About Max9812:

• The MAX9812/MAX9813 are single/dual-input, 20dB fixed-gain microphone amplifiers.
• They offer tiny packaging and a low-noise, integrated microphone bias, making them ideal for portable audio applications such as notebook computers, cell phones, and PDAs.
• These amplifiers feature a 500kHz bandwidth, rail-to-rail outputs, an industry-leading 100dB power-supply rejection ratio, and a very low 0.015% THD+N.
• Power-saving features include very low 230µA supply current and a total shutdown mode that cuts the combined supply and BIAS currents to only 100nA.
• PC2001 Compliant
• 100dB at 217Hz Power-Supply Rejection Ratio
• Very Low 230µA Quiescent Current
• Low 0.015% THD+N
