Analog Devices Inc./Maxim Integrated MAX4695EUB+T

Overview

The MAX4695EUB+T from Maxim Integrated is a low-voltage, dual SPDT analog switch operating from a single +1.8V to +5.5V supply, delivering 60Ω (max) on-resistance at +2.7V, 30ns turn-on time, and rail-to-rail signal handling - ideal for audio routing and battery-powered portable equipment.

For engineers reviewing the MAX4695EUB+T datasheet, MAX4695EUB+T pinout, MAX4695EUB+T application, or MAX4695EUB+T equivalent, key selection criteria include guaranteed R_ON matching (≤3Ω), low charge injection (4pC), −82dB crosstalk at 1MHz, and 1.8V logic compatibility with +2.7V to +3.3V supplies.

Technical Context

The MAX4695EUB+T implements two independent break-before-make SPDT switches with CMOS control inputs. Each switch supports bidirectional analog signal flow across the full supply range (GND to V+), with guaranteed R_ON flatness ≤10Ω and matching ≤3Ω between channels at +2.7V.

It features low dynamic distortion (THD = 0.03%), >300MHz −3dB bandwidth, and robust isolation (−75dB off-isolation, −82dB crosstalk at 1MHz), enabling high-fidelity signal routing in compact, low-power systems without external level-shifting.

FAQ

What is the maximum supply voltage rating for the MAX4695EUB+T?

The MAX4695EUB+T has an absolute maximum supply voltage (V+) of +6V. Operation beyond this limit risks permanent damage. The recommended operating range is +1.8V to +5.5V. At +5.5V, R_ON drops to 40Ω (max), and t_ON/t_OFF improve to 25ns/15ns - confirming that the MAX4695EUB+T delivers better dynamic performance at higher supplies while maintaining safe margins.

Does the MAX4695EUB+T support bidirectional analog signal flow?

Yes, the MAX4695EUB+T supports fully bidirectional analog signal routing on all COM_, NO_, and NC_ pins. Its CMOS-based switch architecture imposes no directionality constraint - signals can pass from COM to NO/NC or vice versa with identical R_ON, flatness, and THD. This makes the MAX4695EUB+T suitable for both source-selection and load-driving configurations in the same design.

How does the MAX4695EUB+T achieve 1.8V logic compatibility?

The MAX4695EUB+T achieves 1.8V logic compatibility through internally scaled input threshold voltages: VIH = +1.4V (min) and VIL = +0.5V (max) when powered from +2.7V to +3.3V. This allows direct connection to 1.8V-output microcontrollers without level shifters. The MAX4695EUB+T maintains these thresholds across temperature (−40°C to +85°C), ensuring reliable switching in portable environments.

What is the thermal performance of the MAX4695EUB+T in its µMAX package?

The MAX4695EUB+T in the 10-pin µMAX package has a thermal resistance θ_JA of 213°C/W (typical). At maximum continuous power dissipation (330mW at +70°C ambient), junction temperature rise is ~70°C - well within the −40°C to +85°C operating range. Derating begins above +70°C at 4.7mW/°C, supporting reliable operation in sealed enclosures or stacked PCBs where airflow is limited.

Can the MAX4695EUB+T replace mechanical relays in low-voltage applications?

Yes, the MAX4695EUB+T is explicitly designed for relay replacement in low-voltage applications such as battery-operated test equipment and portable medical devices. With 60Ω R_ON, <1nA leakage, and no moving parts, it eliminates bounce, wear-out, and EMI issues associated with electromechanical relays - while enabling microsecond-scale switching and integration into ASIC-like signal chains. The MAX4695EUB+T's small µMAX footprint further accelerates board-level miniaturization.
