SL121S021 is a 12-bit ADC (Analog-to-Digital Converter) chip with the basic characteristics of high resolution, low power consumption, small size and unipolarity. The performance parameters of SL121S021 cover a wide sampling range of 50KSPS to 200KSPS, and are not only valid at a specific sampling rate. The converter is based on a successive approximation register architecture with an internal sample-and-hold circuit. SL121S021 is powered by a single power supply of 3.3 V to 5.25 V and has a power saving mode. The SL121S021 is available in a 6-pin SOT-23 package and operates over the -40°C to 85°C temperature range.

Ultra-low power consumption 3.3V-5.25V operating voltage 250KSPS 10/12-bit analog-to-digital converter (ADC)
The SL11661/SL11663/SL11665 series are analog-to-digital converters (ADC) with basic features including 8/10/12-bit resolution, ultra-low power consumption, small size, unipolar, and single-ended input. They offer convenient power/serial clock speed management. The conversion rate is determined by the serial clock, and conversion time can be reduced by increasing the serial clock speed. With the ability to automatically shut down, the automatic power-down after conversion helps reduce average power consumption.
