Description

General part information

MAX9945 Series

The MAX9945 operational amplifier features an excellent combination of low operating power and low input voltage noise. In addition, MOS inputs enable the MAX9945 to feature low input bias currents and low input current noise. The device accepts a wide supply voltage range from 4.75V to 38V and draws a low 400µA quiescent current. The MAX9945 is unity-gain stable and is capable of rail-to-rail output voltage swing.The MAX9945 is ideal for portable medical and industrial applications that require low noise analog front-ends for performance applications such as photodiode transimpedance and chemical sensor interface circuits.The MAX9945 is available in both an 8-pin µMAX® and a space-saving, 6-pin TDFN package, and is specified over the automotive operating temperature range (-40°C to +125°C).ApplicationsActive Filters and Signal ProcessingAutomatic Test Equipment (ATE)Chemical Sensor InterfaceDisplays: Industrial, Front Panel, and InstrumentationHigh-Performance Audio Line OutIndustrial Sensors and InstrumentationIndustrial: Process Measurement and ControlMedical Pulse OximetryPanel MetersPhotodiode Sensor InterfacePower MetersProgrammable Logic Controllers (PLCs)
