Part Details:

19-3457; Rev 2; 2/07 1.3W, Filterless, Stereo Class D Audio Power Amplifier MAX9701 General Description Features The MAX9701 stereo Class D audio power amplifier pro- Patented Spread-Spectrum Modulation Lowers vides Class AB amplifier audio performance with the Radiated Emissions benefits of Class D efficiency, eliminating the need for aheatsink while extending battery life. The MAX9701 Single-Supply Operation (2.5V to 5.5V) delivers up to 1.3W per channel into an 8 load while 1.3W Stereo Output (8, VDD = 5V, THD+N = 1%) offering 87% efficiency. Maxim s next-generation, low-EMI modulation scheme allows the amplifier to operate No LC Output Filter Required without an external LC filter while still meeting FCC EMI 87% Efficiency (RL = 8, POUT = 1000mW) emission levels. Less Than 0.1% THD+N The MAX9701 offers two modulation schemes: a fixed-fre-quency (FFM) mode, and a spread-spectrum (SSM) High 80dB PSRR mode that reduces EMI-radiated emissions. The MAX9701 oscillator can be synchronized to an external Fully Differential Inputs clock through the SYNC input, allowing synchronization of Integrated Click-and-Pop Suppression multiple Maxim Class D amplifiers. The sync output(SYNC_OUT) can be used for a master-slave application Typical Low Quiescent Current (9mA) where more channels are required. The MAX9701 fea- Typical Low-Power Shutdown Mode (0.1µA) tures a fully differential architecture, a full bridge-tied load(BTL) output, and comprehensive click-and-pop suppres- Short-Circuit and Thermal-Overload Protection sion. The device features internally set gains of 0dB, 6dB, Available in Thermally Efficient, Space-Saving 12dB, and 18dB selected through two gain-select inputs, Packages further reducing external component count. 24-Pin Thin QFN-EP (4mm x 4mm x 0.8mm) The MAX9701 features high 80dB PSRR, less than 0.1% 20-Bump UCSP (2mm x 2.5mm x 0.6mm) THD+N, and SNR in excess of 88dB. Short-circuit andthermal-overload protection prevent the device from Ordering Information being damaged during a fault condition. The MAX9701 isavailable in 24-pin thin QFN-EP (4mm x 4mm x 0.8mm), PIN- PKG PART TEMP RANGE and 20-bump UCSPTM (2mm x 2.5mm x 0.6mm) pack- PACKAGE CODE ages. The MAX9701 is specified over the extended MAX9701EBP-T -40°C to +85°C
