ADS7067IYBHR

Analog To Digital Converters (ADC) Overview

The ADS7067IYBHR 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 supports analog supply voltages from 3 V to 5.5 V and digital supplies from 1.65 V to 5.5 V. Key electrical specifications 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. Power consumption is rated at 5 mW. It features SPI interface, daisy-chain capability, GPIOs, and operates within a temperature range of -40°C to +125°C in a WCSP-16 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'HR' against the manufacturer's official datasheet to confirm tape-and-reel packaging details and any functional differences compared to the 'HT' variant. Ensure compatibility with the target PCB footprint for the WCSP-16 package. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as these factors are subject to change.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7067IYBHR when high channel count (8 channels) and resolution (16-bit) are required alongside moderate speed (800 kSPS). Consider this part for applications needing low power dissipation (5 mW) and wide input voltage ranges. Verify that the single-ended input configuration meets system requirements, as differential inputs are not supported. Ensure the SPI interface timing aligns with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

The ADS7067 belongs to the ADS706x family of multi-channel SAR ADCs. It shares architectural similarities with the ADS7066 but offers a higher sampling rate (800 kSPS vs. 250 kSPS). Both devices feature 16-bit resolution and eight channels. The 'I' grade indicates an extended industrial temperature range (-40°C to +125°C). The 'YB' package code denotes the WCSP-16 form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7066IYBHR is a compatible alternative within the same family, offering identical resolution and channel count but with a lower maximum sampling rate of 250 kSPS. Designers requiring higher throughput should stick with the ADS7067. Other members of the ADS706x series may serve as replacements if pinout and software compatibility are verified.
