Description
The TSV911/2/4 family of single, dual & quad
operational amplifiers offers low voltage operation
and rail-to-rail input and output.
This family features an excellent speed/power
consumption ratio, offering an 8MHz gain-
bandwidth product while consuming only 1.1mA
max at 5V supply voltage. These op-amps are
unity gain stable for capacitive loads up to 200pF.
They also feature an ultra-low input bias current.
These characteristics make the TSV911/2/4
family ideal for sensor interfaces, battery-supplied
and portable applications, as well as active
filtering.
