ADC102S021CIMM

Analog To Digital Converters (ADC) Overview

The ADC102S021CIMM is a low-power, two-channel CMOS 10-bit analog-to-digital converter featuring a high-speed serial interface. Unlike conventional devices specified at a single rate, it is fully characterized across a sample rate range of 50 ksps to 200 ksps. The architecture utilizes successive-approximation register logic with an internal track-and-hold circuit. It operates on a single supply voltage ranging from +2.7V to +5.25V, consuming typical power of 1.94 mW at 3V and 6.9 mW at 5V. Key performance metrics include a typical signal-to-noise ratio (SNR) of 61.8 dB, differential non-linearity (DNL) of ±0.13 LSB, and integral non-linearity (INL) of ±0.13 LSB.

Analog To Digital Converters (ADC) Part Context

The ADC102S021CIMM belongs to the ADC102S family of 10-bit converters. It is pin-compatible with other resolutions and speeds in the series, including the 8-bit ADC082S021, 12-bit ADC122S021, and higher-speed variants like the ADC102S051 and ADC102S101. This compatibility allows for design flexibility while maintaining the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same package include the ADC082S021 (8-bit), ADC122S021 (12-bit), ADC102S051 (200-500 ksps), and ADC102S101 (500 ksps-1 Msps). These devices share identical pinouts and functionality but differ in resolution or maximum throughput specifications.
