ADC101S021CISDX

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADC101S021CISDX is a single-channel, 10-bit successive-approximation register (SAR) analog-to-digital converter. It operates with a single supply voltage ranging from +2.7V to +5.25V and supports sample rates between 50 ksps and 200 ksps. The device features a high-speed serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Typical performance metrics include a signal-to-noise ratio of 61.6 dB, differential non-linearity of +0.16/-0.09 LSB, and integral non-linearity of +0.14/-0.13 LSB. Power consumption is 2.34 mW at 3.6V and 8.9 mW at 5.25V in normal mode, reducing to 2.6 µW in shutdown mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package suffix 'CISDX' corresponds to the 6-lead WSON configuration with an exposed ground pad as indicated in the datasheet pin descriptions. Ensure the ordering code matches the specific tape and reel or cut tape requirements for automated assembly processes. Confirm that the component meets RoHS3 compliance standards as stated in the manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel conversion is required with 10-bit resolution and throughput up to 200 ksps. It is suitable for applications where interface compatibility with standard microprocessor serial ports is necessary. Consider the ADC121S021 if higher resolution is needed, or the ADC081S021 if lower power consumption at reduced accuracy is acceptable, as these are pin-compatible alternatives within the same family.

Analog To Digital Converters (ADC) Part Context

The ADC101S021 belongs to a family of single-channel A/D converters that includes 8-bit, 10-bit, and 12-bit variants. These devices share identical pinouts and functional compatibility, allowing for design flexibility across different resolution requirements. The ADC101S021 specifically targets applications balancing precision and speed within the 50-200 ksps range.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC121S021 (12-bit), ADC081S021 (8-bit), ADC101S051 (12-bit/500ksps), and ADC101S101 (10-bit/1Msps). All listed devices maintain function and pin compatibility, enabling direct substitution based on resolution or speed requirements.
