Description

The TSV621 is a single operational amplifier

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

TSV621 is ideal for applications that require

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

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.

This operational amplifier is 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 TSV621 presents a high tolerance to ESD,

sustaining 4 kV for the human body model.

Additionally, the TSV621 is offered in SC70-5 and

SOT23-5 micropackages, with extended

temperature ranges from -40° C to +125° C.

All these features make the TSV621 ideal for

sensor interfaces, battery-supplied and portable

applications, as well as active filtering.
