Description

The TSU101, TSU102, and TSU104 operational

amplifiers offer an ultra low-power consumption of

580 nA typical and 750 nA maximum per channel

when supplied by 1.8 V. Combined with a supply

voltage range of 1.5 V to 5.5 V, these features

allow the TSU10x series to be efficiently supplied

by a coin type Lithium battery or a regulated

voltage in low-power applications.

The 8 kHz gain bandwidth of these devices make

them ideal for sensor signal conditioning, battery

supplied, and portable applications.
