AD7674ACPZRL

Data acquisition is a process used to measure physical phenomena such as voltage, current, pressure, temperature, vibration and acceleration, and convert the measured values into digital counterpart for further processing. Analog to Digital Converters (ADC) are one of the tools used in the data acquisition process to convert physical signals into digital signals. AD7674ACPZRL is an advanced 12-bit, low-power analog-to-digital converter (ADC) featuring a wide input voltage range of ±10V and high accuracy with low distortion, making it an ideal choice for a variety of applications in data acquisition systems.

The AD7674ACPZRL features a low power consumption of 14mW, high speed of 100kSPS and a wide temperature range of -40 to +125°C. It is suitable for applications spanning industrial, process control, metrology, calibration, automotive and medical markets. The ADC comes with a ThermoElectric Calibration (TEC) system which allows for automated offset and full-scale corrections. The AD7674 is a multi-chip device which includes an integrated oscillator and voltage reference for maximum system flexibility and improved performance.

The working principle of the AD7674ACPZRL can be summarized as follows. The analog input signal is first converted from a voltage level to a current level using the on-chip programmable transconductor. The transconductor is then converted to a digital form by a Successive Approximation Register (SAR) ADC. The result is then sampled and held by the sampling switch, and then sent through the track/buffer and stored in a latch. After the latch is filled, the stored 12-bit digital output is sent to the output pins.

The features and advantages of the AD7674ACPZRL make it an ideal choice for a wide range of applications requiring fast and accurate data acquisition. Applications such as industrial and automotive control systems, process control, medical instrumentation, communication systems, data logging and high-speed analog-to-digital converters are to list a few. It is also suitable for high-precision, low-power applications in noisy environments.

The AD7674ACPZRL has shown to be an efficient and reliable ADC for data acquisition applications. It can deliver excellent performance with high speed, accuracy and low power consumption. The TEC calibration system ensures accurate and stable measurements with low distortion. This makes the AD7674ACPZRL an ideal choice for applications requiring high accuracy, low distortion and low power consumption.
