Electret Condenser Microphone – Omnidirectional, -36dB
$1.00
This electret condenser microphone is designed for general analog audio capture, voice input, intercom devices, access control systems, and consumer electronics. It features omnidirectional pickup, -36dB typical sensitivity, 2.2kΩ impedance, and a wide 1.0V–10V operating voltage range. It can also be used with the CamThink NE Sensor Expansion Board for prototyping.
1. -36dB Typical Sensitivity
Provides stable audio output for voice capture and ambient sound sensing, with a sensitivity range of -39dB to -33dB at 1kHz / 1Pa.
2. Omnidirectional Pickup
Captures sound from all directions, making it suitable for non-directional voice input, compact devices, and flexible installation layouts.
3. 2.2kΩ Standard Impedance
Designed for common microphone bias circuits and analog audio front-end designs, with 2.2kΩ load resistance under standard test conditions.
4. Wide 1.0V–10V Supply Range
Supports a broad operating voltage range for different analog systems, with 2.0V used as the standard test voltage.
5. Low Current Consumption
Typical current consumption is 50µA, making it suitable for low-power audio capture applications and compact embedded devices.

Overview
The DGO6027DD(-L)CR is a standard electret condenser microphone for analog audio input and voice capture applications. It uses an omnidirectional pickup pattern and provides -36dB typical sensitivity, making it suitable for intercom systems, access control devices, small recording front ends, toys, and consumer electronics.
The microphone supports a 1.0V to 10V operating voltage range, 2.2kΩ impedance, and low typical current consumption of 50µA. It is suitable for conventional microphone bias circuits and analog front-end amplifier designs.
For evaluation and integration, the recommended test condition is VS=2.0V with RL=2.2kΩ. Proper ESD protection and controlled soldering conditions are recommended during assembly.
