The MAX320/MAX321/MAX322 a re p re c is ion, d ua l,
SPST analog switches designed to operate from ±3V to
±8V dual supplies. The MAX320 has two normally open
(NO) s witc he s a nd the MAX321 ha s two norma lly
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
