ADS7279IPWR

Analog To Digital Converters (ADC) Overview

The ADS7279IPWR is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) 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 (SNR) of 85.9 dB and a signal-to-noise and distortion ratio (SINAD) of 85.7 dB. Differential nonlinearity (DNL) and integral nonlinearity (INL) are both specified at +/- 1 LSB. The component is housed in a TSSOP-16 package and supports daisy-chaining capabilities.

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
• Single-channel SAR structure provides high-resolution conversion

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition modules
• Battery-powered sensing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'PW' corresponds to the TSSOP-16 package and 'R' indicates tape and reel packaging when ordering. Confirm that the specific revision level matches the design requirements. Ensure compatibility with the system's voltage levels for both analog and digital domains. Check for moisture sensitivity handling requirements during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 14-bit resolution is required with a 1 MSPS throughput. It is appropriate for designs needing low power dissipation and integrated clocking. Consider the TSSOP-16 footprint constraints. Verify that single-ended inputs meet the application signal requirements rather than differential configurations.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7279 family of low-power ADCs from Texas Instruments. The IPWR variant specifically denotes the plastic TSSOP-16 package with reel packaging. It shares core specifications with the tube-packaged ADS7279IPW but differs in shipping format. The family is designed for general-purpose high-resolution data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same series include the ADS7279IPW, which offers identical electrical characteristics but in tube packaging. Other members of the ADS727x family may share functional similarities but require verification of package type and specific performance parameters before substitution.
