SGM4684 Chip Scale Packaging, Low-Voltage 0.4Ω, Dual, SPDT Analog Switch GENERAL DESCRIPTION The SGM4684 is a dual, low ON-resistance, low voltage, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single +1.8V to +5.5V supply. Targeted applications include battery powered equipment that benefit from low RON (0.4Ω) and fast switching speeds (tON = 25 ns, tOFF = 28 ns). The on resistance profile is very flat over the full analog signal range. This ensures excellent linearity and low distortion when switching audio signals. The SGM4684 is a committed dual single-pole/double -throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer. SGM4684 is available in a 10-ball Chip Scale Packaging (CSP) FEATURES − − − − − − − − − Low Voltage Operation : 1. 8 V to 5. 5 V Low On-Resistance: 0. 4Ω(TYP) Low On-Resistance Flatness –3 dB Bandwidth: 30 MHz Fast Switching Time tON 25 ns tOFF 28 ns Rail-to-Rail Operation Typical Power Consumption (<0.01 µW) TTL/CMOS Compatible Chip Scale Packaging PIN CONFIGURATIONS/BLOCK DIAGRAM (top view) CSP C B A NC1 GND NC2 1 IN1 IN2 2 COM1 COM2 3 NO2 4 APPLICATIONS Battery powered, Handheld, and Portable Equipments Cellular/mobile Phones Laptops, Notebooks, Palmtops Communication Systems Sample-and-Hold Circuits Audio Signal Routing Audio and Video Switching Portable Test and Measurement Medical Equipment Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com NO1 V+ FUNCTION TABLE LOGIC NC1, NC2 NO1, NO2 0 1 ON OFF OFF ON REV.
