sensors
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.
