Key Features
- Single-channel SPDT analog switch with 68 dB off-state isolation, minimizing signal crosstalk in precision analog routing and audio multiplexing circuits
- Wide dual supply range of ±4.5 V to ±20 V, also operable from a 12 V single supply, accommodating diverse analog front-end power architectures
- 8-DIP through-hole package enabling easy prototyping and hand-soldering in test fixtures and lab instruments without specialized SMT equipment
Applications
The MAX319CPA SPDT analog switch is ideal for precision signal routing in data acquisition front ends, audio switching matrices, and instrumentation amplifier input selection circuits requiring high off-state isolation of 68 dB. Its wide supply voltage range from ±4.5 V to ±20 V suits both battery-powered portable instruments and benchtop test equipment powered from ±15 V rails. The 8-DIP package simplifies prototyping on breadboards and through-hole PCBs in research and low-volume production environments.

Frequently Asked Questions
What supply voltage range does the MAX319CPA support and can it run from a single supply?
The MAX319CPA operates from a dual supply ranging from ±4.5 V to ±20 V with a nominal ±15 V rating, and also supports a 12 V nominal single supply as indicated in its specifications. This flexibility allows the MAX319CPA to interface with both classic ±15 V op-amp circuits and modern single-supply 12 V systems without redesigning the power architecture.
How does the 68 dB off-state isolation of the MAX319CPA benefit precision analog signal routing?
The MAX319CPA's 68 dB off-state isolation means that an unselected switch channel attenuates leakage signals by a factor of approximately 2500:1, which is critical in precision multiplexer circuits where a 1 V signal on an off-channel must not corrupt a 100 µV measurement on the active channel. This isolation level supports 12-bit ADC accuracy in data acquisition systems operating at signal bandwidths up to several hundred kHz.
For which laboratory and industrial signal-switching applications is the MAX319CPA 8-DIP a better fit than an SOIC version?
The MAX319CPA in 8-DIP is preferred for breadboard prototyping, socketed test fixtures, and through-hole PCB designs where hand soldering and component swapping during development are required. The 0.1 inch (2.54 mm) pin spacing of the DIP-8 package fits standard IC sockets and breadboard rails, making it convenient for laboratory signal routing, relay-replacement experiments, and low-volume industrial instruments.
What is the channel configuration of the MAX319CPA and how does it differ from a DPDT switch?
The MAX319CPA is a single-channel SPDT (single-pole double-throw) analog switch with 1 common input and 2 selectable outputs (NO and NC positions). A DPDT switch would provide 2 independent SPDT channels simultaneously; for applications requiring 2-channel switching, two MAX319CPA devices would be needed, each consuming approximately 1 mW of quiescent power from a ±15 V supply.
