AD574ASE/883B is a high-performance analog-to-digital converter in the Data Acquisition - Analog to Digital Converters (ADC). It provides excellent performance, low power consumption and wide dynamic range. The AD574ASE/883B is a versatile, low-power A/D converter integrating the most popular analog-to-digital conversion techniques, yielding a resolution of up to 16 bits. It is suitable for instrumentation and control applications requiring low voltage, low duty cycle and high speed.

The AD574ASE/883B has an on-chip multiplexer to select from 8 single-ended analog inputs or 4 differential input pairs, with an input voltage range from -3.3V to +3.3V. This multiplexer allows for user programmable settings for low volta[ge applications. Through the use of a 0.25uS output latch, the AD574ASE/883B can capture data from multiple scan paths. The output latch allows for flexible configurations, thus enabling a variety of complex applications.

The AD574ASE/883B supports different output interfaces, such as PULSE, 3 wire, 2 wire & 4 wire bus operation. Its output impedance is adjustable within a range of 1-15 Ohms. And the throughput rate of this device can be set up to 50-kSPS. In addition, it has an internal or external reference voltage option, allowing for precise adjustment of the output voltage. Furthermore, the AD574ASE/883B also supports an optional on-board voltage reference, allowing for simple, low-noise operation.

The AD574ASE/883B device is ideal for a wide range of applications, such as data acquisition, radiation monitoring, digital signal processing and process control. The device is used for temperature measurement in the chemical, automotive, and medical industries, as well as for providing control signals for automated manufacturing and diagnostics. This device is extremely flexible and offers very high resolution performance and minimal noise.

The principle of operation of the AD574ASE/883B is based on a differential amplifier, which converts an analog input signal into digital codes, suitable for further process. It uses delta-sigma modulation to convert the analog input signal into the corresponding digital codes. The device then uses a low pass filter to filter unwanted noise and distortion, and a sample and hold circuit to hold the sampled input signal. This filtered signal is then digitized using an ADC (analog-to-digital converter). Finally, the converted, digitalized data are stored in the device’s memory register, as well as output as digital signals to external circuits.

In summary, the AD574ASE/883B is a versatile, low-power analog-to-digital converter with a wide range of application fields. It provides excellent performance, low power consumption and wide dynamic range which makes it ideal for applications that require precise, low noise measurements. Furthermore, thanks to its simple operating principle, the AD574ASE/883B can be easily integrated in a wide range of applications, such as data acquisition, radiation monitoring, digital signal processing and process control.
