ADS1274IPAPTG4

Analog To Digital Converters (ADC) Overview

The ADS1274IPAPTG4 is a quad-channel, simultaneous-sampling analog-to-digital converter manufactured by Texas Instruments. It features a 24-bit resolution and utilizes sigma-delta architecture to achieve high precision. The device supports data rates up to 144 kS/s per channel with a signal-to-noise ratio of 111 dB. It operates with an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 1.65 V to 2.2 V. The component is housed in a 64-pin HTQFP package and includes daisy-chainable serial interfaces. It functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all four channels ensures precise phase alignment for multi-channel applications.
• Daisy-chainable SPI interface allows multiple devices to be connected using a single serial port.
• Integrated programmable gain amplifier provides flexibility for varying input signal amplitudes.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-precision multi-channel data acquisition
• Seismic data acquisition equipment for geological surveying
• High-fidelity audio measurement and analysis instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance when sourcing this component. Confirm the package type matches the design requirements as the IPAPT designation corresponds to the HTQFP-64 form factor. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number to guarantee authenticity and quality standards.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous sampling of four channels is required at high speeds. Compare against the ADS1278 if eight channels are needed instead of four. Consider the ADS1174 if lower 16-bit resolution is sufficient for the application. Verify that the external reference voltage meets the stability requirements for the specified SNR performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS127x family of high-performance data converters from Texas Instruments. It shares architectural similarities with the ADS1278 but differs in channel count. The IPAPTG4 variant specifically denotes the lead-free, halogen-free version of the standard ADS1274IPAPT industrial grade device.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1278IPAPTG4 offers identical specifications with eight channels instead of four. ADS1174IPAPTG4 provides the same package and interface but with 16-bit resolution. Direct pin-compatible alternatives should be verified against the official TI substitution guide for electrical compatibility.
