MAX9707 - 3-Channel 2.3W Filterless Class D Amplifiers

Download the MAX9707 datasheet PDF. This datasheet also covers the MAX9706 variant, as both devices belong to the same 3-channel 2.3w filterless class d amplifiers family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX9706/MAX9707 combine three high-efficiency Class D amplifiers with an active crossover to provide stereo highpass outputs, and a mono lowpass output.

All three channels deliver up to 2.3W at 1% THD+N per channel into 4Ω when operating from a 5V supply.

Features

  • Maxim’s patented DirectDrive™ headphone amplifier, providing ground-referenced headphone outputs without the need for bulky DC-coupling capacitors. The headphone outputs are capable of delivering 95mW per channel into 16Ω from a 3.3V supply, and are protected against ESD up to ±8kV. The MAX9706/MAX9707 feature pin-programmable gain, synchronization inputs and outputs, and a shutdown mode that reduces supply current to less than 1µA. All amplifiers feature click-and-pop suppression circuitry. Bot.

19-3681; Rev 0; 12/05 KIT ATION EVALU E L B AVAILA www.DataSheet4U.com 3-Channel, 2.3W, Filterless Class D Amplifiers with Active Crossover General Description The MAX9706/MAX9707 combine three high-efficiency Class D amplifiers with an active crossover to provide stereo highpass outputs, and a mono lowpass output. All three channels deliver up to 2.3W at 1% THD+N per channel into 4Ω when operating from a 5V supply. An internal active filter processes the stereo inputs (left and right) into stereo highpass and mono lowpass outputs. The crossover frequency is pin-selectable to four different frequencies to accommodate a variety of speaker configurations. The internal Class D amplifiers feature low-EMI, spread-spectrum outputs. No output filters are required.
