The digitally programmable gain amplifier shown in Figure 38
has 12-bit gain resolution with 10-bit gain linearity over the
range of 1 to 1024. The low bias current of the OP97 main-
tains this linearity, while C1 limits the noise voltage bandwidth,
allowing accurate measurement down to microvolt levels.

Many high speed amplifiers suffer from less-than-perfect low
frequency performance. A combination amplifier consisting of
a high precision, slow device like the OP97 and a faster device such
as the AD8610 results in uniformly accurate performance from
dc to the high frequency limit of the AD8610, which has a gain-
bandwidth product of 25 MHz. The circuit shown in Figure 39
accomplishes this, with the AD8610 providing high frequency
amplification and the OP97 operating on low frequency signals
and providing offset correction. Offset voltage and drift of the
circuit are controlled by the OP97.
