Electret Condenser Microphone Cartridge  
Preamplifier  
General Description  
Features  
ꢀ Replaces FET in Electret Condenser Microphone  
ꢀ 2.3V to 5.5V Single-Supply Operation  
ꢀ Low-Impedance Output (<0.4Ω)  
The MAX9810 microphone preamplifier is intended for  
use inside electret condenser microphone (ECM) car-  
tridges. Current solutions use a FET as an impedance  
converter. FETs have limited gain, are susceptible to  
noise and require additional components external to the  
ECM cartridge for biasing and amplification. The  
MAX9810 replaces the FET with a high-gain, high-noise  
rejection, low-output-impedance amplifier. Designed to  
be integrated inside the ECM cartridge, the MAX9810  
offers a flat frequency response, tightly controlled gain,  
increased sensitivity, and high-noise rejection greatly  
simplifying system design. Target applications include  
ECM cartridges in cell phones, PDAs, notebooks, and  
other portable audio devices.  
ꢀ High PSRR: 82dB  
ꢀ Three High-Gain Options:  
MAX9810A: 24dB  
MAX9810B: 27dB  
MAX9810C: 30dB  
ꢀ Internal Bias Voltage  
ꢀ Low Supply Current (670µA)  
ꢀ Rail-to-Rail® Output  
The MAX9810 operates from a single 2.3V to 5.5V sup-  
ply and consumes only 670µA of quiescent current. The  
device features an internally generated 1.5V DC bias,  
and is available in three internally fixed gain options  
(24dB, 27dB, and 30dB). The MAX9810 is specified  
over the extended temperature range (-40°C to +85°C)  
and comes in a tiny 4-bump chip-scale package  
(UCSP™) that is designed tofit inside the ECM cartridge.  
ꢀ No Output Phase Reversal During Overload  
Conditions  
ꢀ Available in a Tiny 4-Bump UCSP
