AFE7070IRGZT

Digital To Analog Converters Overview

The AFE7070IRGZT is a dual-channel 14-bit digital-to-analog converter (DAC) operating at 65 MSPS, manufactured by Texas Instruments. It integrates a programmable fourth-order baseband filter and an analog quadrature modulator within a single package. The device features a direct digital synthesizer (DDS) combined with a 32-bit numerically controlled oscillator (NCO) and LVDS output buffers. It operates within a temperature range of -40°C to +85°C and utilizes a 48-VQFN (7x7 mm) surface-mount package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the component status as active or obsolete through official Texas Instruments channels prior to procurement. Ensure compatibility with the AFE7070EVM development kit for performance validation during the design-in phase.

Digital To Analog Converters Selection Notes

Select this component for applications requiring integrated baseband filtering and quadrature modulation in a compact form factor. Compare against the AFE7071 if additional digital signal processing features like LO and sideband suppression are required. Ensure the system supports the specified voltage domains and LVDS interface requirements.

Digital To Analog Converters Part Context

This part belongs to the AFE7070/AFE7071 family of high-performance analog front ends designed for wireless infrastructure. It serves as a specialized solution for converting digital baseband signals directly to RF frequencies, reducing the bill of materials by integrating multiple functions typically handled by discrete components.

Digital To Analog Converters Replacement Considerations

The AFE7071IRGZT is documented as a similar replacement option. Verify functional differences, specifically that the AFE7071 includes additional digital signal processing features not present in the AFE7070.
