ADS8166IRHBR

Analog To Digital Converters (ADC) Overview

The ADS8166IRHBR is an eight-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 250 kSPS and utilizes a VQFN-32 package for surface-mount installation. The device accepts pseudo-differential or single-ended inputs and communicates via an SPI interface. It requires a 5 V analog supply and a 3 V digital supply. Key performance metrics include a signal-to-noise ratio of 93.6 dB, a spurious-free dynamic range of 112 dB, and a full-power bandwidth supporting high-speed acquisition. Nonlinearity specifications are defined by a differential nonlinearity of 0.2 LSB and integral nonlinearity of 0.35 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with required supply voltages and interface protocols before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous channels are required within a compact footprint. The 16-bit resolution and 250 kSPS speed balance precision with throughput for general-purpose applications. Consider the external reference requirement if higher accuracy than the internal option is necessary for the specific application environment.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS816x family of high-speed, low-power SAR ADCs from Texas Instruments. The family shares architectural similarities but varies in channel count and sampling rates. The IRHBR suffix indicates the industrial temperature range and the specific VQFN-32 reel packaging configuration used for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8168 serves as a pin-compatible alternative within the same family, offering similar functionality with potential differences in sampling speed or reference integration. Verify electrical parameters and pin assignments against official datasheets before substitution.
