In this circuit, A1 is used to improve the dc characteristics of A2, which, in turn, determines the bandwidth of A3. Using an OP-07 for A1, an AH0014 for A2, and an AH0010 for A3, the circuit is capable of driving a 51-Ω load at±5 V to 10 MHz. Drift is less than 1μV/℃ with an offset of 20 μV. Figure 3-48B shows the external connections for the AH0014.
