Figure 8. Noise without output loading, and with the the 1µF capacitor box connected, plus
typical offset. The noise, as measured with a true rms voltmeter in a 1MHz bandwidth, is
48µV with no load, and 18µV
rms
bandwidths of the amplifier are DC – 100kHz and DC – 500Hz. The noise and offset may
appear to be slightly higher than shown here if the amplifier input is not differentially
