AD7769JP

ADCs/DACs - Special Purpose Overview

The AD7769JP is a high-performance, low-power, 16-bit analog-to-digital converter (ADC) from Analog Devices. It utilizes a sigma-delta architecture with an integrated digital filter for precision conversion of AC and DC signals. The device features a single-channel input and supports multiple power modes to optimize the trade-off between noise performance and power consumption. Key electrical specifications include a dynamic range of up to 108.5 dB with the FIR filter at 256 kSPS and an input bandwidth of 110.8 kHz. It offers configurable data rates and flexible filtering options, including sinc filters for wider bandwidth applications.

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type and temperature grade when ordering. The 'JP' suffix typically denotes a plastic DIP package with specific commercial or industrial temperature ranges. Confirm pin compatibility and voltage supply requirements against the official datasheet before integration. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7769JP when a single-channel, high-resolution ADC is required with flexible filtering capabilities. Choose this component over multi-channel variants if only one measurement path is needed. Evaluate the required output data rate versus power dissipation constraints to select the appropriate power mode. Consider the FIR filter for narrowband, high-dynamic-range applications or sinc filters for broader bandwidth needs.

ADCs/DACs - Special Purpose Part Context

The AD7769JP belongs to the AD776x family of sigma-delta ADCs, which are designed for high-precision data acquisition. This family includes multi-channel versions like the AD7768 and other resolutions. The AD7769 specifically targets applications demanding high linearity and low noise in a single-channel configuration, serving as a versatile platform for both isolated and non-isolated measurement modules.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include the AD7769ARZ for surface mount applications. For multi-channel requirements, the AD7768 series may be considered if pinouts allow adaptation. Verify that any substitute maintains the same 16-bit resolution and compatible supply voltage levels.
