FDA901-VYT

Overview

The FDA901-VYT is a quad bridge Class-D digital input power amplifier from STMicroelectronics, designed for automotive applications. It integrates a high-performance D/A converter with powerful MOSFET outputs in a BCD technology. The device supports I2S and TDM digital inputs at sampling frequencies of 44.1 kHz, 48 kHz, 96 kHz, and 192 kHz. It delivers up to 50 W per channel into a 4 Ω load at 15.2 V. Key features include integrated low-pass filters within the feedback loop, I2C configurability, and real-time load current acquisition.

Feature Summary

Integrates a 110 dB dynamic range D/A converter with Class-D outputs for high efficiency
Supports I2S and TDM digital audio inputs with flexible sampling rates
Includes output low-pass filters within the feedback loop for superior linearity
Provides real-time load current monitoring via I2C and I2S data lines

Applications

Car radio and in-vehicle entertainment systems
Automotive audio amplification requiring low voltage operation
Applications needing sophisticated speaker monitoring and diagnostics

Procurement Notes

Verify the specific suffix 'VYT' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required digital input protocols (I2S/TDM) and I2C bus voltages (3.3 V/1.8 V). Confirm AEC-Q100 qualification status for your target automotive application tier.

Selection Notes

Select this component for designs requiring integrated digital-to-analog conversion alongside power amplification. It is suitable for systems prioritizing space savings and reduced external component count. Consider its low voltage operation capability if designing for start-stop vehicle architectures. Verify thermal management requirements for the intended output power levels.

Part Context

The FDA901 belongs to STMicroelectronics' portfolio of automotive power amplifiers utilizing BCD technology. This family targets the body and convenience segment, specifically in-vehicle entertainment. The device addresses the need for high efficiency and advanced diagnostic capabilities in modern car radios.
