AD8655 & AD8656 Precision CMOS Amplifiers

Analog Devices Inc. AD8655 and AD8656 Precision CMOS Amplifiers leverage ADI's DigiTrim® technology to achieve low noise and high DC accuracy. DigiTrim technology is a method of trimming the offset voltage of the amplifier after it is packaged. The advantage of post-package trimming is that it corrects any offset voltages caused by the mechanical stresses of assembly. The AD8655 and AD8656 are available in standard op-amp pinouts, making DigiTrim completely transparent to the user. The input stage of the amplifiers features a true rail-to-rail architecture, allowing the input common-mode voltage range of the amplifiers to extend to both positive and negative supply rails. The open-loop gain of the AD8655 and AD8656 with a load of 10kΩ is typically 110dB.
