MAX385集成电路（IC）的模拟开关多路复用器解复用器规格书PDF中文资料

General Description

The MAX381/MAX383/MAX385 are precision, low-volt age analog switches. The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open. The single-pole double throw MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance (less than 35Ω), guaranteed to match to within 2Ω between channels and to remain flat over the specified analog signal range (4Ωmax). They also offer low leak age (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 100ns).
