AD9689BBPZRL-2600 is a low-power, high-speed, 16-bit Sigma-Delta analog-to-digital converter (ADC) developed by Hittite Microwave Corporation. Its operating range extends from 3V to 5.5V and its primary feature is its low power consumption and high sampling rate of up to 50MS/s. In addition, it has a wide input dynamic range of up to ±5.5V and a high crosstalk immunity.

The AD9689BBPZRL-2600 provides a low noise, high-precision data acquisition system ideal for industrial and consumer applications such as precision measurement instruments and control systems. It offers a wide variety of features, including a programmable gain amplifier that allows users to adjust gain over a wide range, while maintaining excellent linearity and reducing distortion. It also has on-chip digital filtering functions, such as low-pass filters to reduce noise, and digital signal processing functions such as digital gain adjustment for improved quality.

The AD9689BBPZRL-2600 combines an Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) into one integrated device. It includes two half-bridge input channels for differential and single ended inputs, as well as two current monitor channels for use with transimpedance amplifiers. The ADC is a high-speed, low-power, 16-bit Sigma-Delta converter that features a high sample rate of 50MS/s. It also features an internal low-pass filter.

The ADC module of the AD9689BBPZRL-2600 is designed to be connected to an on-chip voltage reference, allowing users to precisely measure a range of analog signals. It has an integrated zero-cross detection block, enabling accurate extrapolation of signals with zero crossing by measuring the period of oscillations. Using a programmable gain amplifier, users can adjust the gain over a wide range without changing any external components.

The DAC module is a 12-bit digital-to-analog converter that provides a 1V to 4V output range and can work with up to 2kS/s. It can also be connected to an external reference to enjoy a wider input range of up to ±10V. It also includes a multiplexer that can be used to select one of four input signals and a low-power latch-up protection circuit for avoiding any malfunctions.

The working principle of the AD9689BBPZRL-2600 is based on its combination of a Sigma-Delta ADC and a Digital-to-Analog Converter (DAC). The ADC module is designed to receive analog signals, convert them into digital data, and store it in memory. The DAC takes the digital data and converts it back into an analog signal, allowing the user to process the signal as required.

In summary, the AD9689BBPZRL-2600 is a low-power, high-speed, 16-bit Sigma-Delta analog-to-digital converter (ADC) developed by Hittite Microwave Corporation. The low power consumption and high sampling rate of up to 50MS/s allows for efficient data acquisition in precision measurement instruments and control systems. Its combination of an ADC and DAC makes it suitable for a wide range of applications and its programmable gain amplifier and digital signal processing functions provide users with increased accuracy and reliability.
