly accessed under control of two byte enable inputs and a chip select input for a single parallel bus interface.
Key Features
- 12-Bit Binary (Plus Polarity and Over-Range) Dual Slope Integrating Analog-to-Digital Converter
- Byte-Organized, TTL Compatible Three-State Outputs and UART Handshake Mode for Simple Parallel or Serial Interfacing to Microprocessor Systems
- RUN/HOLD Input and STATUS Output Can Be Used to Monitor and Control Conversion Timing
- True Differential Input and Differential Reference
- Operates At Up to 30 Conversions/s
- On-Chip Oscillator Operates with Inexpensive 3.58MHz TV Crystal Giving 7.5 Conversions/s for 60Hz Rejection. May Also Be Used with An RC Network Oscillator for Other Clock Frequencies
