Product details
Overview
DG411CY+T from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It delivers 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection - enabling low-distortion sample-and-hold and audio routing in battery-operated and military-grade equipment.
For engineers reviewing the DG411CY+T datasheet, DG411CY+T pinout, DG411CY+T application, or DG411CY+T equivalent, this page provides verified electrical parameters, package-specific terminal mapping, real-world use scenarios, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The DG411CY+T implements four independent NC SPST switches fabricated in a 44V silicon-gate process, supporting rail-to-rail analog signal handling from ±4.5V to ±20V or +10V to +30V. Its logic interface accepts TTL/CMOS levels via dedicated VL pin, decoupling control voltage from analog supply rails.
Switching is characterized by tON < 150ns and tOFF < 100ns under ±15V operation, with guaranteed RDS(ON) matching ≤3Ω between channels and flatness ΔRDS(ON) ≤4Ω across the full analog range - critical for multi-channel instrumentation where channel-to-channel gain consistency is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at ±15V - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Match | ≤3Ω max difference between any two channels - enables matched gain in multi-path signal conditioning |
| Charge Injection | 10pC max - limits voltage glitch in sample-and-hold circuits and ADC front-ends |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sensor interfaces and long-hold applications |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single - supports industrial, military, and wide-dynamic-range systems |
| Switching Time (tON/tOFF) | <150ns / <100ns - suitable for multiplexed data acquisition up to ~5MHz effective throughput |
| ESD Tolerance | 2000V min per Method 3015.7 - enhances robustness in handling and board-level integration |
Pinout & Package
DG411CY+T is supplied in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm body width, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 9, 12 | S1–S4, GND | Source terminals (S1–S4) and ground reference - S pins are analog return paths; GND is digital logic ground |
| 2, 11, 13 | V−, V+, D2 | Negative supply input (V−), positive supply input (V+), and drain of second switch - V+ connects to substrate; V− sets lower analog rail |
| 5, 6, 7, 8, 10, 14, 15, 16 | D1, IN4, IN3, VL, D3, IN1, IN2, D4 | Drain terminals (D1/D3/D4), logic inputs (IN1–IN4), and logic supply (VL) - INx control corresponding NC switch; VL sets logic threshold (5V for TTL) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor and audio signal routing |
| TTL/CMOS logic compatibility | Separate VL pin allows interfacing with 3.3V or 5V controllers while maintaining ±15V analog performance |
| Low charge injection (10pC) | Minimizes hold-step error in sample-and-hold stages and reduces settling time in switched-capacitor circuits |
| Guaranteed RFLAT(ON) (Δ4Ω) | Ensures consistent on-resistance across ±15V signal swing - critical for linearity in programmable gain amplifiers |
| Improved off-leakage (<5nA @ +85°C) | Enables reliable operation in high-temperature industrial environments without calibration drift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | 44V process, 35Ω RDS(ON), but 25pC charge injection and no guaranteed RFLAT(ON) | Higher glitch energy limits use in precision S/H; less suitable for multi-channel gain-matched systems | Prefer DG411CY+T when charge injection & channel matching are critical; ADG411BRZ acceptable for general-purpose routing |
| TS5A23157DCUR | Lower voltage rating (5.5V max), 0.9Ω RDS(ON), but only ±5.5V analog range and no bipolar support | Not viable for ±15V industrial or military signal chains; limited to low-voltage consumer audio | Select DG411CY+T for wide-supply, high-reliability analog routing; TS5A23157DCUR only for cost-sensitive 3.3V embedded designs |
Compared with ADG411BRZ and TS5A23157DCUR, DG411CY+T uniquely combines bipolar ±20V operation, guaranteed 3Ω channel matching, and 10pC charge injection - making it the only choice for precision, temperature-stable, multi-channel analog switching in demanding environments.

FAQ
What is the maximum analog signal range supported by DG411CY+T?
DG411CY+T supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±20V bipolar or +30V single supply. Under ±15V operation, the guaranteed analog signal range is ±15.5V - enabling full-scale use in industrial instrumentation and military radio front-ends without clipping or distortion.
Is DG411CY+T pin-compatible with the original industry-standard DG411?
Yes, DG411CY+T is a plug-in upgrade for the legacy DG411, sharing identical 16-pin narrow SOIC pinout, logic polarity, and functional behavior. All INx, Dx, Sx, V+, V−, GND, and VL connections map one-to-one - allowing drop-in replacement without PCB modification or firmware changes.
Does DG411CY+T require a separate logic supply voltage?
Yes, DG411CY+T requires a dedicated VL pin for logic interface, which must be tied to 5V for TTL compatibility or to V+ for CMOS-level inputs. This separation ensures noise immunity and allows independent optimization of analog and digital supply domains - a key design feature confirmed in the device's truth tables and timing diagrams.
What is the guaranteed on-resistance flatness specification for DG411CY+T?
DG411CY+T guarantees on-resistance flatness (RFLAT(ON)) of Δ4Ω maximum over the full analog signal range - defined as the difference between max and min RDS(ON) measured at signal extremes. This specification is validated under bipolar ±15V operation and directly enables high-linearity applications such as programmable gain stages and precision attenuators.
Can DG411CY+T operate from unbalanced supplies like +24V and -5V?
Yes, DG411CY+T supports unbalanced supplies - for example, +24V and -5V - as long as the difference between V+ and V− does not exceed +44V and both remain within their absolute maximum ratings. This capability is explicitly documented in the Applications Information section and enables flexible power architecture in mixed-signal systems.
