1 / 11 page  June. 2009. Revision 1.3 MagnaChip Semiconductor Ltd. 1 Ordering Information Typical Application Part Number Top Marking Ambient Temperature Range Package [mm] RoHS Status MSI2021QH S2U -40℃ to +85℃ 1.4mm x 1.8mm x 0.5mm, 10 leads QFN Halogen-Free 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 detailed information, please contact your local MagnaChip sales office in world-wide or visit MagnaChip’s website at www.magnachip.com. Features ± 8kV Human Body Model (HBM) ESD protection on all pins Low RON : 0.4Ω (typical) @ 3.0V VDD -3dB bandwidth : >50MHz (typical) Low supply current in standby mode (<1 μA) and under wide control voltage range High channel crosstalk: -70dB @ 3.0V VDD Power-Off protection (VDD=0V) and power-On protection (VDD≠0V) on COMA & COMB tolerate up to 4.3V VDD+0.5V signals can be handled under VDD supply voltage condition Halogen-Free 10 leads 1.4mm x 1.8mm QFN package Applications Analog Signal Switching Block Negative Stereo Audio Switching Switching application in portable devices (Cell phone, PDAs, Notebook Computers) + VDD = V_BATT - + - + - MSI2021 RECEIVER A0 A1 B0 B1 COMA COMB 1 st Audio AMP 2 nd Audio AMP |
