Overview
The TS5A3159ADBVRG4 is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 900 mΩ. The device supports bidirectional signal transmission from 0 V to V+ with low distortion characteristics. Key electrical parameters include a maximum charge injection of 36 pC, a bandwidth of 100 MHz, and a maximum power supply current of 500 nA. Switching times are specified as 30 ns for turn-on and 20 ns for turn-off. It is housed in a SOT-23-6 package and functions across an operating temperature range of -40°C to +85°C.
Feature Summary
- Low on-resistance of 900 mΩ ensures minimal signal loss in the conduction path.
- Break-before-make switching action prevents signal shorting between channels during transitions.
- 5.5 V tolerant control inputs allow compatibility with various logic families without level shifting.
- Low charge injection and total harmonic distortion support high-fidelity audio and precision signal routing.
Applications
- Portable audio equipment requiring low-distortion signal paths
- Battery-powered consumer electronics utilizing single-supply operation
- Signal multiplexing in sensing and instrumentation systems
Procurement Notes
Verify the G4 suffix indicates lead-free and RoHS compliance status according to Texas Instruments documentation. Confirm the ADBVR variant corresponds to the SOT-23-6 package and 900 mΩ on-resistance specifications. Cross-reference the manufacturer part number with official datasheets to ensure functional equivalence before integration into designs.
Selection Notes
Select this component when a single SPDT switch with sub-ohm on-resistance is required for low-voltage applications. The 1.65 V minimum supply voltage makes it suitable for battery-operated devices. Ensure the design accommodates the 5.5 V input tolerance if interfacing with higher voltage logic controllers. Verify thermal requirements against the -40°C to +85°C operating range.
Part Context
This part belongs to the TS5A3159 family of analog switches designed for portable and battery-powered applications. The TS5A3159 series offers variations in packaging and specific resistance values, such as the standard 1.1 Ω version found in the TS5A3159DBVR. The ADBVRG4 variant specifically targets cost-sensitive markets while maintaining high performance metrics like low distortion and fast switching speeds.
Replacement Considerations
The TS5A3159DBVR is a related variant with a slightly higher on-resistance of 1.1 Ω but shares similar pinouts and functionality. Other SPDT switches from different manufacturers may require verification of voltage ranges and on-resistance matching to ensure direct replacement capability without circuit modification.
