Data Acquisition – Analog to Digital Converters (ADC) are analog to digital converters that are used to acquire digital data from an analog signal. One example of a popular ADC, which is often used in applications such as portable electronic devices, is the AD7894ARZ-2.

This ADC features a low power consumption of 1.6 mW, a fast settling time of 12 μs, a 16-bit resolution, a 25 kSPS sample rate, and a single 2.5 V reference voltage. It is made up of a differential amplifier, a sigma delta modulator, a low-pass filter, and an output buffer. The amplifier is responsible for amplify the incoming signal, and the sigma delta modulator is used to convert the amplified signal into a digital signal. The low-pass filter is then used to reduce noise, while the output buffer provides a clean digital output.

This ADC also features a single cycle conversion and woken latencies as low as 2.5 clock cycles. As for its special characteristics, the AD7894ARZ-2 offers adjustable settling time, rail-to-rail inputs, and long term stability. It operates from a single 2.5 V power supply and can be powered from either a 3V or 5V supply. It also contains a number of control pins, such as a Standby pin, a Ground Pin, and a Reset Pin.

The AD7894ARZ-2 has a number of applications, such as system monitoring and control (microcontrollers and DSP’s), digital audio and video, medical imaging and diagnostics, industrial automation, instrumentation and data acquisition, process control, and portable computing systems.

The AD7894ARZ-2 ADC is an ideal choice for those applications that require a fast and efficient Analog to Digital Converter and it is widely used in the industry. While it has a variety of features and applications, this ADC is most commonly used in portable electronic devices, such as smartphones and tablets, due to its low power consumption and fast settling time.
