TS5A3159ADBVR

Overview

The TS5A3159ADBVR is a single-channel SPDT analog switch manufactured by Texas Instruments, designed for low-distortion signal routing in portable applications. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features a maximum on-resistance of 900 mOhms. The device supports bidirectional I/O signals from 0 V to V+ with a maximum DC switch current of 100 mA. Key electrical parameters include a maximum power supply current of 500 nA, a bandwidth of 100 MHz, and a crosstalk specification of -64 dB at 1 MHz. Switching times are defined by a maximum turn-on time of 30 ns and a maximum turn-off time of 20 ns. The component functions within an operating temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Offers break-before-make switching action to prevent signal distortion during channel transitions
• Provides high isolation in the off state when the supply voltage is zero
• Features 5.5 V tolerant control inputs for compatibility with various logic levels

Applications

• Portable audio equipment requiring low total harmonic distortion
• Communication and networking signal routing
• Sensing and instrumentation systems
• Imaging, video, and visual display interfaces

Procurement Notes

Verify the specific suffix 'ADBVR' against the manufacturer's official datasheet to confirm the exact on-resistance grade and packaging configuration. Ensure the ordering documentation matches the SOT-23-6 package type and the specified electrical characteristics for the A-grade variant. Cross-reference the part number with the latest Texas Instruments product selection guide to validate availability and compliance status before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require precise analog signal switching with minimal insertion loss and distortion. The low on-resistance and high bandwidth make it suitable for maintaining signal integrity in audio and data lines. Consider the SOT-23-6 footprint constraints and the 1.65 V to 5.5 V supply range when integrating into battery-powered or low-voltage systems. Verify thermal performance requirements against the specified operating temperature range for the target application environment.

Part Context

This device belongs to the TS5A3159 family of analog switches, which includes variants such as the TS5A3159DCKR and TS5A3159ADCKR. These parts share similar functional architectures but differ in package types like SC-70-6 and specific electrical tolerances. The family is engineered for general-purpose multiplexing and demultiplexing tasks where small form factor and low power consumption are critical design drivers.

Replacement Considerations

The TS5A3159DCKR serves as a pin-compatible alternative in the SC-70-6 package, though it exhibits a higher maximum on-resistance of 1.1 Ohms compared to the 900 mOhms of the ADBVR variant. Designers must evaluate if the increased resistance impacts signal integrity in their specific circuit topology before substituting.
