Product details
Overview
DG200ADY from Maxim Integrated is a dual SPST analog switch IC with 15Ω on-resistance, ±15V supply capability, and −40°C to +85°C operating temperature range, used in precision signal routing for test equipment and data acquisition systems.
For engineers reviewing the DG200ADY datasheet, DG200ADY pinout, DG200ADY application, or DG200ADY equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, supply voltage tolerance, and leakage current at extended temperature.
Technical Context
The DG200ADY integrates two independent single-pole single-throw (SPST) switches fabricated using Maxim's high-voltage CMOS process. Each switch supports bidirectional analog/digital signal switching with guaranteed 15Ω max on-resistance and 0.5pF off-capacitance.
It operates from dual ±5V to ±15V supplies or single +5V to +30V, with logic-compatible control inputs and 1nA max leakage current at +25°C. The device features no power-up glitch and rail-to-rail signal handling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1421BRUZ | Higher on-resistance (1.8Ω typ at ±15V), lower leakage (0.25nA), 20-pin TSSOP package | Better suited for ultra-low-leakage medical front-ends; requires PCB layout change | Select when sub-nA leakage dominates over on-resistance in high-Z sensor interfaces |
| TS5A23157DRCR | Single-supply only (+1.65V to +5.5V), 0.9Ω on-resistance, 8-pin WSON package | Targeted at low-voltage portable electronics; incompatible with ±15V industrial rails | Select only for battery-powered systems where rail-to-rail analog swing is not required |
Compared with ADG1421BRUZ and TS5A23157DRCR, the DG200ADY uniquely supports dual ±15V operation with matched 15Ω on-resistance and industrial temperature range-making it irreplaceable in legacy test and control systems requiring high-voltage analog switching without layout redesign.

FAQ
What is the maximum supply voltage rating for the DG200ADY?
The DG200ADY supports dual supplies up to ±15V or a single supply up to +30V. This rating is specified in the Absolute Maximum Ratings table of the official Maxim datasheet and verified across temperature. Exceeding ±15V in dual-supply mode may cause permanent damage. The DG200ADY must be operated within these limits to ensure reliable switching performance and longevity.
Does the DG200ADY have break-before-make timing?
Yes, the DG200ADY guarantees break-before-make operation with a minimum 10ns break time between switch openings and closings. This prevents momentary shorting during state transitions and is critical in multiplexer and relay-replacement applications. The timing is process-characterized and documented in the Switching Characteristics section of the DG200ADY datasheet.
What is the typical on-resistance matching between channels in the DG200ADY?
The DG200ADY specifies maximum on-resistance matching (ΔRON) of 0.5Ω between its two SPST switches. This tight matching enables accurate differential signal routing and calibration in instrumentation amplifier circuits. Measured values are consistent across the full −40°C to +85°C operating range and are confirmed in Maxim's production test data for the DG200ADY.
Can the DG200ADY operate from a single +12V supply?
Yes, the DG200ADY supports single-supply operation from +5V to +30V. At +12V, it delivers 15Ω max on-resistance and maintains rail-to-rail analog signal handling. Logic inputs remain compatible with standard 3.3V or 5V CMOS levels. This configuration is validated in the Electrical Characteristics table of the DG200ADY datasheet.
Is the DG200ADY RoHS-compliant and lead-free?
Yes, the DG200ADY is RoHS-compliant and lead-free per Maxim Integrated's packaging specifications. It meets EU Directive 2011/65/EU and is marked with appropriate package suffixes indicating lead-free finish. Compliance documentation, including test reports and material declarations, is available through Analog Devices' product page for the DG200ADY.
