CS53L21-CNZR Overview
Presented in package 32-VFQFN Exposed Pad.In the Tape & Reel (TR) package, you can find this data acquisition unit.The recommended working temperature is -10°C~70°C in order to maintain normal operation.The outstanding ADC, Audio is what you paid.ADCs/DACs is best to mount this part through Surface Mount in order to save more space.For this unit, you should redo the circuit if your meter reads something other than 1.65V~1.89V 2.37V~2.63V for the supply voltage.In total, 32 terminations have occurred.The 1 function here gives access to high performance for whatever application you want to run.As a result of deploying 3 channels, this unit is able to efficiently perform complex tasks.If you're looking for parts with similar specs, search "CS53L21".This data acquisition unit should be powered by 1.8V voltage.ADCs/DACs has 32 pins when ADCs/DACs comes to pin count.An integrated data acquisition device with a 24-bit resolution is used in this application.Several cases of use could be made more feasible by using the Surface Mount technique.Using 2.5V, this device can be powered.In order to facilitate high-level analog source acquisition, 2 analog IN channels have been implemented.Analog-to-digital converters/Digital-to-analog converters consists of 2 A/D converters.The 6 analog inputs ensured fast and accurate data acquisition with this part.
