MAX383ESE

高精度，低电压模拟开关 Precision, Low-Voltage Analog Switches

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.
