Overview

  • Data and Audio Signal Routing
  • Low On-Resistance (0.5Ω) Audio Switches
  • 0.2Ω On-Resistance Flatness
  • 0.1Ω Channel-to-Channel Matching
  • Low-Capacitance (25pF) Data Switches (MAX4759)
  • 0.2ns Skew (MAX4759)
  • 0.03% THD
  • +1.8V to +5.5V Supply Range
  • Rail-to-Rail Signal Handling
  • Tiny 36-Bump UCSP (3mm x 3mm)
  • 36-Pin Thin QFN (6mm x 6mm)

The MAX4758/MAX4759 quad double-pole/double-throw (DPDT) analog switches operate from a single +1.8V to +5.5V supply. These switches feature low 0.5Ω on-resistance for audio switching and a low 25pF capacitance for data switching.

The MAX4758 has eight 0.5Ω on-resistance switches to switch audio signals. The MAX4759 has four 0.5Ω on-resistance switches to route audio signals and four 25pF capacitance switches to route data signals. The MAX4758/MAX4759 have four logic inputs to control the switches in pairs.

The MAX4758/MAX4759 are available in a small 36-pin (6mm x 6mm) thin QFN and 36-bump (3mm x 3mm) chip-scale package (UCSP™).
