One other major advantage of these devices lie in their rail-to-rail voltage operation for maximum range. The devices also provide a typical gain bandwidth product of 11kHz and are also unity gain stable. The devices are available in a range of packages according the number of internal amplifiers. The special characteristics of these devices will ensure their excellent use in applications with stringent low power demands such as portable products, battery powered equipment, low power sensor signal processing etc. Selection Table Part No. HT9291 HT9292 HT9294 Amplifiers 1 2 4 Package TSOT23-5 8DIP/SOP 14DIP/SOP Block Diagram 1 O U T 1 IN 1 IN + V D D 2 IN + 2 IN 2 O U T 4 O U T 4 IN 4 IN + V S S 3 IN + 3 IN 3 O U T Rev. 1.10 1...
