Overview
The TPW3157A-CR is a Single Pole/Double Throw (SPDT) analog switch manufactured by 3PEAK. It operates with a supply voltage range of 1.65 V to 5.5 V and features an ultra-low on-state resistance, typically 3 Ω at 4.5 V. The device provides a bandwidth of 100 MHz and fast switching times, with turn-on time of 40 ns and turn-off time of 15 ns. It includes break-before-make switching functionality and latch-up performance exceeding 800 mA. The component supports an operating temperature range from –40°C to 125°C and is housed in a SOT363 (SC70-6) package.
Feature Summary
- Ultra-low on-state resistance for minimal signal loss
