4.5Ω Low Voltage SPDT

SGM3157

Analog Switch in 6-pin SC70

FEATURES

GENERAL DESCRIPTION

The SGM3157 is a single, 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

SGM3157 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.

SGM3157 is available in a SC70-6 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.
