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.
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.
