MAXIM MAX321ESA

MAX320/MAX321/MAX322 are precision dual-channel SPST analog switches designed for dual-supply operation from ±3V to ±8V. The MAX320 features two normally open (NO) switches, while the MAX321 features two normally closed (NC) switches. The MAX322 features one NO switch and one NC switch. Low power consumption (1.25mW) makes these devices ideal for battery-powered equipment. They offer low leakage current (100pA max) and fast switching speeds (tON = 150ns max, tOFF = 100ns max).

When the MAX320 family is powered from ±5V supplies, it provides an on-resistance (RON) of 35Ω max, channel-to-channel matching of 2Ω max, and RON flatness of 4Ω max.

These switches also provide charge injection of 5pC max and ESD protection of at least 2000V (per Method 3015.7).
