Features
- The MAX4465–MAX4469 are micropower op amps optimized for use as microphone preamplifiers. They provide the ideal combination of an optimized gain bandwidth product vs. supply current, and low voltage operation in ultra-small packages.
- The MAX4465/MAX4467/MAX4469 are unity-gain stable and deliver a 200kHz gain bandwidth from only 24μA of supply current.
- The MAX4466/MAX4468 are decompensated for a minimum stable gain of +5V/V and provide a 600kHz gain bandwidth product.
- These amplifiers feature Rail-to-Rail outputs, high AVOL, plus excellent power-supply rejection and common-mode rejection ratios for operation in noisy environments.
- The MAX4467/MAX4468 include a complete shutdown mode. In shutdown, the amplifiers’ supply current is reduced to 5nA and the bias current to the external microphone is cut off for ultimate power savings.
- +2.4V to +5.5V Supply Voltage Operation
- Versions with 5nA Complete Shutdown Available (MAX4467/MAX4468)
- Excellent Power-Supply Rejection Ratio: 112dB
- Excellent Common-Mode Rejection Ratio: 126dB
- High AVOL: 125dB (RL = 100kΩ)
- Rail-to-Rail Outputs
- Low 24μA Quiescent Supply Current
- Gain Bandwidth Product: 200kHz (MAX4465/MAX4467/MAX4469) 600kHz Av ≥ 5 (MAX4466/MAX4468)
- Available in Space-Saving Packages 5-Pin SC70 (MAX4465/MAX4466) 8-Pin SOT23 (MAX4467/MAX4468/MAX4469)
Applications
- - Microphone Preamplifiers - Hearing Aids - Cellular Phones - Voice-Recognition Systems - Digital Dictation Devices - Headsets - Portable Computing
