ADC78H89CIMTX

Analog To Digital Converters (ADC) Overview

The ADC78H89CIMTX is a single successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a resolution of 12 bits and supports up to seven single-ended analog inputs via an integrated multiplexer and sample-and-hold circuit. The device operates with a sampling rate of 500 ksps and accepts supply voltages ranging from 2.7V to 5.25V for both analog and digital domains. Data transfer is facilitated through a standard SPI-compatible interface suitable for DSP applications. The component is housed in a 16-TSSOP package with a width of 4.40mm and is rated for operation within a temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 7-channel multiplexer with a sample-and-hold stage directly preceding the SAR ADC core.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation, as variations such as NOPB may indicate RoHS compliance or packaging differences without altering electrical function. Confirm availability status, as original part numbers may be superseded by updated revisions. Ensure the selected variant matches the required thermal and voltage specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate channel count and 12-bit resolution are required at 500 ksps. Compare against the ADC128S102 if eight channels and higher speed are needed. Verify that the single-ended input configuration aligns with the sensor interface requirements. Check package availability and lead times for the TSSOP-16 form factor during design-in.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC78H89 family of high-speed, low-power analog-to-digital converters. It shares architectural similarities with other members of the series but is distinguished by its specific seven-channel input configuration. The family targets applications needing efficient data acquisition with minimal external components.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct replacements like ADC78H89CIMTX/NOPB which may offer updated environmental compliance. Evaluate the ADC128S102 for pin-compatible upgrades requiring additional channels and higher throughput.
