19-0300; Rev 0; 9/94 Precision, Low-Voltage Analog Switches _______________General Description The MAX381/MAX383/MAX385 are precision, low-voltage analog switches.
The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open.
The single-pole doublethrow MAX383 has two normally open and two normally closed poles.
All three parts offer low on-resistance (less than 35 Ω ), guaranteed to match to within 2 Ω between channels and to remain flat over the specified analog signal range (4Ω max).
They also offer low leakage (less than 250pA at +25°C and less than 2.
5nA at +85°C) and fast switching (turn-on time less than 175ns and turn-off time less than 100...
