ADS7066IYBHR

Analog To Digital Converters (ADC) Overview

The ADS7066IYBHR is a Texas Instruments 16-bit, 8-channel successive-approximation register (SAR) analog-to-digital converter. It operates with an analog supply of 3 V to 5.5 V and a digital supply of 1.65 V to 5.5 V. The device supports a maximum sampling rate of 250 kSPS with no latency. Key electrical parameters include a signal-to-noise ratio of 91.9 dB, integral nonlinearity of ±1 LSB, and differential nonlinearity of ±0.4 LSB. It features an enhanced SPI interface supporting up to 60 MHz clock speeds. The component is housed in a 16-pin DSBGA package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'HR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the YBH package designation matches the intended board layout dimensions. Ensure the selected variant meets the necessary temperature range specifications for the target operating environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high channel count and mixed-signal flexibility are required within a compact footprint. The integrated GPIO capability simplifies circuit design by allowing digital control feedback without additional logic components. Consider the low power consumption characteristics if battery-operated systems are involved. Verify that the 250 kSPS throughput aligns with the system's real-time processing requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7066 family of high-precision SAR ADCs. It shares architectural similarities with the ADS7067, which offers a higher sampling speed of 800 kSPS. Both devices utilize the same small form factor packages and feature sets, differing primarily in conversion speed. This model represents the standard throughput variant within the series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7066IYBHT serves as a compatible alternative offering cut-tape packaging options instead of reel packaging. Designers requiring different handling methods may substitute this part while maintaining identical electrical performance and pinout compatibility.
