The ADC used in this interface module is a data acquisition component. It is a monolithic CMOS device with an 8-bit analog to digital converter with 8 channels multiplexer and microprocessor compatible control logic. The 8-bit A/D converter uses successive approximation as the conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation register. The 8 channels multiplexer can directly access any one of 8-single ended analog signals, and provides the logic for additional channel expansion. Signal conditioning of any analog input signal is eased by direct access to the multiplexer output, and to the input of 8-bit A/D converter. 8 channels multiplexer are built in this device, and they are Microprocessor compatible logic levels. This module needs external power supply, of +5V DC @ 300mA. Specifications: - 8 independent analog input channels.
- 0V to 5V analog input voltage range with single 5V supply.
- Easy to interface with all microprocessors.
- No zero adjust is required.
- Assembled in an elegant sloping cabinet.
Note: This experimental module can be interfaced to all Microprocessor trainers, Micro control trainers or IBM PC Add ? on card Model: IBL-IBR-1. |
