Overview
The TS12A12511DGKR is a single SPDT analog switch manufactured by Texas Instruments. It operates with a supply voltage range of ±6 V or +12 V and features a low on-resistance (rON) of 5 Ω. The device utilizes a 5-pin SOT-23 package for compact surface-mount installation. It supports bidirectional signal transmission and includes overvoltage protection capabilities. The component is designed for applications requiring low power consumption and high signal integrity in portable and battery-operated systems.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing
- Low on-resistance of 5 Ω for minimal signal loss
- Wide supply voltage compatibility including dual ±6 V and single +12 V
- Bidirectional signal flow support
Applications
- Portable consumer electronics
- Battery-powered measurement instruments
- Audio and video signal switching
- Data acquisition systems
Procurement Notes
Verify the specific suffix DGKR corresponds to the 5-pin SOT-23 tape-and-reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure static-sensitive handling procedures are followed during storage and assembly to prevent electrostatic discharge damage to the semiconductor junctions.
Selection Notes
Select this component when a single-channel SPDT switch is required with low on-resistance under ±6 V or +12 V supplies. Compare against alternative series such as TS5A series if lower resistance at 5 V is needed. Verify that the 5-pin SOT-23 footprint aligns with the target PCB layout constraints and thermal requirements.
Part Context
This part belongs to the TS12A family of low-voltage analog switches from Texas Instruments. It serves as a discrete solution for signal path management in space-constrained designs. The DGKR suffix indicates the specific reel quantity and pin configuration distinct from other variants like DCNR.
Replacement Considerations
Direct substitutes include TS12A12511DCNR, which shares identical electrical characteristics but differs in packaging form factor. Alternative SPDT switches from other manufacturers may require verification of on-resistance and supply voltage limits.
