Analog Devices Inc./Maxim Integrated MAX383CSE

Overview

The MAX383CSE from Maxim Integrated is a single-pole double-throw (SPDT) precision analog switch with two normally open (NO) and two normally closed (NC) poles, operating from ±3V to ±8V dual supplies or +3V to +15V single supply. It delivers low on-resistance (20Ω typical, 35Ω max), matched channel resistance (<2Ω), flat on-resistance (<4Ω over signal range), <5pC charge injection, and <2.5nA off-leakage at +85°C - enabling high-fidelity signal routing in battery-powered test equipment and military radios.

For engineers reviewing the MAX383CSE datasheet, MAX383CSE pinout, MAX383CSE application, or MAX383CSE equivalent, key selection criteria include rail-to-rail analog signal handling (V− to V+), break-before-make timing (10–20ns), CMOS/TTL logic compatibility across 3V/5V/±3V/±5V supplies, and guaranteed leakage performance at extended temperature.

Technical Context

The MAX383CSE implements a monolithic silicon-gate CMOS architecture optimized for low-voltage precision switching. Its SPDT topology supports independent control of two COM/NO/NC paths via separate IN1 and IN2 logic inputs, with internal protection diodes and rail-to-rail analog voltage handling from V− to V+.

It guarantees break-before-make operation (10–20ns delay) to prevent signal shorting during state transitions, and maintains flat on-resistance (≤4Ω variation) across the full analog input range - critical for minimizing distortion in audio routing and sample-and-hold circuits.

FAQ

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

The MAX383CSE supports analog signals from V− to V+, enabling rail-to-rail operation. With ±5V dual supplies, this spans −5V to +5V; with +5V single supply, it covers 0V to +5V. Absolute maximum ratings allow V+ to +17V and V− 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 conditions in the MAX383CSE datasheet.

Does the MAX383CSE provide break-before-make switching, and is it guaranteed?

Yes, the MAX383CSE provides guaranteed break-before-make operation with a specified delay of 10ns to 20ns, explicitly documented in the Electrical Characteristics table under "Break-Before-Make Time Delay" for MAX383 only. This feature prevents momentary shorting between NC and NO paths during logic transitions, which is critical in RF and precision analog systems. The guarantee applies across the full operating temperature range and is validated per Maxim's production test flow.

What is the on-resistance matching specification for the MAX383CSE, and why does it matter?

The MAX383CSE guarantees on-resistance matching of less than 2Ω between channels, defined as ∆RON = RON(max) − RON(min). This tight matching ensures consistent gain, phase, and settling behavior across multiple switched paths - vital for differential signal routing, instrumentation multiplexing, and calibration accuracy. The specification is tested and guaranteed over the full temperature range and analog signal span, directly supporting high-fidelity applications like sample-and-hold circuits and precision test equipment.

Can the MAX383CSE operate from a single 3.3V supply, and what are the key trade-offs?

Yes, the MAX383CSE operates from a single +3.3V supply (within its +3V to +15V range). At 3.3V, on-resistance rises to 75Ω typical (185Ω max), turn-on time increases to 250ns, and leakage remains below 0.2nA at +25°C. These shifts are fully characterized in the Single +3.3V Supply Electrical Characteristics table. Designers must verify signal integrity and settling time in their specific 3.3V application, especially in high-frequency or low-distortion contexts.

Is the MAX383CSE pin-compatible with industry-standard analog switches like the DG403?

Yes, the MAX383CSE is explicitly stated as pin-compatible with the DG401, DG403, and DG405 in the Features section of its datasheet. This compatibility extends to pin function mapping, package outline (16-pin DIP), and logic polarity - allowing direct replacement in legacy designs without PCB modification. However, designers should verify that the improved specifications (e.g., lower leakage, tighter R_ON match, guaranteed break-before-make) align with system requirements before substitution.
