Description: The ICL7135 typical application schematic diagram is illustrated in the following circuit. This Analog to Digital (A/D) converter incorporates all necessary active devices on a single CMOS integrated circuit, featuring multiplexed BCD output and digit drivers.
The ICL7135 is a highly integrated A/D converter designed for precision measurement applications. It converts analog signals into a digital representation, facilitating the processing and display of data in various electronic systems. The device operates on a single supply voltage, typically ranging from 5V to 15V, which simplifies power management in circuit designs.
The schematic typically includes the following key components:
1. **Input Signal Conditioning**: This section may consist of operational amplifiers configured as buffers or amplifiers to condition the analog input signal, ensuring it is within the acceptable range for the A/D conversion process.
2. **Reference Voltage Source**: A stable reference voltage is crucial for accurate A/D conversion. The ICL7135 can utilize an external reference voltage source or an internal reference, depending on the application requirements.
3. **Multiplexed BCD Output**: The ICL7135 features a Binary-Coded Decimal (BCD) output, which allows for easy interfacing with digital displays or further processing units. The multiplexing capability reduces the number of output lines needed, streamlining the design.
4. **Digit Drivers**: These components are essential for driving the display elements, such as seven-segment displays. The digit drivers control the on/off states of individual segments based on the BCD output from the A/D converter.
5. **Control Logic**: The control logic manages the operation of the A/D converter, including the timing of conversions and the selection of input channels if multiple inputs are present.
6. **Decoupling Capacitors**: These are placed close to the power supply pins of the ICL7135 to filter out noise and ensure stable operation.
The ICL7135 is suitable for applications in digital voltmeters, sensor interfaces, and other systems requiring precise analog-to-digital conversion. Its compact design and integration of essential components make it an efficient choice for engineers looking to implement A/D conversion in their electronic designs.ICL7135 Typical Application Schematic Diagram appears in the following circuit illustration.
