Analog Devices Inc./Maxim Integrated DG201ACSE+

Overview

DG201ACSE+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for precision signal routing in ±4.5V to ±18V dual-supply systems. It features 115Ω typical R_DS(ON), 450ns max turn-off time, 600ns max turn-on time, and guaranteed break-before-make switching. It operates across 0°C to +70°C and is used in test equipment signal path selection.

For engineers reviewing the DG201ACSE+ datasheet, DG201ACSE+ pinout, DG201ACSE+ application, or DG201ACSE+ equivalent, key selection criteria include analog signal range (±15V), low leakage (±0.02nA off-leakage), CMOS/TTL logic compatibility, and SO-16 package compatibility with industrial-grade thermal derating (8.7mW/°C above +70°C).

Technical Context

The DG201ACSE+ implements monolithic CMOS architecture with four independent SPST switches, each controlled by dedicated logic inputs (IN1–IN4). Its internal design eliminates the need for a third VL supply-unlike legacy DG211-simplifying power architecture in portable and embedded systems.

It guarantees nonlatching behavior when power supplies are disconnected while analog signals remain present, and supports full analog signal swing from V− to V+, enabling bidirectional signal handling in ±15V systems without level-shifting circuitry.

FAQ

What is the maximum analog signal voltage range supported by the DG201ACSE+?

The DG201ACSE+ supports an analog signal range of ±15V, meaning it can pass signals from V− to V+ without distortion or clipping when operated with ±15V supplies. This range is specified under standard test conditions (V+ = +15V, V− = −15V, T_A = +25°C) and remains functional across its full operating temperature range (0°C to +70°C). The DG201ACSE+ maintains this capability due to its monolithic CMOS process and internal protection diodes that clamp overvoltage transients.

Does the DG201ACSE+ require a third VL supply voltage like some legacy analog switches?

No, the DG201ACSE+ does not require a third VL supply. Unlike the original manufacturer's DG211, Maxim's DG201ACSE+ integrates logic-level translation internally, eliminating the need for an external VL rail. This simplifies power design, reduces component count, and improves reliability in portable and space-constrained applications. All logic inputs (IN1–IN4) are directly compatible with standard CMOS and TTL voltage levels referenced to GND.

What is the guaranteed switching timing performance of the DG201ACSE+?

The DG201ACSE+ guarantees a maximum turn-off time of 450ns and a maximum turn-on time of 600ns under standard test conditions (V+ = +15V, V− = −15V, R_L = 1kΩ, C_L = 35pF). These values are production-tested limits-not typical values-and ensure predictable timing margins in high-speed multiplexing applications such as automated test equipment and real-time signal routing. Break-before-make timing is also guaranteed to prevent signal shorting during transitions.

How does the DG201ACSE+ handle power-down scenarios with live analog inputs?

The DG201ACSE+ is guaranteed nonlatching when power supplies are disconnected while analog signals remain present-a critical feature for hot-swap and fault-tolerant systems. Internal design prevents parasitic SCR formation, allowing safe operation even when V+ and V− are removed while ±15V signals persist on S/D pins. This behavior is validated across the full temperature range and eliminates the need for external protection circuitry in many industrial and military applications.

What package type and thermal characteristics apply to the DG201ACSE+?

The DG201ACSE+ is supplied in a 16-pin SOIC (SO-16) package per JEDEC MS-012, with 3.90mm body width and 1.27mm lead pitch. Its power dissipation is rated at 696mW at +70°C, with thermal derating of 8.7mW/°C above that temperature. This package supports standard reflow profiles and provides adequate thermal performance for continuous operation in industrial enclosures without forced airflow, provided board layout includes sufficient copper pour on V+ and V− pads.
