TDA9955HL/17/C1,51 Overview
Presented in package 100-LQFP.In the Tape & Reel (TR) package, you can find this data acquisition unit.The recommended working temperature is 0°C~70°C in order to maintain normal operation.The outstanding ADC, Video 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 1.75V~1.85V 3.15V~3.45V for the supply voltage.In total, 100 terminations have occurred.The 1 function here gives access to high performance for whatever application you want to run.As a result of deploying 2 channels, this unit is able to efficiently perform complex tasks.If you're looking for parts with similar specs, search "TDA9955".ADCs/DACs has 100 pins when ADCs/DACs comes to pin count.At least 1.75V can be used as a power supply for the device.There is a restriction on the supply voltage exceeding 1.85V.
