MAX4526ESA+

The MAX4526/MAX4527 are phase-reversal analog switches, consisting of two normally open and two normally closed CMOS analog switches arranged in a bridge configuration. Analog signals are put into two input pins and taken out of two output pins. A logiclevel signal controls whether the input signal is routed through normally or inverted. A low-resistance DC path goes from inputs to outputs at all times, yet isolation between the two signal paths is excellent. Analog signals range from V- to V+. These parts are characterized and optimized with ±15V supplies, and they can operate from a single supply. The MAX4526 is optimized for high-frequency operation, and has a higher-speed logic-level translator and switch driver. The MAX4527 has identical analog switch characteristics, but has a slower logic-level translator and switch driver for lower current consumption. The MAX4526/MAX4527 are designed for DC and lowfrequency-signal phase-reversal applications, such as chopper amplifiers, modulator/demodulators, and selfzeroing or self-calibrating circuits. Unlike conventional CMOS switches externally wired in a bridge configuration, both DC and AC symmetry are optimized with a small 8-pin configuration.
