SGM4157

SPDT 1Ω Analog Switch

FEATURES

GENERAL DESCRIPTION

− Voltage Operation : 1. 8 V to 5. 5 V

− On-Resistance: 0.8Ω (TYP) at 4.5V

− -3dB Bandwidth: 80 MHz

− High Off-Isolation: 60dB at 1MHz

− Rail-to-Rail Operation

The SGM4157 is a single Low ON-Resistance(1Ω), fast

single-pole double-throw (SPDT) CMOS switch. It is

designed for low operating voltage, high current switching

of speaker output for cell phone applications. The SGM4157

can handle

balanced microphone/speaker/ringtone

generator in a monophone mode. The device contains a

break−before−make (BBM) feature.

− Low Static Power

− TTL/CMOS Compatible

− Break-Before-Make Switching

− Extended Industrial Temperature Range: –40°C to 85°C

− Microsize Package

The control input, IN, tolerates input drive signals up to

5.5V, independent of supply voltage.

SGM4157 is available in a DFN-6 package.
