Product Overview
The TS5A3166 is a Texas Instruments Signal_Chain device defined as a single-pole single-throw normally open analog switch. Its recommended operating range supports 1.65 to 5.5 V supply operation, 0 to V+ analog input/output voltage, and a 0 to 5.5 V control input range.
At V+ = 4.5 V, the switch has 0.7 Ω typical ON-state resistance at VNO = 2.5 V and 0.8 Ω typical peak ON resistance across 0 ≤ VNO ≤ V+. At V+ = 3 V, the corresponding typical ON resistance is 1 Ω, with 1.1 Ω typical peak ON resistance. Dynamic specifications include 200 MHz bandwidth, -64 dB OFF isolation at 1 MHz, 1 pC typical charge injection, and 0.005% total harmonic distortion over 20 Hz to 20 kHz.
Package options include SOT-23-5, SC70-5, and DSBGA-5 outlines. The device is specified for -40 to 85 °C operation, with package-dependent junction-to-ambient thermal resistance values of 206 °C/W, 252 °C/W, and 132 °C/W.

Procurement Notes
When requesting a quote for TS5A3166, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What switch configuration does the TS5A3166 use?
The TS5A3166 is specified as a single-pole single-throw analog switch. Its condition is normally open, so the NO and COM analog path is open until the digital control input turns the switch on.
What supply voltage range is recommended for TS5A3166?
The recommended operating supply voltage range is 1.65 to 5.5 V. The analog input/output voltage range is 0 to V+, and the control input voltage range is specified from 0 to 5.5 V.
What ON resistance is specified at 4.5 V supply?
At V+ = 4.5 V, the ON-state resistance is 0.7 Ω typical and 0.9 Ω maximum at 25°C, with 1 Ω maximum over the full range. Peak ON resistance is 0.8 Ω typical under the same supply condition.
Which package options are listed for TS5A3166?
The listed package options are SOT-23-5 measuring 2.90 mm x 1.60 mm, SC70-5 measuring 2.00 mm x 1.25 mm, and DSBGA-5 measuring 1.388 mm x 0.888 mm.
