Description

The TSV620, TSV620A, TSV621, and TSV621A

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

suit battery-powered devices and extend their

battery life.

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 present high tolerance to ESD,

sustaining 4 kV for the human body model.

The device is 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, TSV620A,

TSV621, and TSV621A ideal for sensor

interfaces, battery-supplied and portable

applications, as well as active filtering.
