ADS774JU/1K

Analog To Digital Converters (ADC) Overview

The ADS774JU/1K is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 125 kS/s and supports single-ended input signals via a parallel interface. The device functions within an analog and digital supply voltage range of 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 72 dB and a signal-to-noise and distortion ratio of 68 dB. Integral nonlinearity is specified at +/- 1 LSB. Power consumption is rated at 75 mW, with maximum power dissipation of 120 mW. It includes an internal reference and operates between -40°C and +85°C in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference to simplify circuit design.
• Features microprocessor-compatible parallel interface for direct system connection.
• Utilizes CMOS sampling architecture for efficient high-speed conversion.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1000 units as per distributor specifications. Confirm RoHS compliance status through official documentation before integration. Ensure the SOIC-28 footprint matches the target PCB layout requirements. Check for moisture sensitivity level ratings if reflow soldering is planned.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended, 12-bit SAR ADC with parallel output is required. Compare against ADS774KU for tube packaging alternatives. Consider ADS774HIBDWR if tighter integral nonlinearity specifications are necessary. Verify that the 125 kS/s sampling rate meets the application bandwidth needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS774 series of microprocessor-compatible sampling CMOS A/D converters. It shares architectural similarities with other devices in the family but differs in packaging and specific ordering suffixes. The series is designed for applications demanding moderate speed and resolution with low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

ADS774KU serves as a functional equivalent with identical electrical characteristics but utilizes tube packaging instead of reel. ADS774HIBDWR offers improved linearity performance but may require verification of pin compatibility and supply voltage ranges.
