ADC78H90CIMT

Analog To Digital Converters (ADC) Overview

The ADC78H90CIMT is a specialized data acquisition system-on-chip manufactured by Texas Instruments. It integrates four simultaneous-sampling 12-bit Analog-to-Digital Converters (ADCs) and two Digital-to-Analog Converters (DACs). The device supports a maximum sampling rate of 500 kS/s per converter channel. It operates within an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. The component utilizes a serial SPI interface for communication and is housed in a 48-pin TQFP package. It functions as a complete monitoring solution with integrated multiplexers and sample-and-hold circuits.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMT' against the manufacturer's official datasheet to confirm the package type, temperature range, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 48-pin TQFP package. Confirm that the required operating voltage levels match the specified 2.7 V to 5.25 V ranges for both analog and digital supplies before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling across multiple channels is critical for phase accuracy. Compare performance against single-converter solutions if channel count requirements are lower. Verify that the 12-bit resolution and 500 kS/s speed meet the application's bandwidth and precision needs. Consider the integrated DAC functionality for closed-loop control applications without external components.

Analog To Digital Converters (ADC) Part Context

The ADC78H90 belongs to the ADC78H8x family of specialized data acquisition devices from Texas Instruments. These chips are designed to reduce board space and component count by integrating multiple converters and peripheral functions. The CIMT variant specifically denotes the commercial temperature range and TQFP packaging option within this product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC78H89 is a related device in the same family but offers different channel configurations and pinouts. Verify pin compatibility and functional equivalence before substitution. Other members of the ADC78Hxx series may share similar interfaces but differ in resolution or channel count.
