| SGM4684 GENERAL DESCRIPTION Chip Scale Packaging, Low-Voltage 0.4, Dual, SPDT Analog Switch FEATURES - - - - - Low Voltage Operation : 1. 8 V to 5. 5 V Low On-Resistance: 0. 4(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 W) TTL/CMOS Compatible Chip Scale Packaging 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 (0.4) 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) - - - - PIN CONFIGURATIONS/BLOCK DIAGRAM (top view) CSP C NC1 B GND A NC2 1 IN1 IN2 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 LOGIC 0 1 COM1 COM2 2 3 NO1 V+ NO2 4 FUNCTION TABLE NC1, NC2 ON OFF NO1, NO2 OFF ON Shengbang Microelectronics Co, Ltd Tel: 86/451/84348461 www.sg-micro.com REV.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. (1) Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
