MAX98356

PDM Input Class D Audio Power Amplifier

General Description

Features

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).

S Single-Supply Operation (2.5V to 5.5V)

S 3.2W Output Power into 4I at 5V

S 1.7mA Quiescent Current

S 92% Efficiency (R = 8I, P

= 900mW,

OUT

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.

V_DD= 3.7V)

S 29µV

Output Noise (A = 6dB)

RMS

S Low 0.013% THD+N at 1kHz

S Exceptionally High Jitter Tolerance

S Supported PDM�CLK Rates of 1.84MHz–4.32MHz

and 5.28MHz–8.64MHz

S Supports Left, Right, or (Left + Right)/2 Outputs

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.

S Sophisticated Edge Rate Control Enables

Filterless Class D Outputs

S 77dB PSRR at 217Hz

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.

S Low RF Susceptibility Rejects TDMA

Noise from GSM Radios

S Extensive Click-and-Pop Reduction Circuitry

S Robust Short-Circuit and Thermal Protection
