General Description

The MAX4621/MAX4622/MAX4623 are precision, dual,
high-speed analog switches. The single-pole/single­throw (SPST) MAX4621 and double-pole/single-throw
(DPST) MAX4623 dual switches are normally open
(NO). The single-pole/double-throw (SPDT) MAX4622
has two normally closed (NC) and two NO poles. All
three parts offer low 5Ω on-resistance guaranteed to
match to within 0.5Ω between channels and to remain
flat over the full analog signal range (∆0.5Ω max). They
also offer low leakage (<500pA at +25°C, <5nA at
+85°C) and fast switching times (turn-on time <250ns,
turn-off time <200ns).

These analog switches are ideal in low-distortion appli­cations and are the preferred solution over mechanical
relays in automatic test equipment or applications
where current switching is required. They have low
power requirements, use less board space, and are more
reliable than mechanical relays.

The MAX4621/MAX4622/MAX4623 are pin-compatible
replacements for the DG401/DG403/DG405, respective­ly, offering improved overall performance. These mono­lithic switches operate from a single positive supply
(+4.5V to +36V) or with bipolar supplies (±4.5V to ±18V)
while retaining CMOS-logic input compatibility.

Features

♦ Low On-Resistance: 3Ω (typ), 5Ω (max)
♦ Guaranteed RONMatch Between Channels

(0.5Ω max)

♦ Guaranteed Break-Before-Make Operation

(MAX4622)

♦ Guaranteed Off-Channel Leakage <5nA at +85°C
♦ Single-Supply Operation (+4.5V to +36V)

Bipolar-Supply Operation (±4.5V to ±18V)

♦ TTL/CMOS-Logic Compatible
♦ Rail-to-Rail®Analog Signal Handling Capability
♦ Pin Compatible with DG401/DG403/DG405

Applications

Reed Relay Replacement Military Radios
Test Equipment PBX, PABX Systems
Communication Systems Audio-Signal Routing
Data-Acquisition Systems Avionics

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
