ADS1178IPAPT

Analog To Digital Converters (ADC) Overview

The ADS1178IPAPT is an octal, simultaneous sampling, 16-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a sigma-delta architecture and features eight single-ended input channels with an SPI interface. The device operates at a maximum sample rate of 52 kS/s per channel. Electrical specifications include a signal-to-noise ratio (SNR) of 97 dB, with differential and integral nonlinearity both specified at +/- 1 LSB. Power requirements consist of 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. Typical power consumption is 245 mW, with a maximum power dissipation of 355 mW. The component is housed in an HTQFP-64 package and supports operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Octal simultaneous sampling capability for synchronized multi-channel acquisition
• Daisy-chainable architecture for simplified system interconnects
• High linearity performance with +/- 1 LSB DNL and INL specifications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high channel count data acquisition
• Medical instrumentation such as ECG and EEG monitoring equipment
• Seismic data acquisition and geophysical surveying instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPAPT against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with external reference voltages and SPI bus levels before integration. Confirm RoHS compliance status through current manufacturer datasheets or notices. Validate that the HTQFP-64 footprint matches the design layout requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous sampling channels are required rather than sequential multiplexed inputs. Compare power consumption metrics against thermal constraints in the target enclosure. Evaluate the need for daisy-chaining capabilities if multiple ADCs are used in the system architecture. Verify that the 16-bit resolution and 52 kS/s speed meet the application bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

The ADS1178 belongs to the ADS117x family of 16-bit simultaneous sampling ADCs from Texas Instruments. This series includes variants with different channel counts, such as the quad-channel ADS1174. All members share similar architectural features including sigma-delta conversion and SPI interfaces. The IPAPT designation specifically indicates the surface-mount HTQFP-64 package with reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1174 serves as a lower-channel-count alternative within the same family. Verify pinout compatibility and software register settings when substituting between octal and quad variants. Check for any differences in power consumption or thermal characteristics between specific part numbers.
