SGM4581/2/3 Low Power, High Performance, HV Analog Switches

Analog switch is an important component in multi-channel data acquisition systems and its performance will have an impact on subsequent signal processing steps. General purpose parts available on the market suchas CD4051/2/3, 74HC4051/2/3 are among engineers choices due to their low cost. However, many data acquisition systems have more demanding requirements on Ron, bandwidth, isolation and leakage which cannot be accommodated by general purpose switches. SGMICRO’s high performance, low power and high voltage SGM4581/2/3 series will meet application specs on performance as well as the cost budget, thus is popular among design engineers.

The SGM4581/2/3 HV analog switch series is a pin compatible part, no need to change the PCB design. Please refer to the comparison table below for details.
