The MAX98356 is a digital pulse-density modulated

(PDM) input Class D power amplifier that provides Class

AB audio performance with Class D efficiency. This IC

offers five selectable gain settings (3dB, 6dB, 9dB, 12dB,

and 15dB) set by a single gain-select input (GAIN).

The MAX98356 takes a stereo pulse density modulated

(SPDM) input signal directly into the DAC. Data on the

rising edge of PDM_CLK is considered left-channel data

while data on the falling PDM_CLK edge is right channel.

The IC can be configured to produce a left channel, right

channel, or (left + right)/2 output from the stereo input

data. The IC also features an extremely robust digital

audio interface with very high wideband jitter tolerance

(12ns typ) on PDM_CLK.

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.

The IC is available in a 9-pin WLP package (1.345mm x

1.435mm x 0.64mm) and is specified over the -40NC to

+85NC temperature range.
