Description
The TSV91x and TSV91xA operational amplifiers (op amps) offer low voltage
operation and rail-to-rail input and output, as well as an excellent speed/power
consumption ratio, providing an 8 MHz gain-bandwidth product while consuming only
1.1 mA maximum at 5 V. The op amps are unity gain stable and feature an ultra-low
input bias current.
The devices are ideal for sensor interfaces, battery-supplied and portable
applications, as well as active filtering.

7. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
8. Machine model: 200 pF charged to the specified voltage, then discharged directly between two pins of the device with no
external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating
9. Charged device model: all pins plus packages are charged together to the specified voltage and then discharged directly to
the ground.
