Windows Vista-Compliant, Stereo Class AB Speaker  
Amplifiers and DirectDrive Headphone Amplifiers  
8/MAX790  
General Description  
Features  
The MAX9789/MAX9790 combine a stereo, 2W Class AB  
speaker power amplifier with a stereo 100mW  
DirectDrive® headphone amplifier in a single device. The  
MAX9789/MAX9790 are designed for use with the  
Microsoft Windows Vista® operating system and are fully  
compliant with Microsoft’s Windows Vista specifications.  
The headphone amplifier features Maxim’s DirectDrive  
architecture that produces a ground-referenced output  
from a single supply to eliminate the need for large DC-  
blocking capacitors, as well as save cost, board space,  
and component height. A high +90dB PSRR and low  
0.002% THD+N ensures clean, low-distortion amplifica-  
tion of the audio signal.  
Microsoft Windows Vista Compliant  
Class AB 2W Stereo BTL Speaker Amplifier  
100mW DirectDrive Headphone Amplifier  
Eliminates Costly, Bulky DC-Blocking Capacitors  
Excellent RF Immunity  
Integrated 120mA LDO (MAX9789)  
High +90dB PSRR, Low 0.002% THD+N  
Low-Power Shutdown Mode  
Click-and-Pop Suppression  
Short-Circuit and Thermal-Overload Protection  
Available in 32-Pin Thin QFN (5mm x 5mm x  
0.8mm) Package  
Separate speaker and headphone amplifier control  
inputs provide independent shutdown of the speaker  
and headphone amplifiers, allowing speaker and head-  
phone amplifiers to be active simultaneously, if  
required. The industry-leading click-and-pop suppres-  
sion circuitry reduces audible transients during startup  
and shutdown cycles.

The MAX9789 features an internal LDO that can be used  
as a clean power supply for a CODEC or other circuits.  
The LDO output voltage is set internally at 4.75V or can  
be adjusted between 1.21V and 4.75V using a simple  
resistive divider. The LDO is protected against thermal  
overloads and short circuits while providing 120mA of  
continuous output current and can be enabled indepen-  
dently of the audio amplifiers.  
No  
Note: All devices are specified over the -40°C to +85°C extended  
temperature range.  
+Denotes a lead-free/RoHS-compliant package.  
*EP = Exposed pad.  
**Future product—contact factory for availability.  
By disabling the speaker and headphone amplifiers, and  
the LDO (for MAX9789), the MAX9789/MAX9790 enter  
low-power shutdown mode and draw only 0.3µA.  
Simplified Block Diagrams  
The MAX9789/MAX9790 operate from a single 4.5V to  
5.5V supply and feature thermal-overload and output  
short-circuit protection. Devices are specified over the  
-40°C to +85°C extended temperature range.
