I C Programmable-Gain Amplifier  
for Audio Applications  
DS420  
General Description  
Features  
The DS4420 is a fully differential, programmable-gain  
amplifier for audio applications. It features a -35dB to  
Differential Inputs and Outputs  
-35dB to +25dB Adjustable Gain  
Low Output Noise  
2
+25dB gain range controlled by an I C interface and it  
is optimized to drive loads as low as 50Ω. The gain is  
adjustable in 3dB increments across the entire range.  
Low-Distortion Driving into a 50Ω Load  
2
Three address inputs, used to select the I C slave  
address, enable up to eight devices on a common bus.  
2
3dB Gain Steps Programmed through I C Interface  
5V Single Supply  
The product operates from a single 5V supply over a  
-20°C to +70°C temperature range. It is offered in a  
3mm x 3mm TDFN package.  
20kHz Bandwidth for All Gain Settings  
Small 3mm x 3mm x 0.8mm TDFN Package  
Up to Eight DS4420s can be Placed on the Same
