Description

The TSV620 and TSV621 are single operational amplifiers offering low voltage, low power operation and rail-to-rail input and output.

With a very low input bias current and low offset voltage (800 µV maximum for the A version), the TSV62x is ideal for applications requiring precision. The device can operate at a power supply ranging from 1.5 to 5.5 V, and therefore suits battery-powered devices and extends their battery life.

TSV620ICT/ILT

SC70-6/SOT23-6

This product features an excellent speed/power consumption ratio, offering a 420 kHz gain bandwidth while consuming only 29 µA at a

5 V supply voltage.

These operational amplifiers are unity gain stable for capacitive loads up to 100 pF.

The device is internally adjusted to provide very narrow dispersion of AC and DC parameters, especially power consumption, product gain bandwidth and slew rate.

The TSV62x presents a high tolerance to ESD, sustaining 4 kV for the human body model.

The devices are offered in macropackages, SC70-6 and SOT23-6 for the TSV620 and SC70-5 and SOT23-5 for the TSV621. They are guaranteed for industrial temperature ranges from -40° C to +125° C.

All these features make the TSV620 and TSV621 ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

1.All voltage values, except differential voltage are with respect to network ground terminal.

2.Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3.Vcc-Vin must not exceed 6 V.

4.Input current must be limited by a resistor in series with the inputs.

5.Vcc-SHDN must not exceed 6 V.

6.Short-circuits can cause excessive heating and destructive dissipation.

7.Rth are typical values.

8.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.

9.Machine mode: a 200 pF capacitor is 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.

10.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
