ADC121S051CISDX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC121S051CISDX/NOPB is a single-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates with a sample rate range of 200 ksps to 500 ksps and supports a supply voltage from 2.7V to 5.25V. The device utilizes a successive-approximation register architecture with an internal track-and-hold circuit. It features a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Typical power consumption is 1.7 mW at 3.6V and 8.7 mW at 5.25V. The component is available in 6-lead WSON and SOT-23 packages.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix CISDX against the manufacturer's official documentation to confirm the specific package type (WSON or SOT-23) and tape-and-reel configuration. Ensure that the NOPB designation indicates lead-free and RoHS compliance as per the current product specification sheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a low-power, single-channel conversion solution within the 200–500 ksps range. Consider the 6-lead WSON or SOT-23 package constraints regarding thermal resistance and board space. Ensure the system clock frequency aligns with the specified 4 MHz to 10 MHz range for optimal electrical performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC121S051 family of single-channel, 12-bit A/D converters. It is pin-compatible with other devices in the series such as the ADC121S021 and ADC121S101, which offer different specified sample rate ranges but maintain functional compatibility.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC121S021 for lower speeds (50–200 ksps) and the ADC121S101 for higher speeds (500 ksps to 1 Msps). Other resolutions like the ADC101S051 or ADC081S051 are also functionally compatible.
