ADS8370IRHPT

Analog To Digital Converters (ADC) Overview

The ADS8370IRHPT is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 500 kSPS per channel and features an internal reference voltage source. The device supports a single +5 V analog supply and a digital supply ranging from 2.7 V to 5.5 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 84 dB and a power consumption of 90 mW. It utilizes a serial peripheral interface (SPI) for data communication and is housed in a 28-pin HTQFP package suitable for surface mount applications.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal reference voltage eliminates the need for external precision references.
• Dual-channel architecture enables simultaneous high-speed sampling for differential or independent single-ended inputs.
• Low-power SAR design optimizes energy efficiency for battery-operated systems.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems utilizing isolated measurement channels.
• Data acquisition modules for test and measurement equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRHPT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and check for any recent lifecycle status changes before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 16-bit resolution at 500 kSPS is required within a single package. Compare power consumption metrics against competing SAR ADCs if battery life is critical. Verify that the SPI interface timing aligns with the host microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS837x family of low-power, dual-channel SAR ADCs. It shares architectural similarities with other members like the ADS8364 but offers distinct performance trade-offs regarding speed and resolution. The family is designed for applications needing multiple channels without increasing board space significantly.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may include other models within the ADS837x series, such as the ADS8364, provided that sampling rate and resolution requirements are met. Verify functional equivalence regarding input types and reference configurations before substitution.
