What are the key features of PTMUX1208PWR?
- 8-to-1 single-ended analog multiplexer architecture enabling routing of up to 8 analog input signals to a single output on a 5 V supply
- General-purpose design with low on-resistance suited for accurate analog signal switching in data acquisition and sensor multiplexing systems
- Small Outline TSSOP package reduces PCB footprint while supporting multiple analog channels in space-constrained industrial and consumer boards
- Introduced in 2018 with modern process technology ensuring compatibility with current 5 V system designs and long-term availability
What is PTMUX1208PWR used for?
PTMUX1208PWR is used in data acquisition systems, test and measurement equipment, and industrial sensor hubs where multiple analog sensor outputs must be routed to a single ADC input channel. Its 8-channel single-ended architecture reduces ADC count and simplifies board design in applications such as temperature monitoring arrays, battery cell voltage scanning, and analog panel instrumentation. The 5 V supply compatibility makes it straightforward to integrate in legacy and mixed-voltage industrial control systems.

Frequently Asked Questions
How many analog input channels can PTMUX1208PWR route, and what supply voltage does it operate from?
PTMUX1208PWR supports 8 analog input channels in an 8-to-1 single-ended multiplexer topology, routing any one of the 8 inputs to a common output under digital control. It operates from a 5 V supply, making it directly compatible with 5 V analog front-ends and ADC reference systems in industrial and consumer data acquisition boards without additional level translation.
For a multi-channel temperature sensor array, why is PTMUX1208PWR a cost-effective alternative to using 8 separate ADC channels?
By multiplexing 8 sensor outputs through a single ADC input, PTMUX1208PWR eliminates the need for 7 additional ADC channels or a more expensive multi-channel ADC. A single 12-bit or 16-bit ADC paired with PTMUX1208PWR can scan all 8 temperature sensors sequentially at 5 V, reducing BOM cost and PCB area in monitoring applications where scan rates of a few hundred hertz per channel are adequate.
What package does PTMUX1208PWR use, and how does that affect board layout for an 8-channel signal path?
PTMUX1208PWR is available in a Small Outline (TSSOP) package, which provides a compact footprint suitable for 8-channel analog routing. Engineers should keep analog signal traces short and separated from digital select lines to minimize crosstalk. The TSSOP form factor allows the device to be placed close to signal sources on a 5 V analog board, shortening high-impedance signal paths.
When would PTMUX1208PWR be chosen over a dual or quad multiplexer for a sensor scanning application?
PTMUX1208PWR's 8-channel capacity is chosen when 5 to 8 sensor inputs need scanning with a single device at 5 V, avoiding the cascading or board-space penalty of using two 4-channel multiplexers. For fewer than 5 inputs a quad device may save area, but when 8 sensors such as thermistors, strain gauges, or analog outputs are present in one zone, a single PTMUX1208PWR minimizes component count and inter-device routing complexity.
