The MAX320/MAX321/MAX322 are precision, dual,

SPST analog switches designed to operate from ±3V to

±8V dual supplies. The MAX320 has two normally open

(NO) switches and the MAX321 has two normally

closed (NC) switches. The MAX322 has one NO and

one NC switch. Low power consumption (1.25mW)

makes these parts ideal for battery-powered equip-

ment. They offer low leakage currents (100pA max) and

fast switching speeds (t

max).

The MAX320 series, powered from ±5V supplies, offers

35Ω max on-resistance (R

between channels, and 4Ω max R

These switches also offer 5pC max charge injection

and a minimum of 2000V ESD protection per Method

3015.7.

For equivalent devices specified for single-supply oper-

ation, see the MAX323/MAX324/MAX325 data sheet.

For quad versions of these switches, see the

MAX391/MAX392/MAX393 data sheet.
