Analog Devices Inc./Maxim Integrated MAX4601EAE+T

Overview

MAX4601EAE+T from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max R_ON match between channels, and 2.5nA max off-leakage at +85°C, enabling low-distortion audio-signal routing and reed-relay replacement in automated test equipment.

For engineers reviewing the MAX4601EAE+T datasheet, MAX4601EAE+T pinout, MAX4601EAE+T application, or MAX4601EAE+T equivalent, key selection criteria include guaranteed R_ON flatness (0.5Ω max), ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, TTL/CMOS-compatible logic thresholds, and 16-pin SSOP packaging rated for -40°C to +85°C industrial temperature range.

Technical Context

The MAX4601EAE+T implements CMOS-based transmission-gate architecture with independent digital control inputs per channel, supporting true bidirectional analog signal flow. Its internal level-shifting circuitry ensures consistent switching behavior across full rail-to-rail input voltage ranges (V_COM = V_NO/V_NC = ±10V or 0–10V).

Each NC switch exhibits matched turn-on/turn-off timing (t_ON = 160ns typ, t_OFF = 190ns typ at V_COM = ±10V), low charge injection (20pC typ), and high off-isolation (-56dB typ at 1MHz), making it suitable for multiplexed data acquisition and precision sensor interface applications where signal integrity and channel crosstalk are critical.

FAQ

What is the operating temperature range for the MAX4601EAE+T?

The MAX4601EAE+T is specified for industrial operation from -40°C to +85°C. This range is validated per the device's qualification testing and applies to all electrical parameters in the datasheet, including on-resistance, leakage current, and switching times. The SSOP package's thermal characteristics support sustained operation within this envelope under typical PCB copper pour and airflow conditions. MAX4601EAE+T maintains full parameter compliance across the entire range without derating.

Does the MAX4601EAE+T support single-supply operation?

Yes, the MAX4601EAE+T operates from a single supply of +4.5V to +36V. In this mode, V− is connected to GND, V+ supplies the analog path, and VL is typically tied to +5V for TTL/CMOS compatibility. All specifications-including 2.5Ω max R_ON, 2.5nA max off-leakage, and rail-to-rail signal handling-are guaranteed under single-supply conditions. MAX4601EAE+T retains identical timing and matching performance as in dual-supply mode.

How does the MAX4601EAE+T differ from the MAX4602EAE+T?

The MAX4601EAE+T features four normally closed (NC) switches, while the MAX4602EAE+T provides four normally open (NO) switches. Their pinouts, supply requirements, R_ON, leakage, and timing specs are identical-but logic polarity is inverted: for MAX4601EAE+T, IN = 0 closes the switch, whereas for MAX4602EAE+T, IN = 1 closes it. MAX4601EAE+T is selected where fail-safe closed-path behavior is required, such as default signal pass-through in power-loss scenarios.

What is the maximum analog signal voltage the MAX4601EAE+T can handle?

The MAX4601EAE+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of V+ to GND ≤ +44V and V− to GND ≥ -44V. Under normal operation, signals up to ±10V are fully characterized for R_ON flatness, leakage, and distortion. The device clamps inputs exceeding V+/V− via internal diodes, but forward current must be limited externally to avoid damage. MAX4601EAE+T maintains 2.5Ω max R_ON across the full ±10V range.

Is the MAX4601EAE+T pin-compatible with other packages in the MAX460x family?

Yes, the MAX4601EAE+T shares identical 16-pin SSOP pinout and functionality with all MAX4601 variants (e.g., MAX4601CAE, MAX4601EWE), as well as MAX4602EAE+T and MAX4603EAE+T. Pin assignments for IN, COM, NC/NO, V+, V−, VL, and GND are standardized across the family. This allows direct substitution between temperature grades and package types without PCB modification-provided the NC/NO configuration matches the application's functional requirement. MAX4601EAE+T is fully interchangeable at the board level with other E-grade SSOP variants.
