Rail-to-rail input and output  
Description  
The TSU111 operational amplifier (op amp)  
offers an ultra low-power consumption of 900 nA  
typical and 1.2 µA maximum when supplied by  
3.3 V. Combined with a supply voltage range of  
1.5 V to 5.5 V, these features allow the TSU111  
to be efficiently supplied by a coin type Lithium  
battery or a regulated voltage in low-power  
applications.  
Gain bandwidth product: 11.5 kHz typ  
Low input bias current: 10 pA max at 25 °C  
High tolerance to ESD: 4 kV HBM  
Benefits  
The high accuracy of 150 µV max and 11.5 kHz  
gain bandwidth make the TSU111 ideal for  
sensor signal conditioning, battery supplied, and  
portable applications.  
More than 25 years of typical equivalent  
lifetime supplied by a 220 mA.h CR2032  
coin type Lithium battery  
High accuracy without calibration  
Tolerance to power supply transient drops
