Frequently Asked Questions
What bandwidth does the PTMUX1308PWR support for analog signal routing?
The PTMUX1308PWR supports a nominal bandwidth of 500 MHz, making it suitable for high-speed analog and RF signal switching applications. Combined with its 4 Ω on-state resistance and 100 dB off-state isolation, it delivers low insertion loss and excellent channel separation across wideband frequency ranges.
How many input channels can the PTMUX1308PWR switch, and what logic voltage controls it?
The PTMUX1308PWR is an 8:1 multiplexer that selects one of 8 analog input channels to a single output. It is controlled by a 1.8-V logic interface, making it directly compatible with modern low-voltage FPGAs, DSPs, and microcontrollers without requiring additional level shifting circuitry.
In which package does the PTMUX1308PWR come, and how does it fit compact PCB designs?
The PTMUX1308PWR is housed in a 16-pin SOIC (R-PDSO-G16) package, which offers a compact footprint suitable for space-constrained PCB designs. Its small outline form factor simplifies board routing while supporting up to 8 analog channels with 500 MHz bandwidth and 4 Ω on-state resistance.
What isolation performance can designers expect between unselected channels of the PTMUX1308PWR?
Unselected channels of the PTMUX1308PWR provide a nominal off-state isolation of 100 dB, which is critical in multi-channel test equipment and RF switching matrices. This high isolation level minimizes crosstalk between adjacent signals, ensuring measurement accuracy and signal integrity across its 8-channel configuration.
