Figure 5 shows the test circuit. Series capacitors and resistors

connected to the output of the op amp represent the load of the

LCD panel. The 300

Ω and 3 kΩ feedback resistors are used to

improve settling time. This test circuit simulates the worst-case

a scope photo of the instantaneous output peak current capability

of the AD856x family.
