Analog Devices Inc./Maxim Integrated MAX383CSE+T

Overview

MAX383CSE+T from Maxim Integrated is a precision single-pole double-throw (SPDT) analog switch with two normally open (NO) and two normally closed (NC) poles, designed for rail-to-rail signal routing in low-voltage systems. It delivers 20Ω typical on-resistance (≤35Ω max), <2Ω matched R_ON between channels, <5pC charge injection, and operates from +3V to +15V single supply or ±3V to ±8V dual supplies - enabling use in battery-operated audio routing and military radio front-ends.

For engineers reviewing the MAX383CSE+T datasheet, MAX383CSE+T pinout, MAX383CSE+T application, or MAX383CSE+T equivalent, this page provides verified specifications, package mapping, real-world switching performance data, and validated alternatives for precision analog signal path design under tight leakage and flatness constraints.

Technical Context

The MAX383CSE+T implements a CMOS-based SPDT architecture with break-before-make timing (10–20ns delay) to prevent signal shorting during state transitions. Its silicon-gate process ensures guaranteed on-resistance flatness (<4Ω variation over full analog range) and ultra-low off-channel leakage (<2.5nA at +85°C).

It supports TTL/CMOS logic compatibility across 3V, 5V, ±3V, and ±5V input levels, and maintains rail-to-rail analog signal handling (V_COM, V_NO, V_NC = V₋ to V₊) without level-shifting - critical for sample-and-hold circuits and PBX line interface designs requiring minimal distortion and crosstalk.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Compared with MAX383ESE, MAX383CSE+T trades thermal range for lower cost and tighter initial calibration; versus ADG403BRZ, it delivers significantly lower charge injection and guaranteed R_ON matching - making it the only choice for applications demanding sub-5pC switching integrity.

Availability

MAX383CSE+T is available at Aetrix Electronics and suitable for audio signal routing, military radio front-ends, and sample-and-hold circuits requiring stable component supply across commercial temperature grades.

Supply support for MAX383CSE+T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs high-performance analog and mixed-signal ICs for precision, power, and interface applications - emphasizing low-noise, low-power, and high-reliability operation.

The MAX381/MAX383/MAX385 family was engineered specifically for low-voltage, high-fidelity analog switching in mission-critical systems where leakage, charge injection, and R_ON matching directly impact measurement accuracy and signal integrity.

FAQ

What is the maximum analog signal voltage range supported by the MAX383CSE+T?

The MAX383CSE+T supports rail-to-rail analog signals from V₋ to V₊. With ±5V dual supplies, this means −5V to +5V; with +5V single supply (V₋ = GND), the range is 0V to +5V. Absolute maximum ratings allow V₊ up to +17V and V₋ down to −17V, but functional analog range remains bounded by the applied supply rails. This capability is confirmed in the Electrical Characteristics tables for both dual- and single-supply configurations of the MAX383CSE+T.

Does the MAX383CSE+T require external protection diodes for overvoltage conditions?

No - the MAX383CSE+T includes internal protection diodes on all analog pins (COM, NO, NC), clamping signals to V₊ and V₋. External diodes are only recommended if power-supply sequencing cannot be controlled (e.g., V₊ powered before V₋). When used, they reduce analog range by ~0.7V per rail but preserve MAX383CSE+T's core leakage and resistance specs. This guidance is explicitly stated in the Applications Information section of the MAX383CSE+T datasheet.

Is the MAX383CSE+T pin-compatible with the DG403 analog switch?

Yes - the MAX383CSE+T is explicitly specified as pin-compatible with the DG403 in its Features list and Ordering Information. Both devices share identical 16-pin SO packaging, pin functions (including COM/NO/NC assignments and IN control logic), and supply pin locations (V₊, V₋, GND). This allows direct replacement without PCB modification, provided the system's temperature and leakage requirements align with the MAX383CSE+T's 0°C to +70°C rating.

What is the guaranteed on-resistance matching between channels for the MAX383CSE+T?

The MAX383CSE+T guarantees on-resistance matching of <2Ω between any two channels under specified operating conditions (V₊ = +5V, V₋ = −5V, T_A = T_MIN to T_MAX). This is measured as ∆R_ON = R_ON(max) − R_ON(min) and is distinct from absolute R_ON value. The guarantee applies across the full commercial temperature range and is validated per the Electrical Characteristics table - a key differentiator for differential signal routing where channel imbalance causes common-mode error.

Can the MAX383CSE+T operate from a +3.3V single supply?

Yes - the MAX383CSE+T is fully specified for +3.0V to +3.6V single-supply operation. At +3.3V, typical on-resistance rises to 75Ω (max 185Ω), turn-on time extends to 400ns, and off-leakage remains <0.2nA at +25°C. These values are documented in the "Electrical Characteristics - Single +3.3V Supply" section and confirm reliable function in modern low-voltage embedded systems, including portable test gear and battery-powered comms modules using the MAX383CSE+T.
