NOTES: A. R1, R2, R3, and R4 are used only if gain adjustment is required. See table in Figure 3 for recommended values. Adjust R1 for
VOA = 0 V with code 10000000 in DACA latch. Adjust R3 for VOB = 0 V with 10000000 in DACB latch.
B. Matching and tracking are essential for resistor pairs R6, R7, R9, and R10.
C. C1 and C2 phase compensation capacitors (10 pF to 15 pF) may be required if A1 and A3 are high-speed amplifiers.
