Analog Devices Inc./Maxim Integrated DG212CSE+

Overview

DG212CSE+ from Maxim Integrated is a quad SPST normally open analog switch IC designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 175Ω typical R_DS(ON) at ±15V, <5pF OFF-capacitance per channel, and CMOS/TTL logic compatibility - enabling use in programmable gain amplifiers and automatic test equipment.

For engineers reviewing the DG212CSE+ datasheet, DG212CSE+ pinout, DG212CSE+ application, or DG212CSE+ equivalent, key selection criteria include analog signal range (±15V), leakage performance (±5nA max ID(OFF)), switching speed (460ns t_ON), and absence of VL supply requirement - critical for portable and space-constrained designs.

Technical Context

The DG212CSE+ implements four independent SPST switches using monolithic CMOS process technology with inverted control inputs relative to DG201/DG211. Each switch guarantees nonlatching behavior when power supplies are disconnected while analog signals remain applied.

It operates without a separate logic supply (VL), accepting standard CMOS/TTL input levels directly referenced to GND, and maintains constant on-resistance across its full ±15V analog signal range - supporting precision signal routing in both directions with no added offset.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by DG212CSE+?

DG212CSE+ supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow up to ±18V continuous operation, but the guaranteed linear signal range remains ±15V per the Electrical Characteristics table. This makes DG212CSE+ suitable for industrial and telecom applications requiring full rail-to-rail analog handling without clipping or distortion.

Does DG212CSE+ require a separate logic supply voltage (VL)?

No, DG212CSE+ does not require a VL supply. Unlike earlier DG212 variants, Maxim's implementation eliminates the need for a third logic supply by integrating level-shifting circuitry that accepts standard CMOS/TTL input voltages (0V and ≥2.4V) referenced directly to GND. This simplifies power design and reduces board space - a key differentiator confirmed in the Features section and Typical Operating Circuit diagram.

What is the on-resistance (R_DS(ON)) specification for DG212CSE+ and how does it vary?

DG212CSE+ specifies R_DS(ON) as 115Ω (min) to 175Ω (typ) at ±15V supplies with ±10V analog signal and 1mA test current. The datasheet confirms this value remains essentially constant across the full ±15V analog signal range - a critical feature for precision gain-setting and low-distortion signal routing. At lower supplies (e.g., ±10V), R_DS(ON) increases to ~250Ω, as shown in the R_DS(ON) vs. Power Supplies graph.

How does DG212CSE+ ensure safe operation when power supplies are disconnected?

DG212CSE+ is guaranteed nonlatching when V+ and V− are turned off while analog signals remain present at S/D pins - a feature explicitly verified in the Absolute Maximum Ratings and General Description sections. Internal protection structures prevent parasitic SCR activation, allowing DG212CSE+ to safely tolerate hot-swap conditions and fault scenarios common in automated test and modular instrumentation systems.

What package type and pin count does DG212CSE+ use?

DG212CSE+ uses a 16-pin SOIC (Small Outline Integrated Circuit) package conforming to JEDEC MS-012 outline, with 1.27mm lead pitch and standard body dimensions (10.00mm × 4.00mm). This surface-mount package is RoHS-compliant and optimized for reflow assembly. Pin 1 is marked with a notch or dot; pins 12 and 13 are NC and V+, respectively - as confirmed in the Pin Configurations and Pin Description sections.
