What are the key features of TMUX1101DCKT?

  • Single-pole double-throw (SPDT) 1-channel analog switch with ultra-low on-resistance under 1 Ohm minimizes signal attenuation in precision analog paths
  • Wide supply range of 1.62 V to 5.5 V enables use across 1.8 V, 3.3 V, and 5 V system power rails without level shifting
  • SOT-23-5 package with only 5 pins occupies minimal PCB area, ideal for dense portable and wearable device layouts

What is TMUX1101DCKT used for?

TMUX1101DCKT is used in portable medical devices, handheld test instruments, and IoT sensor nodes where a compact, low-power analog signal router is needed between sensor outputs and ADC inputs. Its sub-1-Ohm on-resistance preserves signal integrity for precision measurements up to audio frequencies. The wide supply voltage range allows seamless integration with both 1.8 V and 3.3 V system rails common in battery-powered designs.

Frequently Asked Questions

What on-resistance does TMUX1101DCKT achieve, and why does it matter for ADC input accuracy?

TMUX1101DCKT achieves a typical on-resistance below 1 Ohm across its 1.62 V to 5.5 V supply range. When paired with an ADC input impedance of 10 kOhm or higher, this low resistance contributes less than 0.01% gain error, preserving 12-bit or 16-bit measurement accuracy in precision data acquisition systems.

Can TMUX1101DCKT replace a TS5A3159 analog switch in a 3.3 V design with a SOT-23-5 footprint?

TMUX1101DCKT is a drop-in pin-compatible alternative to the TS5A3159 in 3.3 V SPDT switching applications sharing the SOT-23-5 5-pin footprint. Both devices support signal voltages from 0 V to the supply rail with comparable bandwidth exceeding 1 GHz, making TMUX1101DCKT a lower-cost or more available substitute in production.

How does TMUX1101DCKT perform at high signal frequencies in RF or high-speed data path switching?

The device supports signal bandwidth exceeding 1 GHz with insertion loss typically below 0.5 dB at 100 MHz, suitable for video and broadband analog signal routing. For RF switching above 500 MHz, designers should verify isolation and crosstalk specifications in the application context, as the SOT-23-5 parasitic inductance becomes relevant at those frequencies.
