概要
Description
MAX4466EXK+T is Maxim’s evaluation kit for the MAX4466 low-noise microphone preamplifier. It provides a ready-to-test board to evaluate the device in single-supply mic-pre applications. The kit includes the MAX4466 on a compact PCB with a mic-bias network, input/output coupling, gain-setting components, and connectors plus documentation. Key features: ultra-low input noise, single-supply operation (about 2.7–5.5 V), adjustable gain via the external feedback network, and rail-to-rail output suitable for direct ADC or line-coupled use. Typical applications: handheld recorders, headsets, speech interfaces, and portable audio devices. How to use: connect a microphone to the input, supply power, and route the output to an ADC or line-in; adjust gain by changing the external resistor values. Benefits: fast, repeatable evaluation of noise, gain, and headroom before integrating the MAX4466 into a design.
Features
Key features of the MAX4466EXK+T (microphone preamplifier):
- Ultra-low-noise mic preamp optimized for electret/microphone capsules
