The TS94x op-amps are ideal for battery-powered  
systems, where very low supply current and  
output rail-to-rail are required. Their very low -  
1 pA typ input bias current and constant supply  
current over supply voltage enhance TS94x’s  
performance near the end of the battery charge or  
battery life.
