19-1136; Rev 6; 7/07 Quad, Low-Voltage, SPST Analog Switches Features The MAX4521/MAX4522/MAX4523 are quad, low-voltage, single-pole/single-throw (SPST) analog switches. On-resistance (100Ω max) is matched between switches to 4Ω max, and is flat (12Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C. ♦ +2V to +12V Single Supply ±2V to ±6V Dual Supplies The MAX4521 has four normally closed (NC) switches, and the MAX4522 has four normally open (NO) switches. The MAX4523 has two NC switches and two NO switches. These CMOS switches can operate with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. They are fully specified for single +2.7V operation. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply. ♦ Rail-to-Rail Signal Handling ♦ 100Ω Signal Paths with ±5V Supplies ♦ Low Power Consumption, <1µW ♦ 4 Separately Controlled SPST Switches ♦ Pin Compatible with Industry-Standard DG211/DG212/DG213 ♦ >2kV ESD Protection per Method 3015.7 ♦ TTL/CMOS-Compatible Inputs with ±5V or Single +5V Supply Ordering Information Applications PART TEMP RANGE PINPACKAGE PKG CODE MAX4521CPE 0°C to +70°C 16 Plastic DIP P16-1 Battery-Operated Equipment MAX4521CSE 0°C to +70°C 16 Narrow SO S16-2 Data Acquisition MAX4521CEE 0°C to +70°C 16 QSOP E16-4 Test Equipment MAX4521CUE 0°C to +70°C 16 TSSOP U16-2 Avionics MAX4521CGE 0°C to +70°C 16 QFN-EP** MAX4521C/D 0°C to +70°C Dice* Audio Signal Routing G1644-1 — Ordering Information continued at end of data sheet. *Contact factory for dice specifications. **EP = Exposed pad.

They have three supply pins: V+, V-, and GND. V+ and V- are used to drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESDprotection diodes are internally connected between each analog-signal pin and both V+ and V-. If any analog signal exceeds V+ or V-, one of these diodes conducts. During normal operation these reverse-biased ESD diodes leak, forming the only current drawn from V+ or V-. Virtually all the analog leakage current is through the ESD diodes. 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 the same or opposite polarity. There is no connection between the analog-signal paths and GND. The analog-signal paths consist of an N-channel 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 translators, and set the input logic thresholds. The logic-level translators convert the logic levels to switched V+ and V- signals to drive the gates of the analog switches. This drive signal is the only connection between the logic supplies and the analog supplies. V+ and V- have ESD-protection diodes to GND. The logic-level inputs and output have ESD protection to V+ and to GND. Increasing V- has no effect on the logic-level thresholds, but it does increase the drive to the P-channel switches, reducing their on-resistance. V- also sets the negative limit of the analog-signal voltage. 8 The logic-level thresholds are CMOS/TTL compatible when V+ = +5V. The threshold increases slightly as V+ is raised, and when V+ reaches +12V, the level threshold is about 3.1V. This is above the TTL output highlevel minimum of 2.8V, but still compatible with CMOS outputs. Bipolar Supplies The MAX4521/MAX4522/MAX4523 operate with bipolar supplies between ±2V and ±6V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 13.0V. Do not connect the MAX4521/MAX4522/MAX4523 V+ to +3V, and then connect the logic-level-input pins to TTL logic-level signals. TTL logic-level outputs in excess of the absolute maximum ratings can damage the part and/or external circuits. Caution: The absolute maximum V+ to V- differential voltage is 13.0V. Typical ±6V or 12V supplies with ±10% tolerances can be as high as 13.2V. This voltage can damage the MAX4521/MAX4522/MAX4523. Even ±5% tolerance supplies may have overshoot or noise spikes that exceed 13.0V. Single Supply The MAX4521/MAX4522/MAX4523 operate from a single supply between +2V and +12V when V- is connected to GND. All of the bipolar precautions must be observed. High-Frequency Performance In 50Ω systems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics). Above 20MHz, the on-response has several minor peaks that are highly layout dependent. The problem with high-frequency operation is not turning the switch on, but turning it off. The off-state switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off-isolation is about -52dB in 50Ω systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off-isolation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is due entirely to capacitive coupling. _______________________________________________________________________________________ Quad, Low-Voltage, SPST Analog Switches MAX4521 MAX4522 MAX4523 SWITCH INPUT V+ SWITCH OUTPUT V+ NO or NC COM V COM VOUT RL 300Ω IN, EN GND LOGIC INPUT LOGIC INPUT 50% 0 CL 35pF t OFF VOUT VSWITCH OUTPUT V- 0 0 ( 0.9 x V0UT 0.9 x VOUT t ON CL INCLUDES FIXTURE AND STRAY CAPACITANCE.
