PCM Input Class D Audio Power Amplifiers  
General Description  
Features  
The MAX98357A/MAX98357B are digital pulse-code mod-  
ulation (PCM) input Class D power amplifiers that provide  
Class AB audio performance with Class D efficiency. These  
ICs offer five selectable gain settings (3dB, 6dB, 9dB,

supporting left-justified data. Both ICs support 8 channel  
time division multiplexed (TDM) data. The digital audio  
interface accepts specified sample rates between 8kHz  
and 96kHz for all supported data formats. The ICs can  
be configured to produce a left channel, right channel, or  
(left/2 + right/2) output from the stereo input data. The ICs

operate using 16/24/32-bit data for I S and left-justified  
modes as well as 16-bit or 32-bit data using TDM mode.  
The ICs eliminate the need for the external MCLK signal  
that is typically used for PCM communication. This reduc-  
es EMI and possible board coupling issues in addition to  
reducing the size and pin count of the ICs.  
Low RF Susceptibility Rejects TDMA  
Noise from GSM Radios  
Extensive Click-and-Pop Reduction Circuitry  
Robust Short-Circuit and Thermal Protection  
Available in Space-Saving Packages:  
1.345mm x 1.435mm WLP (0.4mm Pitch)  
and 3mm x 3mm TQFN  
The ICs also feature a very high wideband jitter toler-  
ance (12ns typ) on BCLK and LRCLK to provide robust  
operation.  
Active emissions-limiting, edge-rate limiting, and over-  
shoot control circuitry greatly reduce EMI. A filterless  
spread-spectrum modulation scheme eliminates the need  
for output filtering found in traditional Class D devices and  
reduces the component count of the solution.  
Simplified Block Diagram  
The ICs are available in 9-pin WLP (1.345mm x 1.435mm  
x 0.64mm) and 16-pin TQFN (3mm x 3mm x 0.75mm)  
packages and are specified over the -40°C to +85°C tem-  
perature range.
