Overview
The FAN7031MTFX is a stereo audio amplifier manufactured by Fairchild Semiconductor, now part of onsemi. It operates as a Class-AB power amplifier with a maximum output power of 2.45 W into a 4 Ohm load. The device supports a supply voltage range from 2.7 V to 5.5 V and features a total harmonic distortion plus noise (THD+N) of 0.2%. It includes two channels with a gain of 21.3 dB and accepts differential inputs. The component is housed in a TSSOP-EP-20 package and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Stereo Class-AB amplification architecture for dual-channel audio processing
- Differential input configuration to improve signal integrity
- Integrated thermal protection mechanisms for operational safety
Applications
- Portable multimedia devices requiring low-voltage stereo audio
- Consumer electronics utilizing single-supply operation
- Battery-powered audio systems needing high efficiency
Procurement Notes
Verify the manufacturer status carefully, as Fairchild Semiconductor operations have been integrated into onsemi. Confirm that the specific suffix 'MTFX' corresponds to the tape and reel packaging variant rather than the tube version. Ensure compatibility with current supply chain requirements given the corporate transition history.
Selection Notes
Select this component when a stereo solution is required with a single power supply rail between 2.7 V and 5.5 V. The differential input capability makes it suitable for noisy environments. Consider the TSSOP-EP-20 package for its thermal dissipation properties compared to standard packages without exposed pads.
Part Context
This component belongs to the FAN7031 series of audio amplifiers. The 'FAN7031MTFX' designation specifically indicates the Fairchild Semiconductor origin and the tape-and-reel packaging format. It is functionally equivalent to the onsemi FAN7031MTF, differing primarily in packaging and branding due to the acquisition.
Replacement Considerations
The FAN7031MTF is the direct functional equivalent under the onsemi brand. Verify pinout compatibility and ensure the packaging difference (tube vs. tape and reel) does not impact assembly processes.
