ADS7067IYBHT

Analog To Digital Converters (ADC) Overview

The ADS7067IYBHT is an eight-channel, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 800 kSPS with single-ended inputs. The device features a wide analog supply range of 3 V to 5.5 V and a digital supply range of 1.65 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 85.3 dB, differential nonlinearity (DNL) of 0.4 LSB, integral nonlinearity (INL) of 1 LSB, and gain error of 0.01% FSR. It consumes 5 mW of power and communicates via an SPI interface. The component is housed in a WCSP-16 package and supports operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Eight-channel 16-bit SAR ADC with 800 kSPS sampling rate
• Wide voltage compatibility: Analog 3 V–5.5 V, Digital 1.65 V–5.5 V
• High accuracy: SNR 85.3 dB, INL 1 LSB, DNL 0.4 LSB
• Compact WCSP-16 package with daisy-chainable SPI interface

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel precision
• Medical instrumentation and portable diagnostic devices
• Data acquisition systems for sensor interfaces
• Battery-powered equipment due to low power consumption

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'HT' corresponds to the intended tape-and-reel packaging configuration as defined by Texas Instruments. Confirm that the WCSP-16 footprint matches the design layout, as this small outline package requires precise PCB soldering techniques. Ensure the development environment supports the required SPI protocol and voltage levels for both analog and digital domains.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7067IYBHT when high channel count and moderate speed are required alongside 16-bit resolution. Compare against the ADS7066 series if lower power (4 mW) and higher SNR (91.9 dB) are prioritized over sampling speed (250 kSPS). Verify that the single-ended input requirement aligns with the system's signal sources, as differential inputs are not supported by this specific part number.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS706x family of low-power, high-speed ADCs. It shares architectural similarities with the ADS7066 but offers a higher sampling rate of 800 kSPS compared to the ADS7066's 250 kSPS. The family is designed for applications needing multiple channels in a compact form factor, utilizing a common SPI interface and similar pinout structures across variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7066IYBHT is a related variant within the same family, offering 250 kSPS speed and 91.9 dB SNR in a BGA-16 package. Direct substitution requires verifying package compatibility (WCSP-16 vs. BGA-16) and assessing whether the reduced sampling rate or improved SNR meets the application requirements.
