Overview
The DG448DV-T1-E3 is a low power, high voltage single-pole/single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates from a single 7 V to 36 V supply or dual ± 4.5 V to ± 20 V supplies. The device features a maximum on-resistance of 25 Ω and an on-resistance flatness of 2.2 Ω over the specified analog signal range. It provides fast switching with a turn-on time of 100 ns and turn-off time of 50 ns. The component supports rail-to-rail signal handling within a ± 15 V analog signal range and utilizes TTL/CMOS compatible logic inputs without requiring a separate logic supply.
Feature Summary
- Supports wide dynamic range with rail-to-rail signal handling capabilities
- Features break-before-make switching action for reliable operation
- Operates directly from single or dual power supplies without external logic voltage requirements
Applications
- Precision test equipment
- Communications systems
- Audio equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature range compliance. Ensure that the selected variant matches the required lead configuration and material categorization standards for the intended deployment environment.
Selection Notes
Select this component when designing circuits requiring high voltage tolerance and low power consumption in a compact footprint. Evaluate the 25 Ω on-resistance limit against the load current requirements to ensure acceptable voltage drop and power dissipation levels under worst-case operating conditions.
Part Context
This part belongs to the DG447/DG448 family of low power, high voltage SPST analog switches. Unlike the DG447 which includes a normally closed switch, the DG448 is configured as a normally open switch. Both devices share identical electrical characteristics and are housed in the standard 6-pin TSOP package.
