The AD9789BBCZRL is a high-performance, low power, monolithic, digital-to-analog converter (DAC) which belongs to the field of data acquisition. It can convert digital data into an analog signal in miniature packages and provide a wide range of applications, from video and telecommunications to medical imaging and sonar.

The AD9789BBCZRL offers an excellent dynamic performance, with an ENOB of 19-bits, thanks to its extremely low noise and low power consumption. It also provides a wide range of input range options, including DC and AC coupled, for greater flexibility. With its high precision sampling and advanced digital filter techniques, the AD9789BBCZRL provides superior audio performance in addition to its outstanding quality video performance.

The AD9789BBCZRL is available in two different packages. The LE1 has 8-pin PDIP and the LE2 provides 14-pin PDIP with an optional pin on the bottom right corner. The AD9789BBCZRL is also available with an on board voltage reference to simplify system design and reduce component cost.

The working principle behind the AD9789BBCZRL is that it utilizes the delta-sigma topology to convert the digital information into an analog signal. The digital data is first sampled and integrated by successive approximation registers which converts the data into a single bit stream. The conversion process is performed using a modulator which then converts the single bit stream into an analog signal using a DAC. The output values can be increased in steps of 1/2N, where N is the number of bits of resolution.

In order to convert the signals from one format to the other, the AD9789BBCZRL has a specialized circuitry to perform this conversion. A low pass filter is used to remove any unwanted noise from the signal before it is converted. The output of the filter is then fed into a synchronous sampler which can both sample the input signal and interpolate the output signal. This ensures that the output is of the same quality as the input.

The AD9789BBCZRL has an internal operating frequency range of up to 250 MHz and can operate at a temperature range of -40°C to 85°C. This high performance DAC is also power-optimized, consuming only 20 µA at full performance. The combination of its features makes the AD9789BBCZRL ideal for a variety of data acquisition applications.
