AS1747 Analog Switch IC

Description

The SPDT (single-pole/double-throw) switch AS1747 allows signals below ground to pass through without distortion. This analog switch is ideal for switching audio signals, due to the supply voltage from +1.8V to +5.5V and the low 0.4Ω on-resistance.

This SPDT switch is available in space-saving 10-pin TDFN 3x3 packages and operate over the -40ºC to +85ºC extended temperature range.

Key Features

• Distortion -Free Negative Signal Throughput Down to VCC - 5.5V
• Low On-Resistance (RON) 0.4Ω at +2.7V Supply
• 0.25Ω On-Resistance Flatness
• 0.03Ω On-Resistance Matching
• +1.8V to 5.5V Supply Voltage
• -90dB Crosstalk (100kHz)
• -65dB Off-Isolation (100kHz)
• Available in 10-pin TDFN 3x3 Packages

Applications

The device is ideal for cell phones, PDAs and hand-held devices, notebook computers and MP3 players.
