The AD7899AR-3 is a high performance, low cost and low power CMOS analog-to-digital converter. It is the ideal choice for precision data acquisition applications, such as instrumentation and measurement systems. The AD7899AR-3 has been designed to provide low power dissipation and wide bandwidth, as well as a wide input range of ±10V. It provides a single-ended, 24-bit resolution, 16-channel analog-to-digital converter with a fast A/D conversion rate of 4MHz, low noise at 6mA typical, and low power dissipation.

The converter is composed of several internal functional blocks that are interconnected to produce the desired result. The main components include the input switch, voltage reference, analog-to-digital converter (ADC), buffer and multiplexer. The input switch allows access to multiple input channels while the voltage reference provides a stable and accurate voltage value to the ADC, which then converts the analog voltage into a digital form. A buffer is used to isolate the analog input channel from the digital output so that the applied signal is not distorted. Finally, the multiplexer controls the switching sequence between analog inputs and digital outputs.

The A/D conversion process begins with the selection of a specific input source. The switch allows the selection of one of the 16 analog input channels. The amplifier connected to the reference voltage supplies a voltage corresponding to the magnitude of the input from the selected channel. The output of the amplifier is sent to the ADC, which converts the analog signal into digital form as required by the system. The converted digital signals are stored in one of the four internal registers of the ADC, where they are output for further processing.

The AD7899AR-3 provides a high level of accuracy with a resolution of 18 bits and a maximum conversion error of less than 0.05%. It offers an operating temperature range from -40°C to +85°C, making it suitable for use in harsh industrial environments. It is also compatible with Fast Ethernet, CANbus, SPI and I2C buses. The AD7899AR-3 is available in 28-pin TSSOP and SSOP packages.

The AD7899AR-3 is a high-performance, cost-effective and low-power analog-to-digital converter. It is ideal for precision data acquisition applications and provides fast A/D conversion rates, wide input range and high accuracy. This makes it suitable for industrial applications including temperatures up to 85°C and is compatible with popular communication protocols. All this makes the AD7899AR-3 an ideal choice for a wide range of data acquisition applications.
