Feature Description (continued)

7.2.5 High-gain Sallen-key Active Filters

The LMH6624 and LMH6626 devices are well suited for high gain Sallen-Key type of active filters. Figure 53

Application Note OA-21, Component Pre-Distortion for Sallen Key Filters (SNOA369) will enable the proper

selection of components for these high-frequency filters.

7.2.6 Low Noise Magnetic Media Equalizer

The LMH6624 and LMH6626 devices implement a high-performance low noise equalizer for such application as

magnetic tape channels as shown in Figure 54. The circuit combines an integrator with a bandpass filter to

produce the low noise equalization. The circuit’s simulated frequency response is illustrated in Figure 55.
