Low-Power, Stereo Audio Codec

The MAX9867 is an ultra-low power stereo Audio CODEC designed for portable consumer devices such as mobile phones and portable gaming consoles. The device features stereo differential Microphone inputs that CAN be connected to either Analog or digital micro- phones. The single-ended line inputs, with configurable preamplifier, CAN be sent to the ADC for record or routed directly to the Headphone Amplifier for playback. An aux- iliary ADC path CAN be used to track any DC voltage. The stereo Headphone Amplifiers support differential, single-ended, and capacitorless output configurations. Using the capacitorless output configuration, the device CAN output 10mW into 32Ω Headphones Comprehensive click-and-pop circuitry suppresses audible clicks and pops during volume changes and startup or shutdown. Utilizing Maxim’s proprietary digital circuitry, the device CAN accept any available 10MHz to 60MHz system Clock This architecture eliminates the need for an external PLL and multiple crystal Oscillators The stereo ADC and DAC paths provide user-configurable voice- band or audioband digital Filters Voiceband Filters pro- vide extra attenuation at the GSM packet frequency and greater than 70dB stopband attenuation at fS/2. The MAX9867 operates from a single 1.8V supply, and supports a 1.65V to 3.6V Logic level. An I2C 2-wire seri- al Interface provides control for volume levels, signal mixing, and general operating modes. The MAX9867 is available in a tiny 2.2mm x 2.7mm, 0.4mm-ball-pitch, WLP package. A 32-pin 5mm x 5mm TQFN package is also available. By Maxim Integrated Products
