LMV1024 / LMV1026
Analog to Digital Converter Amplifier for Electret
Microphones in micro SMD
General Description
The LMV1024/LMV1026 integrates a pre-amplifier and a
Sigma Delta modulator inside an Electret Condenser Micro-
phone (ECM). The output of the IC is a digital serial bit
stream, ideal for 4-wire Electret Condenser Microphones
(ECM).
This next generation digital ECM produces an over sampled
single bit stream to be connected directly to a DSP in a
digital audio system. The clock input of this IC is a user
adjustable clock frequency ranging between 1 and 3.25
MHz.
The LMV1024/LMV1026 enables a very robust output of an
ECM by eliminating the sensitive, low-level analog signal
forming the output of a conventional JFET ECM. The RF
immunity is greatly improved. This eases system design and
reduces external components. Furthermore this different
system partitioning of the Analog-to-Digital conversion en-
ables an all-digital baseband processor in mobile communi-
cation systems.
The LMV1024/LMV1026 is offered in a 6-bump microSMD
package, suitable for the smallest ECM canisters.
