Data Acquisition applications encompass a wide range of analog and digital electronics. Analog to Digital Converters (ADCs) perform the critical task of converting electrical signals from analog to digital so that computers and other devices can interpret the data. The AD7705BRUZ-REEL7 is an Analog-to-Digital Converter (ADC) designed for a variety of data acquisition applications requiring an extremely low power, low noise and low cost solution. This device can convert small analog signals into a digital code with high accuracy and low noise.

The AD7705BRUZ-REEL7 operates with industry standard 3V and 5V supply voltages and is the core component of a multi-channel data acquisition system. The AD7705BRUZ-REEL7 features an onboard S/H (Sample and Hold) amplifier and 16 bits of resolution on the ADC. This device can page through six different input channels with software control. The AD7705BRUZ-REEL7 also offers a multiplexer for changing the input channel easily.

The wide-variety of applications for the AD7705BRUZ-REEL7 include digital thermometers and other environmental monitoring systems, automotive crash testing, industrial process control, medical monitoring, and instrumentation. The AD7705BRUZ-REEL7 has a low power consumption and low noise making it ideal for applications involving battery operated and portable equipment that require accurate data acquisition. This device is also suitable for Portable Medical Equipment where low power operation and excellent accuracy are required.

The working principle of the AD7705BRUZ-REEL7 is based on the use of the integrating track-and-hold circuit used to sample the analog input and the subsequent conversion of that sample into a digital code. The AD7705BRUZ-REEL7 uses a differential amplifier to accurately measure the input voltage over a wide range of input voltages. The data is then latched onto a succession of registers using a high speed serial interface.

The AD7705BRUZ-REEL7 consists of a sample/hold circuit, an integrating A/D converter, and a digital filter. The sample and hold circuit is used to store the input analog voltage and then releases it to the A/D converter. The A/D converter then converts the analog level into a digital code which is outputted by the digital filter in a serial format.

The digital filter is used to reduce time domain ripples, providing high accuracy and low noise. The digital filter provides a maximum conversion rate of 100 kHz and the device can be operated in either 16 bit mode or 14 bit mode. The AD7705BRUZ-REEL7 provides an improved signal-to-noise ratio and a low harmonic distortion.

The AD7705BRUZ-REEL7 is a cost-effective solution for data acquisition applications requiring a precision, low-power and low noise ADC. The device comes with a wide range of features and advantages, such as high resolution, a low power consumption, high accuracy, and a low noise floor. The integrative track-and-hold circuit and digital filter on board the device make it an ideal choice for precision data acquisition.
