100MHz gain bandwidth (GBW) precision CMOS operational amplifier

The single OPAx620

is a high-speed, voltage-feedback operational amplifier designed for current sensing and

precision applications. Offering unity-gain stability and high output current drive, the OPAx620 delivers enhanced signal-chain precision across temperature,

exceeding the performance of conventional wide-bandwidth CMOS amplifiers. Operating with a

low quiescent current of 5.1mA per channel, the OPAx620 is suitable

for power-sensitive applications.

The OPAx620

operates from a single or dual supply voltage ranging from 2.5V (±1.25V) to 5.5V (±2.75V).

It features a wide common-mode input range extending beyond the supply rails, and delivers a

rail-to-rail output swing within 30mV of the positive and negative supplies, enabling a wide

dynamic range.

The OPAx620 is available in a small 5-pin SOT-23 package and is specified for operation

over an extended temperature range of –40°C to +125°C.
