DAC1658D2G0NLGA8

Digital To Analog Converters Overview

The DAC1658D2G0NLGA8 is a dual-channel, 16-bit high-speed Digital-to-Analog Converter manufactured by Renesas Electronics Corporation. It supports maximum output update rates of 2.0 GSps and baseband input data rates up to 1.0 GSps via a JESD204B interface with four configurable lanes running at speeds up to 10 Gbps. The device features selectable x2, x4, and x8 interpolation filters, an embedded NCO for complex digital modulation, and Multiple Device Synchronization (MDS) compliant with JESD204B subclass I. It utilizes a VFQFP-N 56 package (8 mm x 8 mm) and operates within an industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'A8' indicates tape and reel packaging as specified in the manufacturer's documentation. Confirm that the component corresponds to the high common-mode output voltage variant designated by the 'DAC1658D' prefix. Ensure compatibility with the required 3.3 V analog supply specifications before procurement.

Digital To Analog Converters Selection Notes

Select this model when high common-mode output voltage is required compared to the low common-mode DAC1653D series. Verify that the system clocking architecture supports harmonic clocking if utilizing the internal dividers. Ensure the PCB layout accommodates the specific thermal requirements associated with the 56-pin VFQFP-N package.

Digital To Analog Converters Part Context

This component belongs to the DAC165xD family, which includes the DAC1653D and DAC1658D variants. The primary distinction lies in the analog output common-mode voltage levels, with the DAC1658D designed for higher common-mode applications. The family shares identical digital interfaces, interpolation architectures, and core performance metrics.

Digital To Analog Converters Replacement Considerations

The DAC1653D2G0NLGA8 serves as a functional substitute within the same package but provides low common-mode output voltage instead of high. Other DAC165xD variants share the same pinout and digital interface but differ in analog supply requirements and output characteristics.
