GENERAL DEscriptION

The SGM4822/SGM4825 (single-input) and SGM4823/SGM4826 (dual-input) are low noise, low power, rail-to-rail, fixed-gain microphone amplifiers with integrated bias. The SGM4822/SGM4823 support power supply voltage from 3.3V to 5.5V and the SGM4825/SGM4826 support wide power supply voltage from 2.7V to 5.5V. The devices are suitable for portable audio applications. They feature low THD+N = 0.009% in active mode, 2.6MHz bandwidth and forced shutdown mode.

The SGM4822/SGM4823 power-saving features include automatic switching between low power monitor mode and low noise active mode, and the devices also provide latched push-pull output to wake up external MCU in sleeping mode. Two inputs of the SGM4823/SGM4826 allow two microphones to be multiplexed into one output.

The devices operate over an ambient temperature range of -40 to +85.
