BU9480F-E2

ADCs/DACs - Special Purpose Overview

The BU9480F-E2 is a 16-bit stereo digital-to-analog converter (DAC) designed for audio applications, manufactured by ROHM Semiconductor. It integrates an internal 2x oversampling interpolator to enhance signal fidelity. The device operates on a supply voltage ranging from 3.0V to 5.5V and utilizes a CMOS process for low current consumption. Key electrical characteristics include a typical full-scale output voltage of 2V peak-to-peak, a signal-to-noise ratio of 93dB, and total harmonic distortion of 0.05% at 1kHz. It supports serial data formats with a maximum clock frequency of 200kHz.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's official documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status distinct from the standard BU9480F. Ensure the source document explicitly defines this suffix before procurement planning.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring a low-pin-count stereo DAC solution. Verify that the system logic levels align with the specified input high/low voltage thresholds relative to VDD. Confirm that the required audio sample rate does not exceed the 200kHz BCLK limit defined in the absolute maximum ratings.

ADCs/DACs - Special Purpose Part Context

This part belongs to ROHM's multimedia IC portfolio, specifically targeting consumer electronics. The BU9480F series provides a cost-effective solution for basic audio playback functions where high channel count or complex filtering is not required.

ADCs/DACs - Special Purpose Replacement Considerations

The BD5209G-1 is listed as a similar level replacement in related ROHM documentation, though it is a voltage detector rather than a DAC. No direct pin-compatible DAC substitute is confirmed in the provided datasheet.
