STMicroelectronics | TSV621AICT

The operational amplifier is arguably the most useful single device in analog electronic circuitry. With only a handful of external components, it can be made to perform a wide variety of analog signal processing tasks. It is also quite affordable. Op-amps are often referred to as the workhorse of the analog design world

Future offers one of the widest selections of operational amplifiers (op amps) in the industry. Our offering encompasses, current-sense amplifiers, and comparators for audio and video applications, battery and power management, and signal conditioning.

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.

All these features make the TSV621 ideal for the below applications:

• Battery-powered applications
• Portable devices
• Signal conditioning
• Active filtering
• Medical instrumentation

The TSV621AICT is available in a SC70-5 micropackages, with an extended temperature range of -40 to +125° and a low input offset voltage of max 800 µV.
