ADS774HIDW

Analog To Digital Converters (ADC) Overview

The ADS774HIDW 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. It requires an analog supply voltage of 5 V and a digital supply voltage ranging from 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 SOIC-28 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-28 tube packaging configuration. Confirm that the part status aligns with current design requirements, as availability may vary. Ensure compatibility with the required 5V logic levels and parallel bus timing specifications before integration into the final system design.

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. It is suitable for designs requiring a parallel interface rather than serial alternatives. Consider the SOIC-28 footprint constraints and the need for separate analog and digital power supplies during the schematic layout phase.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS774H series of microprocessor-compatible ADCs. It shares architectural similarities with other members like the ADS774KU but differs in packaging and specific electrical characteristics such as power dissipation profiles. The series targets applications needing moderate speed and resolution with direct CPU interfacing capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS774KU offers similar electrical performance in a different package option. Verify pinout compatibility and thermal requirements when substituting between these variants.
