Product details

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.

Housed in an 8-SOIC package (0.154" body width, 3.90 mm), surface-mount only. Shipped in Tube — for reel quantities, confirm the tape-and-reel suffix variant with your distributor.

Frequently asked questions

What is the on-resistance of MAX322CSA+?

Maximum on-resistance is 35 Ohm, with channel-to-channel matching of 300 mOhm.

Can I use MAX322CSA+ as a replacement for DG419?

The MAX322CSA+ is a dual SPST switch with NO/NC per channel, while the DG419 is a single SPDT. Pinout and function differ — verify the application circuit before substituting.

What is the crosstalk of MAX322CSA+?

Crosstalk is rated at -85 dB at 1 MHz, ensuring good isolation between channels for analog signals.
