Overview
The DG9424DQ-T1 is a low voltage, dual supply, low on-resistance quad single-pole-single-throw analog switch manufactured by Vishay Siliconix. It utilizes BiCMOS wafer fabrication technology to operate on single supplies from 3 V to 12 V or dual supplies of ± 3 V to ± 6 V. The device features an on-resistance (RDS(on)) of 1.7 Ω, turn-on time (tON) of 42 ns, and turn-off time (tOFF) of 28 ns. It offers minimal insertion loss (-3 dB at 190 MHz), excellent crosstalk performance, and 2000 V ESD protection. The component is housed in a 16-pin TSSOP package with an operating temperature range of -40 °C to +85 °C.
Feature Summary
- BiCMOS wafer fabrication technology enables operation across wide dynamic ranges with low signal errors and distortion.
- Break-before-make switching action prevents simultaneous connection during state transitions.
- TTL and CMOS compatible logic simplifies digital control interfacing.
- Low leakage current characteristics ensure high isolation when switches are in the off state.
Applications
- Automatic test equipment
- Data acquisition systems
- Communication systems
- ADC systems
- Audio signal routing
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance status and packaging details. Ensure that the selected variant matches the required thermal and electrical specifications for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component based on its low on-resistance and fast switching speeds suitable for audio and video signal routing. Consider the single or dual supply requirements and verify that the analog signal range aligns with the system's voltage levels. Evaluate the package constraints and thermal dissipation capabilities within the target design.
Part Context
The DG9424DQ-T1 belongs to the DG9424, DG9425, and DG9426 family of low voltage precision monolithic quad SPST analog switches. These devices share similar core technologies but differ in control logic and switch configuration. The DG9424 specifically responds to standard logic inputs, distinguishing it from the inverse logic of the DG9425 and the mixed configuration of the DG9426.
