SGM3158
GENERAL DESCRIPTION
The SGM3158 is a dual, bidirectional, single-pole/doublethrow (SPDT) CMOS analog switches designed to operate from a single +1.8V to +5.5V supply. It features high-bandwidth (300MHz) and low ON-resistance (4.5 typ), Targeted applications for audio switching. SGM3158 features guaranteed on-resistance matching (0.3 max) between switches and guaranteed on-resistance flatness over the signal range (2.3 TYP). This ensures excellent linearity and low distortion when switching audio signals. SGM3158 is available in a TDFN-12 package.
4.5 Dual SPDT Analog Switch in 12-pin TDFN
FEATURES
- Voltage Operation : 1. 8 V to 5. 5 V - On-Resistance: 4.5 (typ) at 5.0V - Fast Switching Time tON 20 ns tOFF 15 ns - High Bandwidth: 300 MHz - High Off-Isolation: 51dB at 10MHz - Rail-to-Rail Operation - TTL/CMOS Compatible - Break-Before-Make Switching - Extended Industrial Temperature Range: -40C to 85C - Lead (Pb) Free TDFN-12 Package

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. 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.
