MAX4908 - Dual 3:1 Clickless Audio Multiplexers

General Description

The MAX4908/MAX4909/MAX4930/MAX4932 dual 3:1 clickless audio multiplexers feature negative-signal capability that allows signals as low as VCC - 5.5V to pass through without distortion.

Key Features

  • Distortion-Free Negative Signal Throughput Down to VCC - 5.5V.
  • Internal Shunt Resistors Reduce Click-and-Pop Sounds.
  • High PSRR Reduces Supply Noise.
  • Low On-Resistance: 0.38Ω (typ).
  • Channel-to-Channel Matching: 0.1Ω (max).
  • On-Resistance Flatness: 0.35Ω (max).
  • Single +1.8V to +5.5V Supply Voltage.
  • -70dB (typ) Crosstalk (20kHz).
  • -80dB (typ) Off-Isolation (20kHz).
  • 0.02% (typ) Total Harmonic Distortio.

MAX4908/MAX4909/ MAX4930/MAX4932 Dual 3:1 Clickless Audio Multiplexers with Negative-Signal Handling General Description The MAX4908/MAX4909/MAX4930/MAX4932 dual 3:1 clickless audio multiplexers feature negative-signal capability that allows signals as low as VCC - 5.5V to pass through without distortion. These analog multiplexers have a low on-resistance (0.38Ω), low supply current, and operate from a single +1.8V to +5.5V supply. The MAX4908 has shunt resistors on all input terminals, and the MAX4909 has shunt resistors on all input terminals except X0 and Y0. The MAX4930 has shunt resistors only on the X2 and Y2 terminals, and the MAX4932 has no shunt resistors.
