19-1165; Rev 0; 12/96 Phase-Reversal Analog Switches The MAX4526/MAX4527 are CMOS analog ICs configured as phase-reversal switches. The MAX4526 is optimized for high-speed applications, such as chopper amplifiers, while the MAX4527 is optimized for low-power applications. The MAX4526/MAX4527 operate from a +4.5V to +36V single supply or ±4.5V to ±18V dual supplies. On-resistance (175Ω max) is matched between switches to 8Ω maximum. Each switch can handle rail-to-rail analog signals. Maximum leakage current is only 0.5nA at +25°C and 10nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility. ____________________________Features ♦ 10pC (max) Charge Injection ♦ 2pC (max) Charge-Injection Match ♦ 175Ω Signal Paths with ±15V Supplies ♦ Guaranteed Break-Before-Make ♦ Rail-to-Rail Signal Handling ♦ Transition Time < 100ns with ±15V Supplies ♦ 1µA Current Consumption (MAX4527) ♦ >2kV ESD Protection per Method 3015.7 ♦ TTL/CMOS-Compatible Inputs ♦ Available in Small, 8-Pin µMAX Package ______________Ordering Information ________________________Applications Chopper-Stabilized Amplifiers Balanced Modulators/Demodulators Data Acquisition Test Equipment Audio-Signal Routing PART TEMP.

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 that allows simple board layout and isolation of logic signals from analog signals. FUNCTION Positive Analog/Digital Supply-Voltage Input. Internally connected to substrate. Note: A, B, X and Y pins are identical and interchangeable. Either may be considered as an input or output; signals pass equally well in either direction. However, AC symmetry is best when A and B are the input, and X and Y are the output. Reduce AC balance in critical applications by using A and X or A and Y as the input, and B and Y or B and X as the output.

Typical Application Circuits 6 _______________________________________________________________________________________ OUTPUTS Phase-Reversal Analog Switches Overview The MAX4526/MAX4527 construction is typical of most CMOS analog switches. It has three supply pins: V+, V-, and GND. V+ and V- drive the internal CMOS switches and set the analog-voltage limits on any switch. Reverse ESD-protection diodes are internally connected between each analog signal pin, and both V+ and V-. One of these diodes conducts if any analog signal exceeds V+ or V-. Virtually all of the analog leakage current is through the ESD diodes to V+ or V-. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages vary as the signal varies. The difference in the two diode leakages from the signal path to the V+ and V- pins constitutes the analog-signal-path leakage current. All analog leakage current flows to the supply terminals, not to the other switch terminal. This explains how both sides of a given switch can show leakage currents of either the same or opposite polarity. There is no connection between the analog-signal paths and GND. The analog-signal paths consist of an Nchannel and P-channel MOSFET with their sources and drains paralleled and their gates driven out-of-phase to V+ and V- by the logic-level translators. V+ and GND power the internal logic and logic-level translator and set the input logic threshold. The logiclevel translator converts the logic levels to switched V+ and V- signals to drive the analog switches’ gates. This drive signal is the only connection between GND and the analog supplies. V+ and V- have ESD-protection diodes to GND. The logic-level input has ESD protection to V+ and to V- but not to GND, so the logic signal can go below GND (as low as V-) when bipolar supplies are used. Increasing V- has no effect on the logic-level thresholds, but it does increase the drive to the internal P-channel switches, reducing the overall switch on-resistance. Valso sets the negative limit of the analog-signal voltage. The logic-level input pin, IN, has ESD-protection diodes to V+ and V- but not to GND, so it can be safely driven to V+ and V-. The logic-level threshold, VIN, is CMOS/ TTL compatible when V+ is between 4.5V and 36V (see Typical Operating Characteristics). Bipolar Supplies The MAX4526/MAX4527 operate with bipolar supplies between ±4.5V and ±18V. However, since all factory characterization is done with ±15V supplies, specifications at other supplies are not guaranteed. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 44V (see Absolute Maximum Ratings).

Observe all of the bipolar precautions when operating from a single supply. __________Applications Information The MAX4526/MAX4527 are designed for DC and low-frequency-signal phase-reversal applications. Both DC and AC symmetry are optimized for use with ±15V supplies. Signal Phase/Polarity Reversal The MAX4526/MAX4527 can reverse the phase or polarity of a pair of signals that are out-of-phase and balanced to ground. This is done by routing signals through the MAX4526/MAX4527 and under control of the IN pin, reversing the two signals paths inside the switch before sending out to a balanced output. Figure 1 shows a typical example. The MAX4526/MAX4527 cannot reverse the phase or polarity of a singlegrounded signal, as can be done with an inverting op amp or transformer. Balanced Modulators/Demodulators The MAX4526/MAX4527 can be used as a balanced modulator/demodulator at carrier frequencies up to 100kHz (Figure 2). Higher frequencies are possible, but as frequency increases, small imbalances in the MAX4526/MAX4527’s internal capacitance and resistance gradually impair performance. Similarly, imbalances in external circuit capacitance and resistance to GND reduce overall carrier suppression. The carrier is applied as a logic-level square wave to IN. (Note that this voltage can go as negative as V-.) For best carrier suppression, the power-supply voltages should be equal, the square wave should have a precise 50% duty cycle, and both the input and output signals should be symmetrical about ground. Bypass V+ and V- to GND with 0.1µF ceramic capacitors, as close to the IC pins as possible. Since the logic-level translator/driver in the MAX4526 is faster than the one in the MAX4527, it gives better results at higher frequencies. In critical applications, carrier suppression can be optimized by trimming duty cycle, DC bias around GND, or external source and load capacitance. In signal lines, balancing both capacitance and resistance to GND produces the best carrier suppression. Transformer coupling of input and output signals provides the best isolation and carrier suppression. Transformers can also provide signal filtering, impedance matching, or low-noise voltage gain. Use a center-tapped transformer or high-resistance voltage divider to provide a DC path to GND on either the input signal or output signal. This ensures a DC path to GND and symmetrical operation of the internal switches. ______________________________________________Test Circuits/Timing Diagrams V+ VIN IN V+ V+ A -10V B +10V 50% VIN 0V 50Ω MAX4526 MAX4527 X GND V- VB VOUT 300Ω 35pF 90% VOUT 0V V- 90% VA tTRANS V- IS CONNECTED TO GND (0V) FOR SINGLE-SUPPLY OPERATION.
