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,

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

● 3.2W Output Power into 4Ω at 5V

● 2.4mA Quiescent Current

● 92% Efficiency (R = 8Ω, P

= 1W)

12dB, and 15dB) in I S/left-justified mode set by a single

OUT

gain select input and a fixed 12dB gain in TDM mode.

● 25μV

Output Noise (A = 15dB)

RMS

The digital audio interface is highly flexible with the

MAX98357A supporting I S data and the MAX98357B

● Low 0.015% THD+N at 1kHz

● No MCLK Required

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

● Sample Rates of 8kHz to 96kHz

● Supports Left, Right, or (Left/2 + Right/2) Output

● Sophisticated Edge Rate Control Enables

Filterless Class D Outputs

● 77dB PSRR at 1kHz

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.
