1 / 72 page  w WM8952 Mono ADC with Microphone Pre-amplifier WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews Pre Production, Rev 3.1, June 2011 Copyright ©2011 Wolfson Microelectronics plc DESCRIPTION The WM8952 is a low power, high quality mono ADC designed for portable applications such as wireless microphones or headsets. The device integrates support for differential or single ended microphone connections. External component requirements are reduced as no separate microphone amplifier is required. An advanced Sigma Delta Converter design is used to give high quality audio at sample rates from 8 to 48ks/s. A selectable high pass filter and four fully-programmable notch filters are also available in the signal path. An advanced mixed signal ALC function with noise gate is provided, supporting readback of PGA gain during ALC operation. The digital audio interface supports A-law and μ-law companding. An on-chip PLL is provided to generate the required Master Clock from an external reference clock. The PLL clock can also be output if required elsewhere in the system. The WM8952 operates at supply voltages from 2.5 to 3.6V, although the digital supplies can operate at voltages down to 1.71V to save power. Different sections of the chip can also be powered down under software control using the selectable two or three wire control interface. The device is supplied in a very small W-CSP package, offering high levels of functionality in minimum board area, with high thermal performance.
