Part Details:

19-4130; Rev 0; 5/08 Low RF Susceptibility DirectDrive Stereo Head- phone Amplifier with 1.8V Compatible Shutdown MAX9724C/MAX9724D General Description Features The MAX9724C/MAX9724D 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 DirectDrive® architecture to produce a Low-Power Shutdown Mode, < 0.1µA ground-referenced output from a single supply, elimi- Adjustable Gain (MAX9724C) or Fixed -1.5V/V nating the need for large DC-blocking capacitors, sav- Gain (MAX9724D) ing cost, board space, and component height. The Low 0.02% THD+N MAX9724 suppresses RF radiation received by inputand 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 MAX9724C offers an externally adjustable gain while 2.5V to 5.5V Single-Supply Operation the MAX9724D has an internally preset gain of -1.5V/V. Low Quiescent Current (3.5mA) The MAX9724C/MAX9724D deliver up to 60mW per Available in Space-Saving Packages channel into a 32 load and have low 0.02% THD+N. 12-Bump UCSP (1.5mm x 2mm) An 80dB at 1kHz power-supply rejection ratio (PSRR) 12-Pin Thin QFN (3mm x 3mm x 0.8mm) allows these devices to operate from noisy digital sup-plies without an additional linear regulator. Ordering Information Comprehensive click-and-pop circuitry suppresses TOP audible clicks and pops on startup and shutdown. PART GAIN (V/V) PIN-PACKAGE MARK The MAX9724C/MAX9724D operate from a single 2.5V MAX9724CEBC+T Adj. 12 UCSP +AGE to 5.5V supply, consume only 3.5mA of supply current,feature short-circuit and thermal-overload protection, MAX9724CETC+ Adj. 12 TQFN-EP* +ABJ and are specified over the extended -40°C to +85°C MAX9724DEBC+T
