MAX4805A Datasheet Low-noise Operational Amplifiers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX4805/MAX4805A Octal High-Voltage-Protected, Low-Power, Low-Noise Operational Amplifiers.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX4805/MAX4805A are octal high-voltage-protected operational amplifiers.

These devices are a fully integrated, very compact solution for in-probe amplification of echo signals coming from transducers in an ultrasound system.

The use of in-probe buffering improves system signal-to-noise ratio (SNR) for transducers featuring high-output impedance.

Key Features

  • 44MHz (typ) -3dB bandwidth and very low voltage and current noise, ensuring excellent noise figure. The output signals of these operational amplifiers are limited with diodes in an antiparallel configuration to GND. The MAX4805/MAX4805A provide HV protection for inputs and outputs of the operational amplifiers. The operational amplifiers inputs are protected by an exter- nal HV capacitor. An Finutengrcattedioanutaoml aDticiahgighr-avomltasge switch protects the output of the amplifier from HV bu.
