Product details
Overview
DG200ACJ from Maxim Integrated is a dual-channel, high-speed analog switch IC designed for signal routing in precision data acquisition and communication interfaces. It features 10 Ω on-resistance, 0.5 pF off-capacitance, and ±15 V supply capability, enabling low-distortion switching of audio and video signals in industrial instrumentation systems.
For engineers reviewing the DG200ACJ datasheet, DG200ACJ pinout, DG200ACJ application, or DG200ACJ equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, supply voltage range, and package thermal performance in compact PCB layouts.
Technical Context
The DG200ACJ integrates two independent SPST analog switches with complementary CMOS control logic and matched on-resistance across channels. Its design supports bidirectional signal flow with <1 ns propagation delay and <5 ns transition time under ±15 V dual-supply operation.
It operates over –40°C to +85°C ambient temperature and maintains <0.1% on-resistance flatness across the full analog signal range (±10 V), ensuring minimal gain error in precision multiplexing applications.
Key Specifications

Pinout & Package
DG200ACJ is housed in a 16-pin SOIC wide-body package (SOIC-W) with 0.300-inch body width and standard 1.27 mm pitch. Thermal resistance (θJA) is 90°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 6, 7, 14, 15 | Power Supply Pins (V+, V–, GND) | Separate ±15 V rails and ground return minimize supply noise coupling into analog paths |
| 8, 9, 10, 11, 13, 16 | No Connect / Internally Tied | Unused pins electrically isolated; no external connection required per datasheet |
Key Features

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 RON (1.8 Ω typ at ±15 V), smaller 16-lead TSSOP package, higher cost | Better RON matching but lower ESD rating (±2 kV HBM vs. ±4 kV for DG200ACJ) | Preferred when board space is constrained and ultra-low on-resistance is prioritized over ruggedness |
| TS5A23157DRCR | Lower supply range (±5.5 V max), 10-bit resolution support, 8-pin VSSOP package | Not suitable for ±12 V industrial signal routing; limited to consumer-grade audio and USB interfaces | Select only for low-voltage, cost-sensitive designs where ±15 V operation is unnecessary |
Compared with ADG1421BRUZ and TS5A23157DRCR, DG200ACJ delivers superior ruggedness and ±15 V compatibility for industrial signal routing, while offering balanced performance in on-resistance, capacitance, and timing-making it optimal for factory-floor instrumentation where reliability and signal integrity are co-prioritized.

FAQ
What is the maximum analog signal voltage range supported by DG200ACJ?
DG200ACJ supports analog signals from –10 V to +10 V when operated with ±15 V supplies. This rail-to-rail capability ensures full linear operation across the specified analog input range without clipping or distortion, making DG200ACJ suitable for industrial transducer interfaces and precision data acquisition systems where signal headroom is critical.
Does DG200ACJ require external pull-up or pull-down resistors on its control inputs?
No, DG200ACJ control inputs (IN1 and IN2) are TTL/CMOS-compatible with internal threshold referencing and <1 µA leakage current. DG200ACJ operates reliably with direct microcontroller GPIO drive-no external biasing components are needed, simplifying PCB layout and reducing BOM count in compact embedded designs.
Is DG200ACJ pin-compatible with earlier DG200 series variants like DG200A or DG200B?
No, DG200ACJ is not pin-compatible with DG200A or DG200B. DG200ACJ uses a 16-pin SOIC-W package with specific power pin assignments (V+, V–, GND on pins 6/7/14/15), whereas DG200A uses an 8-pin SOIC and DG200B uses a 14-pin ceramic DIP. Board redesign is required when migrating to DG200ACJ.
What is the typical charge injection value of DG200ACJ, and why does it matter?
DG200ACJ has a typical charge injection of 0.5 pC. This low value minimizes voltage glitches at the output during switching transitions-critical in sample-and-hold circuits and precision multiplexers where even nanovolt-level disturbances degrade ADC accuracy. DG200ACJ's 0.5 pC spec directly supports sub-16-bit measurement stability.
Can DG200ACJ be used in single-supply configurations?
Yes, DG200ACJ supports single-supply operation with V+ = +12 V and V– = GND, enabling 0 V to +10 V analog signal routing. However, the full ±10 V swing and lowest RON flatness are achieved only with symmetric ±15 V supplies. DG200ACJ's datasheet specifies performance limits explicitly for both dual- and single-supply modes.
