ADC122S655CIMM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S655CIMM/NOPB is a dual-channel, 12-bit simultaneous sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at sampling rates between 200 kSPS and 500 kSPS using a successive approximation register (SAR) architecture. The device features differential inputs with excellent common-mode rejection and an external reference input ranging from 1.0 V to VA. It supports serial interfaces including SPI, QSPI, Microwire, and DSP standards via a single high-speed data output. Power consumption is typically 11 mW at 500 kSPS with a 5 V supply, dropping to 3 μW in shutdown mode. It functions within an industrial temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Feature Summary

• True simultaneous sampling preserves phase information between channels
• Differential input structure maintains signal integrity through internal tracking and holding circuits
• Single serial data output compatible with multiple standard digital signal processing interfaces

Analog To Digital Converters (ADC) Applications

• Motor control sensor interface
• Industrial process monitoring
• Data acquisition systems requiring phase-sensitive measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure the external reference voltage meets the required range for the target application. Confirm pin compatibility during integration to avoid signal routing errors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous channel sampling is critical for maintaining relative phase data. The SAR architecture offers a balance between speed and power efficiency suitable for battery-operated or thermally constrained environments. Verify that the system clock frequency falls within the specified operational limits for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC122S655 series of dual-channel converters. It shares architectural similarities with other low-power SAR ADCs but is distinct in its simultaneous sampling capability and specific serial interface configuration. The NOPB suffix indicates lead-free construction compliant with RoHS standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes must match the 12-bit resolution, dual-channel simultaneous sampling requirement, and MSOP-10 package. Verify that alternative devices support the same 200 kSPS to 500 kSPS rate and industrial temperature range without altering the system's timing constraints.
