Overview
The DG411CUE+ is a quad, single-pole/single-throw (SPST) analog switch in a 16-pin TSSOP package. It operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device features a maximum on-resistance of 45Ω, with an on-resistance match between channels of 3Ω max and flatness of 4Ω max. Turn-on time is 175ns maximum, while turn-off time is 145ns maximum. Charge injection is limited to 10pC max. The operating temperature range for the C suffix is 0°C to +70°C.
Feature Summary
- Provides low on-resistance matching between switches and guaranteed on-resistance flatness over the signal range.
- Features improved charge injection and lower off-leakage current over temperature compared to previous generations.
- Supports rail-to-rail signal handling with TTL/CMOS logic compatibility.
Applications
- Sample-and-Hold Circuits
- Communication Systems
- Test Equipment
- Battery-Operated Systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through the supplier's declaration. Ensure the component source is authorized to guarantee authenticity and traceability.
Selection Notes
Select this part for applications requiring low power consumption and fast switching speeds within a standard industrial temperature range. Verify that the required analog signal voltage falls within the specified single or dual supply limits. Check pinout compatibility if replacing legacy devices in existing designs.
Part Context
This component belongs to the DG411/DG412/DG413 series of improved monolithic CMOS analog switches. The DG411 variant specifically utilizes normally closed switches. These devices are designed as drop-in replacements for older industry-standard models, offering enhanced performance metrics such as reduced charge injection and better resistance matching.
Replacement Considerations
The DG411CUE+ serves as a direct replacement for the legacy DG411CUE. Verify that any substitute maintains the same 16-pin TSSOP footprint and electrical characteristics to ensure circuit compatibility without redesign.
FAQ
What is the logic sense of the DG411?
The DG411 consists of four normally closed (NC) SPST analog switches. A logic '0' input turns the switch ON, and a logic '1' input turns it OFF.
How does the DG411 handle electrostatic discharge?
The device guarantees a minimum ESD tolerance of 2000V per Method 3015.7, providing robust protection against static discharge events.
Can the DG411 operate with unbalanced power supplies?
Yes, the device can operate with unbalanced supplies, such as +24V and -5V, provided the difference between V+ and V- does not exceed the absolute maximum ratings.
