ADC78H90CIMTX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC78H90CIMTX/NOPB is a high-performance, low-power analog-to-digital converter featuring a 12-bit resolution and an integrated sample-and-hold circuit. It supports eight single-ended input channels with a sampling rate of 500 kSPS. The device utilizes a successive approximation register (SAR) architecture and operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. It communicates via a standard SPI-compatible interface and is housed in a 16-TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with a dedicated sample-and-hold stage preceding the SAR ADC core.
• Supports flexible data output formats compatible with standard DSP and microcontroller interfaces.
• Operates within a wide single-supply voltage range suitable for battery-powered applications.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify that the suffix NOPB indicates lead-free packaging compliant with RoHS standards. Confirm the CIMTX designation corresponds to the TSSOP-16 surface-mount package variant. Ensure the specific ordering code matches the required tape-and-reel quantity for manufacturing integration. Cross-reference the manufacturer datasheet for any recent pinout or electrical specification updates prior to final procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous single-ended inputs are required at moderate speeds. The integrated sample-and-hold simplifies PCB layout by reducing external component count. Compare against the ADC78H89 if only seven channels are needed. Consider the ADC10040 series for higher throughput requirements despite its parallel interface complexity. Verify power supply constraints align with the specified 2.7V to 5.25V operating range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADC78Hxx family of 12-bit SAR converters. It shares architectural similarities with the ADC78H89 but provides an additional input channel. The device complements the company's portfolio of low-power data converters designed for embedded sensing applications requiring moderate resolution and speed.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC78H89CIMTX/NOPB serves as a direct substitute for designs utilizing only seven channels. For applications requiring higher performance, the ADC78H90CIMTX may be considered if available. Verify pin compatibility before swapping between these variants.
