DG441 - SPST Analog Switches

Description

Maxim’s redesigned DG441/DG442 analog switches now feature on-resistance matching (4Ω max) between switches and guaranteed on-resistance flatness over the signal range (9Ω max).

These low on-resistance switches conduct equally well in either direction.

Features

  • Plug-In Upgrades for Industry-Standard DG441/DG442.
  • Improved rDS(ON) Match Between Channels(4Ωmax).
  • Guaranteed rFLAT(ON) Over Signal Range (9Ωmax).
  • Improved Charge Injection (10pC max).
  • Improved Off-Leakage Current Over Temperature (.

19-4611; Rev 5; 5/09 Improved, Quad, SPST Analog Switches DG441/DG442 General Description Maxim’s redesigned DG441/DG442 analog switches now feature on-resistance matching (4Ω max) between switches and guaranteed on-resistance flatness over the signal range (9Ω max). These low on-resistance switches conduct equally well in either direction. They guarantee low charge injection (10pC max), low power consumption (1.65mW), and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers lower off-leakage current over temperature (less than 5nA at +85°C). The DG441/DG442 are quad, single-pole/single-throw (SPST) analog switches. The DG441 has four normally closed switches, and the DG442 has four normally open switches.
