Assuming the position of the industry's lowest noise auto-zero amp, the AD8628 provides a noise figure of 0.5 µVp-p from 0 Hz to 10 Hz. Commonly called a chopper-stabilized amplifier, the device has a maximum offset voltage of 5 µV and a maximum input offset drift of less than 0.02 µV/¡C. Other features include single-supply operation from 2.7V to 5V, a rail-to-rail input and output swing, and an input bias current of 30 pA. Available in a SOT-23 or eight-pin SOIC package, the device does not require any external capacitors and operates in temperatures from -40ûC to +125ûC. Pricing is $1.25 each/1,000.
