The AD7703AR is an integrated circuit (IC) component developed by Analog Devices. This 16-bit Sigma-Delta ADC (Analog-to-Digital Converter) is designed for precision measurements and data acquisition systems. It offers several key features that make it suitable for various applications.
One of the main features of the AD7703AR is its high-resolution ADC, which provides a 16-bit output for precise measurement of analog signals. With such high resolution, it enables accurate conversion of analog waveforms into digital data.
The IC also incorporates a Sigma-Delta modulator, which is responsible for oversampling the analog input signal and converting it into a single-bit stream. This technique reduces the impact of noise and improves the overall signal-to-noise ratio (SNR).
The AD7703AR operates from a single power supply ranging from 2.7V to 5.25V, allowing it to be easily integrated into a wide range of systems with different power requirements.
Another notable feature is its multiplexed analog input channels. The IC can handle two differential analog inputs or four single-ended inputs, providing flexibility for various sensor interface configurations.
Furthermore, the AD7703AR offers programmable gain options, allowing the user to select the appropriate gain level to suit the application's input signal range. This feature enhances the versatility of the IC in handling different types of signals.
The IC also includes an on-chip reference voltage generator, eliminating the need for external precision references
