MAX4805A - Low-Noise Operational Amplifiers

This page provides the datasheet information for the MAX4805A, a member of the MAX4805 Low-Noise Operational Amplifiers family.

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.

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.

MAX4805/MAX4805A Octal High-Voltage-Protected, Low-Power, Low-Noise Operational Amplifiers 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. This results in greater penetration depth and sensitivity. The MAX4805/MAX4805A can be adopted in ultrasound probes without any change in the system (scanner machine).
