Description

The TSV911/2/4 family of single, dual and quad operational amplifiers offe rs low v oltage operation and rail-to-rail input and output.

This family features an excellent speed/power consumption ratio, offering an 8 MHz gainbandwidth product while consuming only 1.1 mA max at 5 V supply voltage. These op-amps are unity gain stable f or capacitiv e loads up to 200 pF. They also feature an ultra-low input bias current.

These characteristics make the TSV911/2/4 family ideal for sensor interfaces, batt ery-supplied and portable applications, as well as active filtering.

6. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a

1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.

7. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between

two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating.

8. Charged device model: all pins and the package are charged together to the specified voltage and then

discharged directly to the ground through only one pin. This is done for all pins.
