Analog Devices Inc./Maxim Integrated MAX4664ESE+T

Overview

MAX4664ESE+T from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, 5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling-designed for reed relay replacement in automatic test equipment and low-distortion audio routing.

For engineers reviewing the MAX4664ESE+T datasheet, MAX4664ESE+T pinout, MAX4664ESE+T application, or MAX4664ESE+T equivalent, key selection criteria include guaranteed R_ON matching (≤0.5Ω), off-leakage ≤5nA at +85°C, break-before-make timing (not applicable-MAX4664 only), and SOIC-16 narrow-body package compatibility.

Technical Context

The MAX4664ESE+T implements CMOS-based transmission-gate architecture with integrated level-shifting logic inputs compatible with TTL/CMOS thresholds across its full supply range. Its analog path supports bidirectional rail-to-rail signals up to ±10V with flat on-resistance (≤0.5Ω variation) over the entire signal range.

All four switches operate independently with logic-controlled NC configuration: INx = low → COMx connected to NCx; INx = high → all NC paths open. The device features internal ESD protection (>2kV per Method 3015.7) and operates across –40°C to +85°C without derating.

FAQ

What is the operating temperature range for the MAX4664ESE+T?

The MAX4664ESE+T is rated for –40°C to +85°C ambient operation, validated across the full range for all electrical parameters including on-resistance, leakage, and switching times. This extended industrial temperature grade ensures reliability in harsh environments such as avionics bays and outdoor telecom cabinets - unlike the commercial-grade C-suffix variants limited to 0°C to +70°C.

Does the MAX4664ESE+T support dual-supply operation?

Yes, the MAX4664ESE+T fully supports dual-supply operation from ±4.5V to ±20V, enabling true bipolar signal handling. When used in dual-supply mode, the V+ and V− pins define symmetric analog rails, while VL remains at +5V for logic interface. This configuration is essential for applications like audio line drivers and sensor front-ends requiring negative signal excursions.

Is the MAX4664ESE+T pin-compatible with other members of the MAX466x family?

Yes, the MAX4664ESE+T shares identical pinout and package (16-pin narrow SOIC) with MAX4665ESE+T and MAX4666ESE+T. However, internal switch configuration differs: MAX4664 is NC-only, MAX4665 is NO-only, and MAX4666 combines two NC + two NO with break-before-make timing. Swapping requires logic-level verification but no PCB change.

What is the maximum signal voltage the MAX4664ESE+T can handle?

The MAX4664ESE+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of –44V to +44V on V+ and V− relative to GND. In practice, the usable signal range is bounded by the applied supply rails - e.g., with ±15V supplies, signals from –15V to +15V pass unattenuated, provided they remain within the specified ±10V common-mode window for guaranteed R_ON flatness.

How does the MAX4664ESE+T achieve low distortion in audio applications?

The MAX4664ESE+T achieves low distortion through three design features: 5Ω max on-resistance with ≤0.5Ω matching across channels, ≤0.5Ω R_ON flatness over ±10V signal swing, and rail-to-rail capability that avoids clipping. These ensure uniform gain and phase response across frequency and amplitude - critical for maintaining THD <0.01% in professional audio routing paths.
