ADMOD79JQ

ADCs/DACs - Special Purpose Overview

The ADMOD79JQ is a dual-channel, fully differential Sigma-Delta modulator manufactured by Analog Devices Inc. It integrates two fifth-order one-bit noise shaping modulators designed for high-resolution signal processing applications. The device operates with an on-chip voltage reference and supports simultaneous sampling across both channels. Key electrical specifications include a maximum sampling rate of 3.57 million samples per second (MSPS) and an operating temperature range from -40°C to +85°C. The component utilizes a surface-mount package suitable for automated assembly.

• Medical diagnostic equipment utilizing differential sensor interfaces
• Audio analysis systems requiring low-noise modulation stages

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix and package variant against the official Analog Devices datasheet to ensure compatibility with your design requirements. Confirm that the sourcing channel provides genuine components with traceable manufacturing history. Check for any regional distribution restrictions or supply limitations before finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a fully differential, dual-channel modulator is required rather than a standard ADC. Ensure the system design accommodates the 3.57 MSPS data rate and the specific power supply requirements associated with the integrated reference. Evaluate thermal management needs given the operating temperature range and power dissipation characteristics.

ADCs/DACs - Special Purpose Part Context

This part belongs to the ADMOD series of Sigma-Delta modulators from Analog Devices. It serves as a specialized front-end component for converting analog signals into digital bitstreams. Unlike complete ADCs, it focuses on modulation performance, often interfacing directly with downstream DSP cores or decimation filters in complex mixed-signal designs.
