Analog-to-digital converters (ADC) are devices that convert analog signals into digital signals. The AD7708BRZ-REEL is an example of such device. It features a 2-channel, low-power, single-bit, low-power sigma-delta analog-to-digital converter (ADC) with a sample-and-hold amplifier (SHA) and a multibit analog-to-digital converter that can be used in battery-operated applications, such as portable and wireless systems.

The AD7708BRZ-REEL enables design of systems where multiple types of sensors and analog signals are used, such as temperature, pressure and light sensors. This versatile ADC can provide 12-bit, 14-bit or 16-bit resolution with dynamic range of up to 80dB. It also has wide input voltage range, up to ±10V. With the combination of SHA and multibit ADC architecture, the device provides low-power operation, and is suitable for applications that require high-fidelity data acquisition from low-frequency input signals.

The AD7708BRZ-REEL operates on a single 2.7V to 5.25V supply. It features digital filter, temperature and voltage compensation, digital calibration and digital offset correction. The device is available in a tiny 3mm x 3mm 16-pin wafer chip scale package (WCCSP) or a 3mm x 3mm 16-lead SOT-23 package (SOT23-3).

The AD7708BRZ-REEL works by converting the analog signals into digital signals. This is done by first performing continuous sampling of the input signal and then performing A/D conversion. The input signal is first amplified and sampled by the SHA, and then passed to the multibit ADC for conversion. The ADC receives the differential amplified signal and performs a successive approximation process. This involves comparing the input signal voltage to a known reference voltage and repeating this process until the result is close enough to the actual voltage. The output of the ADC is a bit-wise representation of the input signal.

The AD7708BRZ-REEL is suitable for use in data acquisition systems, instruments, and embedded systems that require low power and resolution. Applications include portable medical instruments, industrial process control, instrumentation, and environmental monitoring. This device is versatile enough to be used in a variety of applications, including battery-powered systems, digital thermometers, voltage meters, and test and measurement systems.
