... SOIC-14 EL5444CN PDIP-14 EL5144C Series Comparator Application The EL5144C series amplifier can be used as a very fast, single supply comparator. Most op amps used as a com- parator allow only slow speed operation because of output saturation issues. The EL5144C series amplifier doesn’t suffer from output saturation issues. Figure 3 shows the amplifier implemented as a comparator ...
