Product details
Overview
DG202CSE-T from Maxim Integrated is a quad SPST normally open CMOS analog switch designed for precision signal routing in ±4.5V to ±18V dual-supply systems. It features 175Ω typical on-resistance, <1nA off-leakage at ±14V, and guaranteed break-before-make switching. The device operates without a separate logic supply (VL), enabling direct TTL/CMOS compatibility in programmable gain amplifiers and automatic test equipment.
For engineers reviewing the DG202CSE-T datasheet, DG202CSE-T pinout, DG202CSE-T application, or DG202CSE-T equivalent, this page delivers verified specifications, SOIC-16 package details, real-world use scenarios, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The DG202CSE-T implements four independent SPST switches using monolithic CMOS technology with inverted control inputs relative to the DG201 family. Each switch guarantees nonlatching behavior when power supplies are disconnected while analog signals remain present.
Its architecture supports bidirectional current flow, adds no offset voltage to routed signals, and maintains constant RDS(ON) across the full ±15V analog signal range. Switching times are specified at 480ns turn-on and 370ns turn-off under 1kΩ/35pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail signal switching without clipping in ±15V systems |
| RDS(ON) | 115Ω to 200Ω - Low on-resistance ensures minimal signal attenuation and gain error |
| Off-Leakage Current | <±5nA at ±14V - Enables high-impedance sample/hold and precision multiplexer applications |
| Turn-On/Off Time | 480ns / 370ns - Sufficient speed for 1MHz sampling and fast channel switching |
| Supply Range | ±4.5V to ±18V - Wide operating range accommodates industrial and instrumentation power rails |
| Logic Compatibility | TTL/CMOS - Direct interface with microcontrollers and FPGAs without level-shifting |
| Charge Injection | 20pC - Low charge injection minimizes voltage step errors in sample-and-hold circuits |
Pinout & Package
Package: 16-pin SOIC (SO) with 0.150" body width, RoHS-compliant lead finish (non-lead-free), rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs - Low = switch ON (normally open configuration) |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - Analog signal outputs or high-side connection points |
| 3, 6, 11, 14 | S1–S4 | Source terminals - Analog signal inputs or low-side connection points |
| 4 | V− | Negative supply rail - Must be connected to system −VSS; substrate reference |
| 5 | GND | Ground reference - Common return for logic and analog sections |
| 12 | N.C. | No connection - Internally unconnected; must be left floating or tied to GND per layout best practice |
| 13 | V+ | Positive supply rail - Connected to substrate; must be tied to system +VDD |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail - simplifies PCB design and reduces BOM count versus legacy DG212 |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during switching - critical for multiplexer safety |
| Nonlatching with powered-off supplies | Withstands input signals up to ±14V even when V+/V− are off - protects downstream circuitry |
| Constant RDS(ON) over signal range | Minimizes THD and gain nonlinearity in audio and instrumentation signal paths |
| Bidirectional conduction | Enables flexible signal routing - same part used for input or output switching without polarity constraints |
Applications
| Programmable Gain Amplifier | Analog Multiplexer |
|---|---|
Use Scenario: Selecting feedback resistor values in op-amp-based PGA configurations to achieve discrete gain steps. IC Role / Device Role / Timing Role: DG202CSE-T acts as a precision analog switch array routing resistors into the amplifier's feedback loop. Use Value: Low RDS(ON) and negligible offset preserve gain accuracy; break-before-make prevents transient shorts during reconfiguration. |
Use Scenario: Routing multiple sensor inputs to a single ADC channel in data acquisition systems. IC Role / Device Role / Timing Role: DG202CSE-T serves as channel selector with independent SPST control per input path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 4.5Ω RDS(ON), +3V to +36V single-supply operation | Lower on-resistance but limited to unipolar supplies; not pin-compatible | Select for low-RDS(ON) unipolar systems where quad integration is unnecessary |
| ADG1412BRUZ | Quad SPST, 1.8Ω RDS(ON), ±15V supply, 0.2pC charge injection | Superior performance in precision sample/hold; higher cost and different pinout | Choose when sub-pC charge injection and ultra-low on-resistance justify redesign and cost increase |
Compared with DG202CSE-T, MAX4617ESE+ offers lower on-resistance but requires unipolar supply and lacks quad integration, while ADG1412BRUZ delivers significantly better precision metrics at the expense of pinout compatibility and higher unit cost.

FAQ
What is the maximum analog signal voltage supported by the DG202CSE-T?
The DG202CSE-T supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow VS/VD to swing from V− to V+, enabling full rail-to-rail signal handling within the ±15V window. Exceeding ±15V risks violating the specified analog signal range and may degrade linearity or reliability. Always verify actual signal levels against the DG202CSE-T's VANALOG specification in your design.
Does the DG202CSE-T require a separate VL logic supply voltage?
No, the DG202CSE-T does not require a VL supply. Unlike earlier analog switches such as the original DG212, Maxim eliminated the need for a third logic supply while maintaining TTL/CMOS compatibility. The DG202CSE-T accepts logic inputs directly from 0V/5V or 0V/3.3V sources referenced to GND, simplifying power architecture and reducing external component count in the final design.
What is the meaning of "inverted control inputs" in the DG202CSE-T datasheet?
"Inverted control inputs" means that a logic low (≤0.8V) on IN1–IN4 turns the corresponding switch ON, while a logic high (≥2.4V) turns it OFF. This is the opposite behavior of the DG201/DG211 family. For the DG202CSE-T, the default state (no control signal applied) is OFF due to internal pull-down characteristics, making it inherently fail-safe in unpowered or floating logic scenarios.
Can the DG202CSE-T be used in bidirectional signal paths?
Yes, the DG202CSE-T supports fully bidirectional analog signal flow. Its CMOS construction allows current conduction in either direction between S and D terminals, with identical RDS(ON), leakage, and capacitance characteristics regardless of signal polarity or direction. This makes the DG202CSE-T suitable for both input selection and output routing in systems like relay replacements or matrix switchers.
Is the DG202CSE-T RoHS compliant?
The DG202CSE-T is not RoHS/lead-free compliant. Per Maxim's part numbering convention, the "-T" suffix indicates tape-and-reel packaging, while absence of "+" denotes non-lead-free finish. The DG202CSE+T variant is the RoHS-compliant version. Customers requiring lead-free assembly must specify DG202CSE+T or verify alternate lead-free offerings through Aetrix Electronics' compliance documentation.
