ADS7279IPWG4

Analog To Digital Converters (ADC) Overview

The ADS7279IPWG4 is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and operates with a sampling rate of 1 MSPS. The device utilizes an SPI-compatible serial interface for data communication. It requires separate analog and digital power supplies, typically 5 V and 3.3 V respectively. Key performance metrics include a signal-to-noise ratio of 85.9 dB and differential/integral nonlinearity of +/- 1 LSB. The component is housed in a TSSOP-16 package and supports daisy-chainable operation.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clock sources
• Daisy-chainable architecture allows multiple devices to be connected on a single bus
• Low power consumption design suitable for battery-operated applications

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence per Texas Instruments specifications. Confirm the TSSOP-16 package dimensions match the target PCB footprint. Ensure the external reference voltage requirements align with the system design, as this device uses an external reference. Check humidity sensitivity levels for proper storage and reflow soldering profiles.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 1 MSPS speed are required for single-channel applications. Consider the external reference requirement if system accuracy demands precise voltage referencing. Evaluate the TSSOP-16 package constraints against available board space. Compare power dissipation figures against thermal management capabilities in the final enclosure design.

Analog To Digital Converters (ADC) Part Context

The ADS7279 belongs to the ADS7279 family of low-power SAR ADCs from Texas Instruments. This series is designed for applications requiring moderate speed and high resolution. The IPWG4 variant specifically denotes the lead-free, RoHS-compliant version in the TSSOP-16 package. It serves as a drop-in replacement for earlier non-G4 versions within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7279IPW is the non-leaded equivalent without the G4 suffix. ADS7279IPWR offers the same functionality in a tape-and-reel package instead of tube packaging.
