ADS774KU/1K

Analog To Digital Converters (ADC) Overview

The ADS774KU/1K is a single-channel, 12-bit Analog-to-Digital Converter (ADC) from Texas Instruments' ADS774 series. It utilizes a Successive Approximation Register (SAR) architecture with a sampling rate of 125 kS/s and accepts single-ended inputs. The device operates on both analog and digital power supplies ranging from 4.5 V to 5.5 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 72 dB, a SINAD of 68 dB, and an Integral Nonlinearity (INL) of +/- 0.5 LSB. It features an internal reference and is housed in a SOIC-28 package, operating within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference to simplify circuit design.
• Supports parallel interface for high-speed data transfer.
• Delivers precise conversion accuracy with low integral nonlinearity.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix /1K confirms the reel packaging format when sourcing. Confirm that the required quantity aligns with the manufacturer's standard reel size. Ensure the component meets RoHS compliance requirements for the intended assembly process. Cross-reference the datasheet revision to guarantee pinout and electrical characteristics match the design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single-channel SAR ADC with integrated reference capabilities. The 12-bit resolution and 125 kS/s speed suit moderate bandwidth needs. Verify that the system can accommodate the parallel interface protocol. Ensure the 4.5 V to 5.5 V supply range matches the available power rails in the target design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS774 family of CMOS sampling ADCs. It shares architectural similarities with other members like the ADS774KU but differs in packaging and reel configuration. The /1K suffix specifically denotes the tape-and-reel delivery method, distinguishing it from tube-packaged variants such as the ADS774KU.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS774KU for tube packaging. Verify compatibility regarding the parallel interface timing and power supply requirements before swapping packages.
