Analog Devices Inc./Maxim Integrated MAX4663CPE+

Overview

MAX4663CPE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, 2.5Ω max on-resistance, guaranteed break-before-make switching, and rail-to-rail signal handling up to ±20V dual supply or +36V single supply. It serves as a solid-state replacement for reed relays in test equipment and data acquisition systems requiring low distortion and high reliability.

For engineers reviewing the MAX4663CPE+ datasheet, MAX4663CPE+ pinout, MAX4663CPE+ application, or MAX4663CPE+ equivalent, key selection criteria include verified break-before-make timing (5–125 ns), R_ON matching (≤0.5Ω), off-leakage (<0.5 nA at +85°C), and TTL/CMOS-compatible logic control across full supply range.

Technical Context

The MAX4663CPE+ implements a CMOS-based quad SPST architecture with independent NO/NC channel pairing per switch pair (SW1/SW4 = NO; SW2/SW3 = NC), enabling simultaneous bidirectional signal routing with guaranteed break-before-make transition to prevent momentary shorting. Its dual-supply operation (±4.5V to ±20V) and single-supply mode (+4.5V to +36V) are supported by a dedicated VL pin for logic-level independence.

On-resistance flatness (≤0.7Ω over ±10V signal range) and channel-to-channel R_ON match (≤0.4Ω typ) ensure minimal gain error and crosstalk in precision multiplexing. Dynamic performance includes 500 ns max turn-on time, 350 ns max turn-off time, and 20 pC typical charge injection - critical for sample-and-hold and ADC front-end applications.

FAQ

What is the maximum supply voltage rating for MAX4663CPE+?

The MAX4663CPE+ supports a single analog supply from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but continuous operation must remain within the specified ranges to ensure reliability and parameter compliance. Exceeding these limits risks permanent damage.

Does MAX4663CPE+ support rail-to-rail analog signal switching?

Yes, MAX4663CPE+ supports true rail-to-rail analog signal handling - signals from V− to V+ pass unclipped through the switch channels. This capability is confirmed across both single-supply (e.g., V− = GND, V+ = +12V) and dual-supply (e.g., V+ = +15V, V− = −15V) configurations, making it suitable for op-amp output routing and wide-dynamic-range sensor interfaces.

What does "guaranteed break-before-make" mean for MAX4663CPE+?

Guaranteed break-before-make in MAX4663CPE+ means that during state transitions, the NC path opens *before* the NO path closes - verified with 5–125 ns minimum dead time. This prevents momentary shorting between signal paths, a critical requirement in fault-tolerant multiplexers, guarded measurements, and safety-critical routing where unintended signal coupling must be eliminated.

Can MAX4663CPE+ operate with a 3.3V logic supply?

Yes, MAX4663CPE+ accepts 3.3V logic inputs via its dedicated VL pin, which is independent of analog supply rails. With VL = 3.3V, the device recognizes VIN_H ≥ 2.4V and VIN_L ≤ 0.8V - fully compatible with standard 3.3V CMOS logic families while analog supplies operate at ±15V or +24V, enabling seamless integration into mixed-voltage systems.

What is the off-leakage current specification for MAX4663CPE+ at elevated temperature?

MAX4663CPE+ specifies off-leakage current (I_NO/I_NC) of ≤0.5 nA maximum at TA = +85°C, tested per Note 6 in the datasheet. This low leakage is critical for high-impedance applications such as electrometer-grade sensor interfaces and precision integrators, where even sub-nanoampere currents can introduce measurable offset or drift over time.
