Part Details:

19-3050; Rev 5; 2/08 EVALUATION KIT AVAILABLE Low-Cost, Mono/Stereo, 1.4W Differential Audio Power Amplifiers MAX9718/MAX9719 General Description Features The MAX9718/MAX9719 differential input audio power 2.7V to 5.5V Single-Supply Operation amplifiers are ideal for portable audio devices with internal speakers. The differential input structure Very High -93dB PSRR at 217Hz improves noise rejection and provides common-mode 1.4W into 4 at 1% THD+N (per Channel) rejection. A bridge-tied load (BTL) architecture mini- Differential Input mizes external component count, while providing high-quality, power audio amplification. The MAX9718 is a Internal Fixed Gain to Reduce Component Count single-channel amplifier while the MAX9719 is a dual- Adjustable Gain Option (MAX9718A/H/MAX9719A) channel amplifier for stereo systems. Both devicesdeliver 1.4W continuous average power per channel to 100nA Low-Power Shutdown Mode a 4 load with less than 1% THD+N while operating No Audible Clicks or Pops at Power-Up/Down from a single +5V supply. The devices are available as Improved Performance Pin-Compatible Upgrade adjustable gain amplifiers or with internally fixed gainsof 0dB, 3dB, and 6dB to reduce component count. to LM4895 (MAX9718D/G) A shutdown input disables the bias generator and 1.8V Logic Compatible amplifiers and reduces quiescent current consumptionto less than 100nA. The MAX9718 shutdown input can Ordering Information be set as active high or active low. These devices fea-ture Maxim s comprehensive click-and-pop suppres- PIN- TOP PART TEMP RANGE sion circuitry that reduces audible clicks and pops PACKAGE MARK during startup and shutdown. MAX9718AEBL-T -40°C to +85°C 3 x 3 UCSP ADX The MAX9718 is pin compatible with the LM4895, MAX9718AEBL+T -40°C to +85°C 3 x 3 UCSP +ADX and is available in 9-bump UCSPTM, 10-pin TDFN, and MAX9718AETB-T -40°C to +85°C
