Data Acquisition - Analog to Digital Converters (ADC): AD7738BRU

The AD7738BRU is a low-noise, low-power, highly accurate 24-bit sigma-delta Analog to Digital Converter (ADC) with integral temperature sensor and 10-bit Digital to Analog Converter (DAC). It was developed by Analog Devices, Inc. to offer the best performance and versatile signal conditioning and data acquisition in a range of applications.

Many of these applications include industrial, medical, automotive and consumer signal processing. The ADC part is ideal for use in applications including weighing and balance scales, audio signal sampling from sensors, analog-to-digital signal conversion, signal monitoring and conditioning, and data acquisition. The high-resolution DAC provides flexibility and improved signal conditioning in consumer applications such as temperature control and automotive motor control.

AD7738BRU offers a significant advantage over its contemporaries in the form of an integrated Temperature Sensor. This temperature sensor feature gives the AD7738BRU an edge in temperature management enabling improved accuracy and stability of sensor-acquired analog signals. The integrated temperature sensor also enhances the efficiency of the ADC since it eliminates the need for an external temperature sensor.

The AD7738BRU features a versatile signal conditioning interface which allows the user to control either single-ended or differential inputs, selectable gain and offset scaling, and zero-scale error adjustment for ultra-low noise operation. It also features programmable data rate and power modes for battery-powered and other power-sensitive applications. The combination of power consumption and performance make the AD7738BRU uniquely suited for high-sensitivity, battery-powered applications with strict power budget requirements.

The ADC features a 24-bit sigma delta architecture with built-in overdrive and dynamic hysteresis which allows the ADC to acquire and convert signals with a wide dynamic range. The high resolution and low-noise nature of the ADC enables it to accurately detect signals with very small amplitudes and high-frequency components. In addition, the ADC also features a serial interface and programmable, temperature compensation modes which increase its accuracy and allow easy integration into data acquisition systems.

The AD7738BRU is an excellent choice for applications requiring high performance and data accuracy. Its high-resolution ADC and DAC, integrated temperature sensor, low-power operation, and versatile signal conditioning and data acquisition features make it an ideal fit for a wide range of applications.
