Quad SPST Analog Switch with Wide Supply Range
The Maxim Integrated DG413DY+ is a quad single-pole single-throw (SPST) analog switch configured as two normally open (NO) and two normally closed (NC) channels in a 16-SOIC package. Each switch presents a maximum on-resistance of 45 Ohm, with channel-to-channel matching within 3 Ohm, making it suitable for precision analog signal routing where path resistance consistency matters.
Supply Voltage Versatility and Signal Integrity
This switch operates from a single supply of 10 V to 30 V or dual supplies of ±4.5 V to ±20 V, covering common industrial and test-equipment rails. The -85 dB crosstalk at 1 MHz keeps channel bleed low in multi-channel data acquisition or audio routing. Charge injection is rated at 5 pC, and off-leakage current is a maximum 250 pA, preserving signal accuracy in high-impedance circuits.
Switching Speed and Capacitance
Maximum turn-on time is 175 ns and turn-off time is 145 ns, allowing fast channel switching in multiplexed systems. Channel capacitance (both source off and drain off) is 9 pF, which helps maintain signal bandwidth and reduces settling time in sample-and-hold stages.
Industrial Temperature Grade and Package
Rated for -40°C to 85°C operating temperature, the DG413DY+ suits industrial control, instrumentation, and telecom environments where ambient temperature swings are routine. The 16-SOIC package (0.154" width, 3.90 mm body) is a common footprint for automated assembly and rework.
Sourcing and Lifecycle
The DG413DY+ is listed as Active and ROHS3 compliant. It remains a current-production part, available through independent distribution channels. Pricing and availability are confirmed at quote time against an RFQ — no stock or price figures are published here.
