VECANA01G3

Overview

The VECANA01G3 is a 10-channel, 12-bit data acquisition system manufactured by Texas Instruments. Housed in a 68-pin PLCC (LCC-68) package, this analog-to-digital converter subsystem supports an analog input voltage range of -2.5 V to +2.5 V. The device features a maximum conversion time of 10.4 µs and a maximum linear error of 0.0488%. It operates with a nominal negative supply voltage of -5 V and is RoHS compliant. The component is designed for applications requiring multi-channel signal acquisition with moderate speed and precision.

Feature Summary

• 10-channel simultaneous or sequential data acquisition capability
• 12-bit resolution with 0.0488% maximum linear error
• 10.4 µs maximum conversion time per channel
• 68-pin Plastic Leaded Chip Carrier (PLCC) surface-mount package

Applications

• Industrial process control systems
• Data logging equipment
• Multi-sensor measurement interfaces

Procurement Notes

Verify the specific suffix 'G3' against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid RoHS compliance certificates as indicated in the component parameters. Cross-reference the JESD-30 code S-PQCC-J68 to confirm physical package dimensions match design requirements.

Selection Notes

Select this component when a fixed 10-channel, 12-bit ADC solution is required without external multiplexing. The -5 V nominal supply requirement must be accommodated in the power design. Consider the 68-pin PLCC package constraints for PCB layout and thermal management. Verify that the 10.4 µs conversion speed meets the system's throughput requirements for all ten channels.

Part Context

The VECANA01 series represents a family of integrated data acquisition systems from Texas Instruments. The VECANA01G3 is a specific variant within this line, offering a balance of channel count and resolution. It serves as a complete ADC subsystem, reducing the need for external analog front-end components in multi-channel sensing applications.

Replacement Considerations

Direct replacements should maintain 10-channel, 12-bit performance and similar supply voltage requirements. Verify pin-to-pin compatibility if substituting within the same package type. Check datasheets for equivalent conversion speeds and linear error specifications to ensure functional parity.
