MAX4646 - CMOS Analog Switches

Download the MAX4646 datasheet PDF. This datasheet also covers the MAX4645 variant, as both devices belong to the same cmos analog switches family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX4645/MAX4646 single-pole, single-throw (SPST) analog switches feature a 2.5Ω typical on-resistance (RON) from a +5V supply.

RON is flat (0.4Ω max) over the specified signal range.

Each switch can handle Rail-toRail® analog signals.

Features

  • +1.8V to +5V Single-Supply Operation.
  • Guaranteed RON 2.5Ω max (5V supply) 3.5Ω max (3V supply).
  • 1.8V Operation RON 30Ω typ Over Temperature tON 40ns typ, tOFF 20ns typ.
  • Low RON Flatness: 0.4Ω max.
  • Guaranteed Low Leakage Currents ±0.25nA at +25°C.
  • Rail-to-Rail Output Capability.
  • TTL/CMOS-Logic Compatible.
  • -75dB Off-Isolation at 1MHz.
  • Low Distortion: 0.014% typ Ordering Information PART MAX4645EUK-T MAX4645EUT-T MA.

19-1653; Rev 2; 2/04 MAX4645/MAX4646 Fast, Low-Voltage, 2.5Ω, SPST, CMOS Analog Switches General Description The MAX4645/MAX4646 single-pole, single-throw (SPST) analog switches feature a 2.5Ω typical on-resistance (RON) from a +5V supply. RON is flat (0.4Ω max) over the specified signal range. Each switch can handle Rail-toRail® analog signals. Off-leakage current is 0.25nA max at +25°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays. These switches operate from a +1.
