Product description
MAX4466 is a low-power amplifier optimized for use as a microphone preamplifier. It combines very low supply current with high gain bandwidth. With its Rail-to-Rail® output, high open-loop gain (AVOL), and excellent power-supply and common-mode rejection, it operates reliably even in noisy environments. The MAX4466 is decompensated for a minimum stable gain of +5 V/V and delivers a 600 kHz gain-bandwidth product.
Specifications:
- Supply voltage: 2.4 V – 5.5 V
- Low quiescent current: 24 µA (typ.)
- Excellent PSRR: 112 dB
- Excellent CMRR: 126 dB
- High open-loop gain: 125 dB (at RL = 100 kΩ)
- Rail-to-Rail® outputs
- Gain bandwidth: 600 kHz at AV ≥ 5
- Package: 5-pin SOT23-5
Typical applications:
- Microphone preamplifiers
- Hearing aids
- Mobile phones
- Voice recognition
- Digital dictation devices
- Headsets
- Portable computers
