TSU104

Nanopower (580nA) rail-to-rail I/O 5V CMOS Op-Amp

快速浏览资源

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.

Key Features
