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. 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
