TSV621

Micro-power CMOS op-amp
  • active Active

The TSV621 is a single operational amplifier offering low voltage, low power operation and railto- 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.
