19-3509; Rev 2; 8/08 EVALUATION KIT AVAILABLE Stereo DirectDrive Headphone Amplifier with BassMax, Volume Control, and I2C MAX9723 General Description Features The MAX9723 stereo DirectDrive® headphone amplifier 62mW, DirectDrive Headphone Amplifier with BassMax and volume control is ideal for portable Eliminates Bulky DC-Blocking Capacitors audio applications where space is at a premium and per- 1.8V to 3.6V Single-Supply Operation formance is essential. The MAX9723 operates from a sin-gle 1.8V to 3.6V power supply and includes features that Integrated 32-Level Volume Control reduce external component count, system cost, board High 90dB PSRR at 1kHz space, and improves audio reproduction. Low 0.006% THD+N The headphone amplifier uses Maxim s patented Industry-Leading Click-and-Pop Suppression DirectDrive architecture that produces a ground-refer-enced output from a single supply, eliminating the need ±8kV HBM ESD-Protected Headphone Outputs for large DC-blocking capacitors. The headphone ampli- Short-Circuit and Thermal-Overload Protection fiers deliver 62mW into a 16 load, feature low 0.006%THD+N, and high 90dB PSRR. The MAX9723 features Low-Power Shutdown Mode (5µA) Maxim s industry-leading click-and-pop suppression. Software-Enabled Bass Boost (BassMax) The BassMax feature boosts the bass response of the I2C/SMBus-Compatible Interface amplifier, improving audio reproduction when using Available in Space-Saving, Thermally Efficient inexpensive headphones. The integrated volume con- Packages: trol features 32 discrete volume levels, eliminating the 16-Bump UCSP (2mm x 2mm x 0.62mm) need for an external potentiometer. BassMax and the 16-Pin Thin QFN (4mm x 4mm x 0.8mm) volume control are enabled through the I2C/SMBusTM-compatible interface. Shutdown is controlled through Ordering Information either the hardware or software interfaces. The MAX9723 consumes only 3.7mA of supply current PIN- PKG PART** TEMP RANGE at 1.8V, provides short-circuit and thermal-overload PACKAGE CODE protection, and is fully specified over the extended MAX9723_EBE-T* -40°C to +85°C 16 UCSP-16
