Product details
Overview
DG202CSE.C30341 from Maxim Integrated is a quad SPST CMOS analog switch with normally open configuration, designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features 175Ω typical on-resistance at ±15V, guaranteed break-before-make switching, and no external VL logic supply requirement. Used in programmable gain amplifiers and automatic test equipment where rail-to-rail analog signal integrity and low power consumption are critical.
For engineers reviewing the DG202CSE.C30341 datasheet, DG202CSE.C30341 pinout, DG202CSE.C30341 application, or DG202CSE.C30341 equivalent, key selection criteria include analog signal range (±15V), leakage performance (±1nA max OFF-leakage), switching speed (480ns turn-on), and SOIC-16 package compatibility with industrial temperature-grade alternatives.
Technical Context
The DG202CSE.C30341 implements monolithic CMOS switch architecture with inverted control inputs relative to DG201/DG211, enabling direct TTL/CMOS logic interface without level-shifting. Its internal structure guarantees nonlatching behavior when supplies are disconnected while analog signals remain present.
All four switches provide symmetrical conduction, constant RDS(ON) across the full analog range, and zero output offset. The device eliminates the third logic supply (VL) required by legacy equivalents while maintaining pin-compatible control timing and signal path specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail signal switching without clipping in ±15V systems |
| Drain-Source ON-Resistance | 175Ω max at ±15V - Ensures minimal insertion loss and gain error in precision signal paths |
| Turn-ON Time | 480ns max - Enables reliable multiplexing in sub-microsecond sampling applications |
| OFF-Leakage Current | ±1nA max at ±14V - Preserves accuracy in high-impedance sample/hold and sensor interfaces |
| Power-Supply Range | ±4.5V to ±18V - Allows operation from standard op-amp rails up to industrial high-voltage supplies |
| Channel ON-Capacitance | 16pF - Limits bandwidth degradation and feedthrough in RF-adjacent analog routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CSE+ | Lower RDS(ON) (60Ω), but only ±5V supply range; requires VL supply | Better for low-voltage portable designs; unsuitable for ±15V industrial signal chains | Select when system uses 3.3V/5V rails and prioritizes on-resistance over voltage range |
| ADG1412BRUZ | Higher supply range (±22V), lower leakage (±0.25nA), but 16-lead TSSOP only | Superior for high-reliability test equipment requiring extended voltage margin and ultra-low leakage | Choose when upgrading legacy DG202CSE.C30341 designs needing improved specs and RoHS compliance |
Compared with DG202CSE.C30341, MAX4617CSE+ trades voltage range for lower on-resistance in battery-powered systems, while ADG1412BRUZ extends voltage and leakage performance at the cost of SOIC-16 footprint compatibility.

FAQ
What is the maximum analog signal voltage supported by DG202CSE.C30341?
DG202CSE.C30341 supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow V+ to V− up to 44V, but the guaranteed linear signal range remains ±15V per the electrical characteristics table. Exceeding ±15V may increase RDS(ON) and leakage beyond specified limits.
Does DG202CSE.C30341 require a separate VL logic supply voltage?
No, DG202CSE.C30341 does not require a VL supply. Unlike earlier DG212 variants, this device integrates logic-level translation internally, accepting standard TTL/CMOS input voltages (0V/5V) directly while operating from ±4.5V to ±18V analog supplies - eliminating the need for a third voltage rail.
What is the thermal performance of DG202CSE.C30341 in SOIC-16 package?
In the 16-pin SOIC package, DG202CSE.C30341 has a power dissipation rating of 696mW at +70°C ambient, with a derating factor of 8.7mW/°C above that temperature. This allows safe continuous operation up to +70°C ambient without forced cooling in typical PCB layouts with standard copper pour.
How does DG202CSE.C30341 handle power-down with live analog inputs?
DG202CSE.C30341 is guaranteed nonlatching when power supplies are disconnected while analog inputs remain active. Internal protection structures prevent parasitic SCR activation, allowing safe hot-swap operation in automatic test equipment and modular instrumentation systems without risk of device damage or system lockup.
Is DG202CSE.C30341 pin-compatible with DG202CSE or DG202CSE+?
Yes, DG202CSE.C30341 shares identical pinout, package (SOIC-16), and electrical behavior with DG202CSE and DG202CSE+. The ".C30341" suffix denotes a specific manufacturing lot or traceability code, not a functional variant - all maintain full drop-in compatibility in existing designs.
