Overview
The MP7770GF-P is a Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 45 W per channel into a 4-ohm load in stereo configuration or 90 W in mono bridge-tied-load (BTL) mode. The device operates on a supply voltage ranging from 9.5 V to 36 V. Key electrical specifications include a total harmonic distortion plus noise of 0.05%, an output current capacity of 8.5 A, and a shutdown quiescent current of 120 uA. It features a 20 kHz bandwidth and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports stereo single-ended or mono bridge-tied-load configurations for flexible power delivery.
- Integrates high-efficiency Class-D amplification technology.
- Includes integrated shutdown functionality for power management.
Applications
- High-fidelity audio systems
- Home theater receivers
- Portable speaker units
Procurement Notes
Verify the specific suffix 'P' against official MPS documentation to confirm reel packaging requirements. Confirm thermal design adequacy for the TSSOP-EP-28 package given the high power dissipation at maximum output. Ensure input voltage stays within the 9.5 V to 36 V operational limits during procurement validation.
Selection Notes
Select this component when high output power is required in a compact form factor. The dual-channel capability allows for independent left and right audio processing. Consider the thermal performance of the exposed pad package for heat dissipation in enclosed enclosures compared to lower-power alternatives.
Part Context
This part belongs to the Monolithic Power Systems audio amplifier portfolio. It utilizes a TSSOP-EP-28 surface-mount package designed for efficient thermal transfer. The device is categorized under Class-D amplifiers, distinguishing it from linear or other switching topologies in the manufacturer's lineup.
Replacement Considerations
Consult official MPS substitution guides for verified equivalents. Generic cross-references may not match the specific pinout or thermal characteristics of the TSSOP-EP-28 package.
