It routes one common terminal to either of two independent signal paths, with a maximum on-state resistance of 35 Ohm and channel-to-channel matching within 2 Ohm. The switch handles rail-to-rail analog signals across a wide supply range: single 10 V to 30 V, or dual ±4.5 V to ±20 V. Typical applications include audio routing, data-acquisition front-end multiplexing, and test-equipment signal switching where the 0°C to 70°C commercial temperature grade fits lab or controlled-environment gear. ## On-resistance and signal integrity The 35 Ohm max on-resistance governs insertion loss and voltage division in the signal path. Off-leakage is rated at 250 pA max. ## Switching speed and charge injection Turn-on time is 175 ns max, turn-off 145 ns max, fast enough for audio sample rates and moderate-speed multiplexing. Charge injection is 3 pC typical — a transient glitch that couples onto the signal when the switch changes state. In high-impedance or precision-sampling circuits, this glitch can settle into the acquisition window; a downstream sample-and-hold or ADC may need a short delay after switching. The -85 dB crosstalk at 1 MHz means the off-channel leaks very little into the active path, preserving channel isolation in multi-input systems. ## Supply flexibility and single-rail operation The MAX319CSA+ accepts a single positive supply from 10 V to 30 V, or dual supplies from ±4.5 V to ±20 V. ## Package and footprint Housed in an 8-SOIC package (0.154-inch body width, 3.90 mm), the MAX319CSA+ is a surface-mount part. It ships in Tube form. ## Lifecycle and compliance The MAX319CSA+ is listed as Active on the manufacturer's lifecycle status, with ROHS3 compliance. For new designs, the part is a safe selection without near-term obsolescence risk. The commercial temperature range (0°C to 70°C) limits it to indoor, controlled-environment equipment — not suitable for automotive or extended industrial temperature without qualification.","metaTitle":"MAX319CSA+ Analog Devices SPDT Analog Switch, 35 Ohm, 8-SOIC","metaDescription":"MAX319CSA+ single SPDT analog switch, 35 Ohm on-resistance, -85 dB crosstalk at 1 MHz.

The MAX319CSA+ accepts a single supply from 10 V to 30 V, so a 12 V rail is well within the operating range. With a single 12 V supply, the switch passes analog signals from ground up to approximately 12 V. For bipolar signals, use the dual-supply connection (±4.5 V to ±20 V)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX319CSA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX319CSA when reusing this data.
