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.
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.
