4.5Ω Dual SPDT

SGM3158

Analog Switch in 12-pin TDFN

FEATURES

GENERAL DESCRIPTION

The SGM3158 is a dual, bidirectional, single-pole/double-

throw (SPDT) CMOS analog switches designed to operate

−

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

On-Resistance: 4.5Ω (typ) at 5.0V

Fast Switching Time

from

single +1.8V to +5.5V supply. It features

t^ON20 ns

t^OFF15 ns

high-bandwidth (300MHz) and low ON-resistance (4.5Ω

typ), Targeted applications for audio switching.

−

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:

–40°C to 85°C

SGM3158 features guaranteed on-resistance matching (0.3Ω

max) between switches and guaranteed on-resistance

flatness over the signal range (2.3Ω TYP). This ensures

excellent linearity and low distortion when switching audio

signals.

SGM3158 is available in a TDFN-12 package.
