ADS1178IPAPR

Analog To Digital Converters (ADC) Overview

The ADS1178IPAPR is an octal, simultaneous sampling, 16-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a delta-sigma architecture and features eight single-ended input channels with an SPI interface. The device operates within an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 1.65 V to 1.95 V. Key performance metrics include a maximum sample rate of 52 kS/s, a signal-to-noise ratio (SNR) of 97 dB, and differential/non-linearities of +/- 1 LSB. It is housed in a 64-pin HTQFP package and supports daisy-chainable configurations for multi-device systems.

Analog To Digital Converters (ADC) Feature Summary

• Octal simultaneous sampling capability ensures precise time-alignment across all eight channels.
• Daisy-chainable architecture allows multiple devices to be connected via the SPI interface.
• Sigma-delta modulation structure provides high-resolution 16-bit data conversion.

Analog To Digital Converters (ADC) Applications

• Multi-channel data acquisition systems requiring synchronized sampling
• Industrial process control instrumentation
• Structural health monitoring networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPAPR against the manufacturer's official datasheet to confirm the HTQFP-64 package type and commercial temperature rating. Ensure that external reference components match the specified voltage requirements for optimal accuracy. Confirm humidity sensitivity handling procedures during assembly as indicated in the storage guidelines.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous channels are required at 16-bit resolution. Compare power consumption specifications against thermal constraints if operating near the upper temperature limit. Verify that the host microcontroller supports the necessary SPI clock speeds and daisy-chain logic for system integration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1178 family of octal ADCs. It shares architectural similarities with the quad-channel ADS1174 but offers double the channel count. Both devices utilize the same HTQFP-64 package and similar electrical characteristics, differing primarily in input channel density and associated power dissipation profiles.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1174IPAPR serves as a functional substitute if only four simultaneous channels are required, offering pin-compatible reduction. No other direct replacements are confirmed in the provided documentation.
