... BUILT-IN PRE-AMPLIFIER / ADC The LMV1024/LMV1026 are offered in a space saving small 6-bump micro SMD package in order to fit inside small ECM canisters. The LMV1024 or LMV1026 IC is placed on the PCB. This PCB forms the bottom of the microphone, which is placed in the cell phone. FIGURE 2. Built-in Pre-Amplifier / ADC Figure 3 depicts a cross section of a microphone with the IC inside the ECM canister ...

... Pa. A certain pressure on the electret of the microphone gives a certain voltage at the output of the microphone. Since the LMV1024 microphone has a digital output, the sensitivity will be stated in dB(Full Scale/Pascal) or dB(FS/Pa) as opposed www.national.com to conventional microphones. This section compares the var- ious microphone types and their sensitivity ...

... The output is expressed in dBFS and therefore the sensitivity is also stated in dB(FS/Pa) in- stead of dB(V/Pa). To calculate the digital output (Data) in dBFS the following equation can be written for the LMV1024/ LMV1026: Where, P ...

... REF ANALOG-TO-DIGITAL CONVERTER is REF The ADC used in the LMV1024/LMV1026 is an one bit sigma delta converter with a Pulse Density Modulated output signal (PDM). The output of this ADC can be either High (one) or Low (zero). Assume that the LMV1024/LMV1026 input is at the minimum level. In that case the DATA output will produce almost only “ ...
