DAC3154IRGCR

Digital To Analog Converters Overview

The DAC3154IRGCR is a dual-channel, 10-bit digital-to-analog converter (DAC) from Texas Instruments, operating at a maximum sample rate of 500 MSPS. It features 12-/10-bit wide LVDS inputs with an internal FIFO for chip-to-chip synchronization. The device provides current sourcing outputs with a compliance range of –0.5V to 1V and dissipates approximately 460mW. At 20 MHz IF, it achieves an SNR of 62 dBFS and SFDR of 76 dBc. It operates within an industrial temperature range of –40°C to +85°C and is housed in a 64-pin QFN (9x9mm) package.

Digital To Analog Converters Procurement Notes

Verify the full part number DAC3154IRGCR against official Texas Instruments documentation to confirm the IRGCR suffix denotes the specific reel packaging variant. Ensure compatibility with system requirements for LVDS signaling and current sink termination before procurement. Cross-reference the datasheet revision date to validate parameter accuracy.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel, high-speed DAC with 10-bit resolution is required for baseband or intermediate frequency generation. Compare spectral performance metrics such as SNR and SFDR against alternative devices if higher dynamic range is needed. Consider pin compatibility with the DAC3164 or DAC3174 if future scalability to 12-bit or 14-bit resolutions is anticipated within the same footprint.

Digital To Analog Converters Part Context

The DAC3154 belongs to a family of 500 MSPS digital-to-analog converters that includes the DAC3164 (12-bit), DAC3174 (14-bit), and single-channel variants DAC3151, DAC3161, and DAC3171. These devices share a common pinout and form factor, facilitating design flexibility across different resolution requirements while maintaining consistent board layout constraints for high-speed signal integrity.

Digital To Analog Converters Replacement Considerations

The DAC3164 serves as a direct pin-compatible upgrade offering 12-bit resolution. For 14-bit requirements, the DAC3174 is available within the same package. Single-channel alternatives include the DAC3151, DAC3161, and DAC3171.
