MSI2021
0.4Ω Dual SPDT Analog Switch with Negative Swing Feature
General Description
The MSI2021 is a dual single-pole double-throw (dual
SPDT) analog device aimed for analog signals
switching applications in various portable electrical
devices. It is especially designed for negative stereo
audio signals switching applications in mobile phones.
The MSI2021 features very low on-channel resistance
allowing little attenuation and distortion during bi-
directional audio signal routing. High crosstalk and off-
isolation result in minimum noise interference with
good signal integrity. Also the device features very low
current consumption during standby and idle mode
making longer battery operation in portable devices.
The MSI2021 is available in ultra small Halogen-Free
10 leads 1.4 x 1.8 QFN package and can operate over
-40°C to +85°C ambient temperature range. For more
