ADS774KU

Analog To Digital Converters (ADC) Overview

The ADS774KU 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 inputs. 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 +/- 0.5 LSB. Power consumption is rated at 75 mW, with a maximum power dissipation of 120 mW. It utilizes a parallel interface and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm packaging type. The standard ADS774KU typically arrives in tubes, while variants like ADS774KU/1K are supplied in reels. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement to ensure compatibility with assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required with a sampling speed up to 125 kS/s. Ensure the application supports parallel interface timing constraints. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture. Consider the SOIC-28 package dimensions for PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

The ADS774KU belongs to the ADS774 series of CMOS A/D converters from Texas Instruments. This family focuses on microprocessor-compatible designs with integrated features to reduce external component count. The KU variant specifically denotes the tube-packaged version of the 28-SOIC device, distinguishing it from reel-packaged alternatives within the same electrical specification set.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same series may include ADS774KU/1K for reel packaging or ADS774KUE4 for lead-free specifications. Verify that any substitute maintains the 125 kS/s sampling rate and 12-bit resolution without altering the parallel interface timing characteristics.
