ADUC845BSZ62-5

ADUC845 is a micro converter® multichannel ADC. It include additional analog inputs for applications requiring more ADC channels. It is a complete smart transducer front ends. It integrates high resolution Σ-Δ ADC with flexible, upto 10-channel, input multiplexing, a fast 8-bit MCU, and program and data Flash/EE memory on a single chip. The devices operate from a 32kHz crystal with an on-chip PLL generating a high frequency clock of 12.58MHz. It is widely used in application such as multichannel sensor monitoring, industrial/environmental instrumentation, weigh scales, pressure sensors, temperature monitoring, portable instrumentation, battery-powered systems, data logging, precision system monitoring etc.
