Hot-selling and scarce ADUC7025BSTZ62 Precision Analog Microcontroller 12-bit Analog I/O LQFP64 spot stock

Product Descriptions

The ADuC7019/7020/7021/7022/7024/7025/7026/7027 are fullyintegrated, 1 MSPS, 12-bit data acquisition systems incorporating high performance multichannel ADCs, 16-bit/32-bit MCUsand Flash/EE memory on a single chip.

The ADC consists of up to 12 single-ended inputs . Anadditional four inputs are available but are multiplexed

with the four DAC output pins . The four DAC outputs areonly available on certain models (ADuC7020, and ADuC7026).However, in many cases where the DAC outputs are not present,these pins can still be used as additional ADC inputs, giving amaximum of 16 ADC input channels . The ADC can operate insingle-ended or differential input modes . The ADC inputvoltage is 0 to VREF. Low-drift bandgap reference, temperaturesensor, and voltage comparator complete the ADC peripheralset .

Depending on the part model, up to four buffered voltageoutput DACs are available on-chip. The DAC output range isprogrammable to one of three voltage ranges .
