Hot-selling and scarce ADUC7023BCPZ62I Precision Analog Microcontroller IC LFCSP32 spot stock

Product Descriptions

The ADuC7023 is a fully integrated, 1 MSPS, 12-bit data acquisition system, incorporating high performance multichannel ADCs,16-bit/32-bit MCUs, and Flash/EE memory on a single chip. 

The ADC consists of up to 12 single-ended inputs.An additional four inputs are available but are multiplexed with the four DAC output pins.The ADC can operate in single-ended or differential input modes.The ADC input voltage is 0 V to V_REF.A low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set.
