Digital Audio Amplifier Power Stage
D2-24044
Features
The D2-24044 device is a high performance, integrated
Class-D amplifier power stage. The four power stage
outputs are configurable as four separate Half-Bridge
outputs, as two Full-Bridge outputs, or combinations of
Half-Bridge and Full-Bridge. Individual power stage
overload monitoring, on-chip temperature monitoring,
and common alert logic outputs provide protection to
integrate with the final system’s controller.
• All Digital Class-D Power Stage
• 4 Configurable Power Stage Outputs Supporting:
- 2 Channels, Bridged
- 4 Channels, Half-Bridge
- 2 Channels, Half-Bridge, plus 1 Channel Bridged
• Output Power (Bridged)
- 25W (8Ω, <1% THD)
- 30W (8Ω, <10% THD)
• Single HV Supply - Wide 9V-26V Range
- Gate Drive Supply Internally-Generated
• Individual Channel Protection Monitoring
• Temperature and Undervoltage Monitoring
• Efficient 38 Ld HTSSOP Package
