The AD1851RZ-J Device is a special purpose converter that’s most commonly used in data acquisition applications. It’s an inexpensive alternative to a standard DAC, and it provides a simple way to store and retrieve sampled analog waveforms. The device can also be used for various digital-to-analog conversion tasks, such as digital-to-audio conversion and PCM modulation, as well as for general waveform playback.

This device features a 20-bit dynamic range, with a maximum output voltage range of 20 Vp-p. It supports sampling rates of up to 20 kHz, and is also capable of up to 200 kHz sample rate accuracy when combined with an external clock. The device also features selectable output filtering, which helps reduce noise and distortion.

The AD1851RZ-J supports single-ended and differential input modes. The differential input mode allows the device to accept input signals of up to ±10 Vp-p. The device has an adjustable reference voltage, allowing the range of the input signal to be tailored to suit the application. In addition, the device can be configured for operation in linear or logarithmic (dB) modes.

One of the main advantages of this device is its low power consumption. It draws around 1.75 mA at 3.3 V, making it a good choice for portable and battery-powered applications. The device is also rugged and reliable, with low jitter and crosstalk on the output stage.

The AD1851RZ-J device features an advanced architecture, designed to maximize flexibility and performance. The device is fully programmable, allowing the user to configure it for a variety of tasks. The device also has a self-calibration feature that ensures that the output is always accurate, even in noisy environments.

The device uses a simple block-structured architecture, with one block dedicated to the input stage, another to the ADC, and a third to the DAC. The ADC and DAC blocks are further divided into sub-blocks, allowing the user to configure it to the application’s requirements.

The input stage of the device is designed to accept analog signals from a variety of sources, including electret microphones and piezoelectric transducers. The signals are then filtered and amplified, before being converted to digital values by the ADC.

The ADC is a multi-bit sigma-delta converter, which provides a high signal-to-noise ratio and low distortion. The ADC is also programmable, allowing the user to set the conversion rate and resolution to suit the application.

The DAC is a 12-bit, voltage-output device. It is capable of producing analogue outputs of up to 20 Vp-p. The DAC also features adjustable filtering and noise reduction, which helps to reduce noise and distortion on the output.

The AD1851RZ-J device is a versatile converter, designed to provide high performance and flexibility in a wide variety of data acquisition applications. Its low power consumption and programmability make it an ideal choice for portable and battery-powered applications, while its multi-bit architecture ensures that it can handle high sampling rates and dynamic ranges.
