Part Details:

19-3597; Rev 5; 3/08 EVALUATION KIT AVAILABLE 60mW, DirectDrive, Stereo Headphone Amplifier with Low RF Susceptibility and Shutdown MAX9724A/MAX9724B General Description Features The MAX9724A/MAX9724B stereo headphone ampli- Improved RF Noise Rejection (Up to 67dB Over fiers are designed for portable equipment where board Typical Amplifiers) space is at a premium. These devices use a unique, No Bulky DC-Blocking Capacitors Required patented DirectDriveTM architecture to produce a Low-Power Shutdown Mode, < 0.1µA ground-referenced output from a single supply, elimi-nating the need for large DC-blocking capacitors, sav- Adjustable Gain (MAX9724A) or Fixed -1.5V/V ing cost, board space, and component height. The Gain (MAX9724B) MAX9724 suppresses RF radiation received by input Low 0.02% THD+N and supply traces acting as antennas and prevents the High PSRR (80dB at 1kHz) Eliminates LDO amplifier from demodulating the coupled noise. The Integrated Click-and-Pop Suppression MAX9724A offers an externally adjustable gain while 2.7V to 5.5V Single-Supply Operation the MAX9724B has an internally preset gain of -1.5V/V.The MAX9724A/MAX9724B deliver up to 60mW per Low Quiescent Current (3.5mA) channel into a 32 load and have low 0.02% THD+N. Available in Space-Saving Packages: An 80dB at 1kHz power-supply rejection ratio (PSRR) 12-Bump UCSP (1.5mm x 2mm) allows these devices to operate from noisy digital sup- 12-Pin Thin QFN (3mm x 3mm x 0.8mm) plies without an additional linear regulator. Ordering Information Comprehensive click-and-pop circuitry suppressesaudible clicks and pops on startup and shutdown. GAIN PIN- PKG TOP PART The MAX9724A/MAX9724B operate from a single 2.7V (V/V) PACKAGE CODE MARK to 5.5V supply, consume only 3.5mA of supply current, MAX9724AEBC+T Adj. 12 UCSP-12 B12-1 +ADH feature short-circuit and thermal-overload protection,and are specified over the extended -40°C to +85°C MAX9724AETC+
