Description: The front end of the DAC is configured differentially using dual eight-input IC multiplexer 1H6216 and three LM156 operational amplifiers. Following the differential amplifier is the programmable gain stage, which includes a low-pass filter on the output that feeds into the IH5110 sample and hold amplifier. The output of the IH5110 is connected to the comparator input, specifically the negative input of the LM301, through the internal 10 kΩ feedback resistor of the AD7541 multiplying digital-to-analog converter. The AD7541, along with a ±10-V reference and successive approximation logic, constitutes the 2's complement analog-to-digital converter.
The described circuit features a differential front end that enhances signal integrity by minimizing common-mode noise. The dual eight-input multiplexer (1H6216) allows for the selection of multiple input signals, which are then processed by the operational amplifiers (LM156) configured in a differential arrangement. This configuration provides improved linearity and reduced distortion, essential for high-precision applications.
The programmable gain stage that follows the differential amplifier allows for dynamic adjustment of the signal amplitude, accommodating varying input levels and optimizing the performance of the subsequent stages. The low-pass filter serves to eliminate high-frequency noise, ensuring that only the desired signal components are passed to the sample and hold amplifier (IH5110). This amplifier captures the analog signal at a specific moment, maintaining its value for further processing.
The output of the IH5110 is directed to the comparator input of the LM301, which is configured as a part of the feedback loop. The internal 10 kΩ feedback resistor of the AD7541 is crucial for maintaining stability and linearity in the conversion process. The AD7541 operates as a multiplying digital-to-analog converter, enabling precise control over the output voltage level based on the digital input provided.
In conjunction with a ±10-V reference and successive approximation logic, the AD7541 facilitates the operation of a 2's complement analog-to-digital converter. This configuration is ideal for applications requiring accurate digital representation of analog signals, making it suitable for various electronic systems where high fidelity and precision are paramount.The front end of the DAC is configured differentially using dual eight-input IC multiplexer 1H6216 and three LM156 op amps.
