ADS774HIBDW

Analog To Digital Converters (ADC) Overview

The ADS774HIBDW 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 transfer and requires an external reference voltage. It functions within a digital supply voltage range of 4.5 V to 5.5 V and achieves a signal-to-noise ratio of 72 dB. The component exhibits an integral nonlinearity of +/- 0.5 LSB and dissipates 120 mW of power. It 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 specific suffix 'IBDW' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Note that this part number may be designated as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors and check for moisture sensitivity levels prior to soldering.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 125 kS/s throughput are required for single-ended signals. Ensure the design accommodates a parallel interface and provides a stable external reference voltage. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS774H family of microprocessor-compatible ADCs. It shares core performance characteristics with other variants in the series but differs in packaging and specific operational parameters defined by its suffix. The family is designed for applications requiring moderate speed and resolution.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible substitutes within the ADS774H series. Verify if alternative packages or updated revisions from Texas Instruments offer equivalent electrical performance without redesigning the PCB layout.
