General Description

The MAX4621/MAX4622/MAX4623 are precision, dual,

high-speed analog switches. The single-pole/single-

throw (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 5

on-resistance guaranteed to

match to within 0.5

between channels and to remain

flat over the full analog signal range (

0.5

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 appli-

cations 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, respective-

ly, offering improved overall performance. These mono-

lithic 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.

Pin Description

Applications Information

Operation with Supply Voltages 

Other than ±15V

The MAX4621/MAX4622/MAX4623 switches operate with

±4.5V to ±18V bipolar supplies and a +4.5V to +36V sin-

gle supply. In either case, analog signals ranging from 

V+ to V- can be switched. The 

Typical Operating

Characteristics graphs show the typical on-resistance

variation with analog signal and supply voltage.

Overvoltage Protection

Proper power-supply sequencing is recommended for all

CMOS devices. It is important not to exceed the absolute

maximum ratings because stresses beyond the listed rat-

ings may cause permanent damage to the devices.

Always sequence V+ on first, followed by V

L

, V-, and

logic inputs. If power-supply sequencing is not possible,

add two small signal diodes in series with the supply pins

and a Schottky diode between V+ and V

L

(Figure 1).

Adding diodes reduces the analog signal range to 1V

below V+ and 1V above V-, but low switch resistance and

low leakage characteristics are unaffected. The differ-

ence between V+ and V- should not exceed +44V.
