TLC251CP

The TLC251CP is a highly reliable integrated analog-to-digital converter that offers exceptional performance and versatility. With its 10-bit resolution and maximum sampling rate of 50 kilosamples per second, this ADC is suitable for a wide range of applications. Its single power supply voltage requirement of 2.7V to 5.5V makes it easy to integrate into various systems without the need for multiple power sources
