Analog Devices Inc./Maxim Integrated MAX4613EPE+

Overview

MAX4613EPE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in ±4.5V to ±20V or +4.5V to +40V supply systems. It delivers 85Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and rail-to-rail analog signal handling up to ±15V - enabling high-fidelity audio routing and low-distortion sample-and-hold circuits.

For engineers reviewing the MAX4613EPE+ datasheet, MAX4613EPE+ pinout, MAX4613EPE+ application, or MAX4613EPE+ equivalent, key selection criteria include guaranteed R_ON matching (≤4Ω), on-resistance flatness (≤9Ω), ESD tolerance (≥2000V), TTL/CMOS logic compatibility, and -40°C to +85°C industrial temperature operation.

Technical Context

The MAX4613EPE+ implements four independent SPST switches with complementary logic control: IN1–IN4 directly drive respective S–D paths, where IN=LOW activates NC switches (S1/D1, S2/D2) and IN=HIGH activates NO switches (S3/D3, S4/D4). Its CMOS process ensures symmetrical conduction and bidirectional signal flow without polarity dependence.

It supports both bipolar (±4.5V to ±20V) and single-supply (+4.5V to +40V) operation, with VL pin configurable for TTL (5V) or CMOS (V+) logic thresholds. Switching performance is characterized by t_ON < 250ns and t_OFF < 70ns at ±10V supplies, while break-before-make timing is tightly controlled at 5–20ns to prevent transient shorting.

FAQ

What is the maximum analog signal voltage range supported by the MAX4613EPE+?

The MAX4613EPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V. Under specified operating conditions, it handles ±15V signals with guaranteed performance, and its analog signal range is ±15V at ±15V supplies or 0V to +12V with +12V single supply. This makes MAX4613EPE+ suitable for high-dynamic-range audio and industrial sensor interfaces where full supply swing utilization is critical.

Does the MAX4613EPE+ require external level-shifting for TTL-compatible logic inputs?

No - the MAX4613EPE+ includes a dedicated VL pin that accepts either 5V (for TTL compatibility) or V+ (for CMOS compatibility), eliminating the need for external level shifters. When VL = 5V, the device recognizes VINH ≥ 2.4V and VINL ≤ 0.8V, matching standard TTL thresholds. This feature simplifies interface design in mixed-voltage systems and ensures reliable operation with legacy microcontrollers, which is especially valuable in deployed MAX4613EPE+ installations.

How does the MAX4613EPE+ achieve low charge injection, and why is this important?

The MAX4613EPE+ achieves ≤10pC max charge injection through matched transistor geometry and optimized gate drive timing, minimizing transient voltage spikes during switching. This is critical in sample-and-hold circuits and precision ADC front-ends, where injected charge causes hold-mode errors and degrades effective resolution. For example, with a 1nF hold capacitor, 10pC injection yields only 10mV glitch - enabling stable 14-bit+ acquisition in MAX4613EPE+-based data loggers.

Can the MAX4613EPE+ operate with unbalanced supplies like +24V and -5V?

Yes - the MAX4613EPE+ explicitly supports unbalanced supplies such as +24V and -5V, as confirmed in its Applications Information section. The device requires only that |V+ − V−| ≤ +44V and that each supply remains within its absolute maximum rating. This capability allows MAX4613EPE+ to interface seamlessly with asymmetric power domains in telecom line cards and industrial PLC I/O modules without additional regulation.

What is the significance of the exposed substrate connection on Pin 13 (V+) of the MAX4613EPE+ DIP package?

Pin 13 (V+) in the MAX4613EPE+ DIP package connects directly to the silicon substrate, serving as both the positive supply and the substrate bias node. This configuration stabilizes the body potential of internal MOSFETs, minimizing threshold voltage drift and ensuring consistent R_DS(ON) across temperature. Proper connection of V+ is mandatory - floating or reverse-biased V+ risks latch-up or parametric shift, so MAX4613EPE+ designs must tie Pin 13 to the highest positive rail without series impedance.
