The ISL28133 is a single micropower, chopper stabilized  
operational amplifier that is optimized for single supply  
operation from 1.65V to 5.5V. Its low supply current of  
18µA and wide input range enable the ISL28133 to be an  
excellent general purpose op amp for a range of  
applications. The ISL28133 is ideal for handheld devices  
that operates off 2 AA or single Li-ion batteries.  
• Low Noise (0.01Hz to 10Hz). . . . . . .1.1µV , Typ.  
P-P  
The ISL28133 is available in the 5 Ld SOT-23, the 5 Ld  
SC70 and the 6 Ld 1.6mmx1.6mm µTDFN packages. All  
devices operates over the extended temperature range  
of -40°C to +125°C.  
• Rail-to-Rail Inputs and Output  
• Operating Temperature Range . . -40°C to +125°C  
Applications*(see page 17)  
• Bidirectional Current Sense  
Temperature Measurement  
• Medical Equipment  
• Electronic Weigh Scales
