2.2W, Low-EMI, Stereo, Class D Power Amplifiers

with DirectDrive Headphone Amplifiers

General Description

Features

The MAX9752/MAX9753/MAX9754 combine a high-effi-

ciency, filterless, stereo Class D audio power amplifier

with a DirectDrive™ headphone amplifier in a single

device. The Class D amplifier operates from a single

4.5V to 5.5V supply and provides 2.2W per channel into

a 4Ω load. The headphone amplifier operates from a

single 3V to 5.5V supply, and uses Maxim’s DirectDrive

architecture to produce a ground-referenced output

from a single supply.

♦ PC2001 Compliant

♦ 2.2W Class D Stereo Speaker Amplifier

♦ Pin-for-Pin Compatible with Class AB

MAX9750/MAX9751/MAX9755

♦ 85% Efficiency (R = 8Ω, P

= 1W)

OUT

♦ 62mW DirectDrive Headphone Amplifier

♦ High PSRR (70dB at 1kHz)

The MAX9754 features a Class D stereo speaker ampli-

fier and headphone driver. The MAX9752 adds an ana-

log volume control and a BEEP input. The MAX9753

adds a stereo 2:1 input multiplexer. All devices feature

logic-selectable gain, and a headphone sense input

that detects the presence of a headphone.

♦ Analog Volume Control (MAX9752)

♦ Beep Input with Glitch Filter (MAX9752)

♦ 2:1 Stereo Input MUX (MAX9753)

♦

8kV ESD-Protected Headphone Outputs

The MAX9752/MAX9753/MAX9754 come in 28-pin thin

QFN (5mm x 5mm x 0.8mm) packages, and are speci-

fied over the extended -40°C to +85°C temperature

range. For a pin-for-pin-compatible Class AB version of

these devices, refer to the MAX9750/MAX9751/

MAX9755 data sheet.

♦ No Output DC-Blocking Capacitors

♦ Industry-Leading Click-and-Pop Suppression
