ADUC7126BSTZ126

ADUC7126 is a fully integrated, 1MSPS, 12bit data acquisition system incorporating high performance multichannel ADCs, 16bit/32-bit MCUs, and flash/EE memory on a single chip. The ADC consists of upto 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 mode. The ADC input voltage range is 0V to VREF. A low drift band gap reference, temperature sensor, and voltage comparator complete the ADC peripheral set. The DAC output range is programmable to one of three voltage ranges. The DAC outputs have an enhanced feature of being able to retain their output voltage during a watchdog or software reset sequence. It is used in application such as industrial control and automation systems, smart sensors, precision instrumentation, base station systems, optical networking, patient monitoring etc.
