Overview
The PS320ESA is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Diodes Incorporated. It operates within a supply voltage range of ±2.7V to ±8V and features a maximum on-resistance of 35 ohms with a channel-to-channel matching of 300 milliohms. The device exhibits a maximum charge injection of 8 picocoulombs and leakage current of 100 picoamperes. Switching times are specified at 150 nanoseconds for turn-on and 100 nanoseconds for turn-off. It provides -85dB crosstalk at 1MHz and functions across an ambient temperature range of -40°C to 85°C in an 8-SOIC package.
Feature Summary
- Dual SPST configuration providing two independent signal paths
- Low on-resistance with tight channel matching for precision applications
- Minimal charge injection and low leakage current for signal integrity
- Wide dual-supply operation capability
Applications
- Signal routing in data acquisition systems
- Multiplexing audio or video signals
- Programmable gain amplifier circuits
- Sample-and-hold circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as the specific listing indicates non-compliance. Check for End-of-Life notices or Product Change Notifications regarding manufacturing discontinuation before finalizing procurement plans.
Selection Notes
Select this component when dual isolated analog switching is required with low distortion characteristics. Ensure the application voltage stays within the ±2.7V to ±8V limit. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify thermal management requirements against the specified operating temperature range.
Part Context
This part belongs to the PS320 series of analog switches from Diodes Incorporated, formerly associated with Pericom Semiconductor Corporation. The series includes variants such as the PS323ESAE and PS320CPAE, offering similar switching functionalities in different package formats like PDIP-8.
Replacement Considerations
Publicly confirmed substitute part numbers include MAX320ESA+ and MAX320CSA+ from Analog Devices Inc./Maxim Integrated. These alternatives provide functional compatibility but require verification of pinout and electrical parameter alignment.
