Overview
The DG408DY/R70865 is an improved CMOS analog multiplexer switch manufactured by Analog Devices Inc. (Maxim Integrated). It features a single 8:1 configuration housed in a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±5V to ±20V. Key electrical specifications include a maximum on-resistance of 100 Ohms, a channel-to-channel matching of 1.5 Ohms, and a charge injection of 2pC. Switching times are limited to 150ns for both turn-on and turn-off periods. The component supports an operating temperature range of -40°C to +85°C and exhibits low off-state leakage current of 500pA.
Feature Summary
- CMOS technology ensures low power consumption and high input impedance.
- Improved performance characteristics including reduced charge injection and on-resistance compared to previous generations.
- Single 8:1 multiplexing architecture allows selection of one input from eight channels.
Applications
- Data acquisition systems requiring signal routing.
- Industrial process control instrumentation.
- Medical equipment signal conditioning.
Procurement Notes
Verify the specific suffix R70865 against official manufacturer documentation to confirm it denotes a standard tape-and-reel packaging variant or a specific customer code. Ensure compatibility with RoHS directives if required for your application. Cross-reference the base part number DG408DY to confirm pinout and electrical parameters remain consistent across packaging variations.
Selection Notes
Select this component when an 8-channel analog switch with low on-resistance and fast switching speeds is required. The wide supply voltage range accommodates various logic levels. Consider the SOIC-16 package constraints for PCB layout. Verify that the 100 Ohm on-resistance meets the signal integrity requirements of the specific application circuit.
Part Context
This part belongs to the DG408 series of improved CMOS analog switches. It serves as a successor to earlier discrete or less integrated solutions, offering enhanced performance metrics such as lower charge injection and tighter on-resistance matching. The series is designed for applications demanding reliable analog signal routing in compact form factors.
Replacement Considerations
Direct replacements include the DG408CY+ and DG408EUE+. Verify package compatibility (SOIC vs TSSOP) and ensure electrical parameters like on-resistance and supply voltage ranges match the original design requirements.
