Analog Devices Inc./Maxim Integrated DG202CSE+

Overview

DG202CSE+ 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 on-resistance at ±15V, <5nA off-leakage, and CMOS/TTL-compatible control inputs - enabling use in programmable gain amplifiers and automatic test equipment.

For engineers reviewing the DG202CSE+ datasheet, DG202CSE+ pinout, DG202CSE+ application, or DG202CSE+ equivalent, this page delivers verified electrical parameters, SO-16 package mapping, real-world timing behavior (480ns turn-on), leakage limits across temperature, and validated alternatives for analog multiplexer design.

Technical Context

The DG202CSE+ implements four independent CMOS transmission gates with inverted logic control inputs - distinguishing it from the DG201/DG211 family. Each switch supports rail-to-rail analog signal handling from –15V to +15V while maintaining constant R_DS(ON) over the full voltage range.

Its monolithic low-power architecture eliminates the need for a separate VL logic supply, unlike legacy equivalents. Internal protection diodes clamp input signals exceeding V+ or V–, limiting current to 25mA without latch-up even when supplies are disconnected during signal presence.

FAQ

What is the maximum analog signal voltage range supported by the DG202CSE+?

The DG202CSE+ supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow continuous operation from ±4.5V to ±18V, and the analog signal can swing rail-to-rail within the supply rails - e.g., from –15V to +15V with V+ = +15V and V– = –15V. This makes DG202CSE+ suitable for industrial instrumentation and test equipment interfacing with bipolar signals.

Does the DG202CSE+ require a separate logic supply voltage (VL)?

No, the DG202CSE+ does not require a VL supply. Unlike earlier analog switches such as the original DG212, Maxim's DG202CSE+ integrates logic-level translation internally, accepting standard CMOS/TTL input voltages referenced to GND while operating from dual ±V supplies. This eliminates the need for a third power rail and simplifies system design - a confirmed feature documented in the device's General Description and Pin Description sections.

What is the typical on-resistance (R_DS(ON)) of the DG202CSE+ and how does it vary with supply voltage?

The DG202CSE+ has a typical R_DS(ON) of 175Ω at ±15V supplies and 1mA load current. As shown in the "Typical R_DS(ON) vs. Power Supplies" graph, R_DS(ON) increases to ~250Ω at ±10V and ~350Ω at ±5V. This voltage-dependent behavior is inherent to CMOS switch architecture and must be accounted for in low-distortion or high-precision gain-setting applications using DG202CSE+.

How does the DG202CSE+ prevent latch-up when power supplies are disconnected?

The DG202CSE+ incorporates process-level design features that guarantee non-latching behavior even when V+ and V– are removed while analog signals remain present at S or D pins. Internal clamping diodes limit input current to 25mA, and the CMOS structure avoids parasitic SCR activation. This fault tolerance is explicitly guaranteed in the datasheet's General Description and Absolute Maximum Ratings sections - a key differentiator for hot-swap and modular system designs using DG202CSE+.

What is the switching speed performance of the DG202CSE+ and what load conditions define it?

The DG202CSE+ has a typical turn-on time (t_ON) of 480ns and turn-off time (t_OFF1) of 370ns, measured under standardized conditions: V+ = +15V, V– = –15V, RL = 1kΩ, CL = 35pF, and VS = +2V. These values reflect real-world dynamic performance in buffered analog routing applications and are specified across the full 0°C to +70°C commercial temperature range for the DG202CSE+ variant.
