Overview
The MPC508AUG4 is a CMOS analog multiplexer manufactured by Texas Instruments. It integrates eight single-ended input channels or four differential input pairs, selectable via control logic. The device operates on a single supply voltage ranging from 4.5 V to 16 V. Key electrical specifications include an on-state resistance of 75 ohms maximum and an on-state capacitance of 9.4 pF. It features low leakage current and supports rail-to-rail signal handling. The component is housed in a 16-pin SOIC package.
Feature Summary
- Integrates eight single-ended or four differential analog channels within a single IC
- CMOS technology ensures low power consumption and high input impedance
- Supports wide single-supply voltage operation for flexible system integration
- Rail-to-rail signal capability allows full-scale voltage range utilization
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning
- Automotive sensor interface circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with the target application environment before finalizing procurement orders.
Selection Notes
Select this component when eight single-ended inputs or four differential pairs are required in a compact form factor. Consider the 75-ohm on-resistance for signal integrity requirements. Evaluate the 9.4 pF on-state capacitance for bandwidth limitations in high-speed applications compared to lower-capacitance alternatives.
Part Context
This part belongs to the MPC508 family of analog multiplexers from Texas Instruments. It serves as a direct replacement for legacy Burr-Brown components. The device is designed for general-purpose switching applications where low distortion and high isolation are critical performance factors.
Replacement Considerations
The MPC508AU is a compatible variant within the same family. Verify pin compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets to ensure functional parity regarding channel count and package dimensions.
