ADS774HIBDWR

Analog To Digital Converters (ADC) Overview

The ADS774HIBDWR 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. The device utilizes a parallel interface for data communication and requires an external reference voltage. It functions on a 5 V analog supply and a digital supply range of 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 72 dB and an integral nonlinearity of +/- 0.5 LSB. The component is housed in a 28-pin SOIC package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the lifecycle status before integration, as this specific part number may be marked as Not Recommended for New Designs. Confirm that the required packaging format matches the available reel or cut tape options. Ensure the design accommodates the specified humidity sensitivity等级 during storage and assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 125 kS/s throughput are sufficient for the application. Choose the external reference configuration if higher precision than the internal option allows. Verify that the system logic levels align with the 4.5 V to 5.5 V digital supply requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS774H series of microprocessor-compatible sampling CMOS A/D converters. It shares architectural similarities with other members like the ADS774KU but differs in specific packaging and reference configurations. The series is designed for applications requiring moderate speed and resolution with direct CPU interfacing capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Consider the ADS774KU or ADS774KUE4 for equivalent functional performance. Note that these alternatives may differ in packaging type, such as tube versus reel, or internal reference availability. Verify pin compatibility and electrical specifications before substitution.
