What are the key features of PTMUX1134PWR?
- 4-channel 2:1 SPDT precision analog switch with ultra-low leakage current for high-accuracy signal routing
- Wide supply range: single supply up to 5.5 V or dual supply with negative rail to -2.75 V
- Compact 20-pin TSSOP (R-PDSO-G20) package enabling high-density multiplexing in space-constrained designs
- Introduced 2019 with low on-resistance matching across channels for minimized signal distortion
What is PTMUX1134PWR used for?
The PTMUX1134PWR is ideal for precision data acquisition front ends where low leakage and minimal charge injection are critical, such as instrumentation amplifier input multiplexing and sensor signal routing in industrial measurement systems. Its 4-channel SPDT architecture supports automated test equipment (ATE) signal switching and medical diagnostic instruments requiring accurate sub-millivolt signal paths. The ±2.5 V dual-supply capability allows direct interfacing with bipolar analog signal chains without level shifting.

Frequently Asked Questions
What is the maximum supply voltage supported by the PTMUX1134PWR, and can it handle bipolar supplies?
The PTMUX1134PWR operates from a single positive supply up to 5.5 V and also supports a negative supply rail between -2.25 V and -2.75 V (nominal -2.5 V). This dual-supply capability allows the switch to pass analog signals that swing below ground, which is essential in bipolar instrumentation and audio signal-chain applications with 4 independent SPDT channels.
How many signal channels can the PTMUX1134PWR switch simultaneously, and what is the switch topology?
The device integrates 4 independent single-pole double-throw (SPDT) channels, each capable of connecting one signal source to one of two outputs. With a 2:1 mux topology per channel, the PTMUX1134PWR fits applications requiring parallel multiplexing of 4 analog lines in a single 20-pin TSSOP footprint, reducing external switch ICs and PCB area.
Why is the PTMUX1134PWR preferred over general-purpose CMOS switches in precision measurement designs?
Its low leakage current specification minimizes error currents through high-impedance sensor interfaces, where even nano-ampere leakage can introduce measurable offset voltages in 16-bit or higher resolution systems. Combined with the 5.5 V supply limit and -2.75 V negative rail support, the part handles the full input range of most precision ADC front ends without additional clamping components.
