ADS6143IRHBT

Analog To Digital Converters (ADC) Overview

The ADS6143IRHBT is a single-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 80 MSPS using a pipeline architecture. The device features differential inputs and supports both external and internal reference types. It requires a 3.3 V analog supply and a 3 V to 3.6 V digital supply. Key performance metrics include an SNR of 74.9 dB, SFDR of 89 dB, and SINAD of 74.3 dB. DNL is +/- 2 LSB, INL is +/- 4 LSB, and ENOB is 12 bits. Power consumption is 318 mW. It uses a 3-wire interface with LVDS output in a 32-lead VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RHBT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the operating temperature range meets the -40°C to +85°C specification for industrial environments. Ensure compatibility with the 3.3V analog and 3V-3.6V digital power domains during board design validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between high resolution and moderate speed is required. The 80 MSPS rate suits applications not needing the higher speeds of the 125 MSPS variant but demanding better dynamic range than lower-speed models. Consider the VQFN-32 package size constraints and thermal dissipation capabilities relative to the 318 mW power draw.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS6143 series, which offers variable sampling rates including 125, 105, 80, and 65 MSPS. The IRHBT designation indicates the specific 80 MSPS version housed in a leadless VQFN package suitable for surface-mount technology. It is designed for applications requiring high linearity and low power in a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6142IRHBT is a related 14-bit ADC but operates at 65 MSPS with different interface options. The ADS6125IRHBR is a 12-bit, 125 MSPS alternative. Verify pinout and software compatibility before substituting, as interface protocols and performance characteristics differ significantly between these variants.
