What this switch is and where it fits
The Maxim Integrated MAX322CSA+ is a dual-channel SPST analog switch with both normally-open and normally-closed configurations per channel. Each switch handles rail-to-rail analog signals with a maximum on-resistance of 35 Ohm and channel-to-channel matching within 300 mOhm.
Crosstalk and charge injection — the signal integrity specs
At 1 MHz, crosstalk between channels is rated at -85 dB, which keeps a strong signal on one channel from bleeding into the other.
Package and mounting
Housed in an 8-SOIC package (0.154" body width, 3.90 mm), surface-mount only. The supplier device package is 8-SOIC. Shipped in Tube — for reel quantities, confirm the tape-and-reel suffix variant with your distributor.
Lifecycle and sourcing posture
The MAX322CSA+ carries an active lifecycle status with ROHS3 compliance. No last-time-buy or end-of-life notice is in effect. This part is sourced through independent distribution and is quoted to order against an RFQ.
