BANDPASS FILTER
Figure 3 shows a single OPA2652 implementing a sixth-
order bandpass filter. This filter cascades two second-order
Sallen-Key sections with transmission zeros, and a double
real pole section. It has 0.3dB of ripple, –3dB frequencies of
450kHz and 11MHz, and –23dB frequencies of 315kHz and
16MHz. The 20.0
resistor isolates the first OPA2652 out-
put from capacitive loading. This improves stability with
minimal impact on the filter response. Figure 4 shows the
nominal response simulated by SPICE.

VIDEO LINE DRIVER
Figure 5 shows the OPA2652 used as a video line driver. Its
outstanding differential gain and phase allow it to be used in
studio equipment, while its low cost and SOT23-8 package
option will support consumer applications.
PULSE DELAY CIRCUIT
Figure 6 shows the OPA2652 used in a pulse delay circuit.
This circuit cascades the two op amps in the OPA2652, each
forming a single pole, active allpass filter. The overall gain
is +1, and the overall delay through the filter is:
