38V, Low-Noise, MOS-Input,  
Low-Power Op Amp  
MAX945  
General Description  
Features  
The MAX9945 operational amplifier features an excellent  
combination of low operating power and low input volt-  
age 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 cur-  
rent. The MAX9945 is unity-gain stable and is capable of  
rail-to-rail output voltage swing.  
+4.75V to +38V Single-Supply Voltage Range  
±±.4V to ±ꢀꢁV ꢂual-Supply Voltage Range  
Rail-to-Rail Output Voltage Swing  
400µA Low Quiescent Current  
50fA Low Input Bias Current  
ꢀfA/Hz Low Input Current Noise  
ꢀ5nV/Hz Low Noise  
The MAX9945 is ideal for portable medical and industri-  
al applications that require low noise analog front-ends  
for performance applications such as photodiode trans-  
impedance and chemical sensor interface circuits.  
3MHz Unity-Gain Bandwidth  
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).  
Wide Temperature Range from -40°C to +ꢀ±5°C
