What is a rail to rail amplifier?

Analog Devices High Speed ​​Optics (> 50 MHz) Analog Devices Rail-to-rail assemblies allow you to work with lower supply voltages, approach the tracks and provide a wider dynamic range.

Equipped with a portfolio with a wide range of op-amp, which includes both railway entry / exit and rail / rail production, ADI offers the widest range of high-end products available on the market. Whether it’s broadband, low speed or reduced distortion or railroad tracking, no one imposes more performance standards for next-generation models than analog devices.

Ads for single-source operational amplifiers often require railroad track output. What does this statement really mean? The first page of the data sheet of one of the single-source power supplies can appeal to the bullet or the “incoming / outgoing” bullet; keep reading because if you’re looking for an amplifier with only one power source whose output can be driven up to one power rail and / or the other, good luck. What should you know about the performance of an amplifier that claims to exit from the track to the track?

Two amplifier specifications will help you solve this problem: output voltage output and open circuit voltage gain.

Starting the output voltage of an optical amplifier defines to what extent the amplifier output can be driven on the positive or negative supply line. Test conditions for high voltage (VOH) and low voltage (VOL) output tangential tests typically lead the amplifier out of its linear region. Open Loop Amplifier (AVOL) specifications are primarily the ratio of output voltage variation to output voltage as the input voltage offset voltage changes, but also provide output linearity indices under test conditions.
