ADUC7023BCPZ62I-R7

ADUC7023 is a precision analogue microcontroller, 12-bit analogue I/O, ARM7TDMI MCU with enhanced IRQ handler. It is a fully integrated, 1MSPS, 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 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 modes. The ADC input voltage 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 two 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 optical networking, industrial control and automation systems, smart sensors, precision instrumentation, base station systems etc.
