ADC14X250RHBT

Analog To Digital Converters (ADC) Overview

The ADC14X250RHBT is a monolithic single-channel high-performance analog-to-digital converter (ADC) manufactured by Texas Instruments. It converts analog input signals into digital words with a resolution of 14 bits and a sampling rate of 250 MSPS. The device utilizes a differential pipeline architecture with an integrated input buffer to eliminate charge injection noise from the internal switched-capacitor sampling circuit. It operates on three power supplies: 1.2 V, 1.8 V, and 3.0 V. The component provides a JESD204B Class 1 single-channel serial interface supporting channel rates up to 5 Gb/s. Key performance metrics include a signal-to-noise ratio (SNR) of 70.1 dBFS at 240 MHz input, a spurious-free dynamic range (SFDR) of 87 dB, and a typical power consumption of 584 mW.

Analog To Digital Converters (ADC) Feature Summary

• Integrated low-noise reference voltage source simplifies board-level design by eliminating the need for external decoupling capacitors.
• Input sampling clock divider supports integer division ratios of 1, 2, 4, and 8 to simplify system clocking requirements.
• Buffer adjustment capabilities correct phase and amplitude imbalances in the differential input signal path to improve even-order harmonic distortion.
• Four-wire serial peripheral interface (SPI) allows configuration with logic levels compatible from 1.2 V to 3 V.

Analog To Digital Converters (ADC) Applications

• Communication systems requiring high-speed digitization
• Radar applications demanding precise dynamic performance
• Test and measurement equipment operating in extended temperature ranges
