How does the 1.2mA active current benefit battery-powered DAQ devices?
Active current is the power the IC uses when generating analog outputs. At 1.2mA, the AD5423BCPZ-RL7 uses 35% less power than typical 16-bit DACs (1.8?C2.0mA). For a 1000mAh industrial sensor battery, this extends runtime from 9 months to 14+ months??reducing replacements in hard-to-reach locations like factory ceilings or wind turbine nacelles, lowering operational costs.
What value does on-chip linearization add to DAC DAQ designs?
On-chip linearization compensates for voltage drift and component variations, ensuring the DAC??s output stays within ??1LSB accuracy across temperature and voltage changes. This eliminates the need for external linearization chips, cutting BOM costs by 15% and PCB space by 10%. For calibrated systems (e.g., smart grid sensors), it also reduces field calibration frequency??saving time and resources for end users.
Can this IC operate in harsh automotive or industrial environments?
Yes??its -40??C to 105??C operating range and AEC-Q100 compliance meet automotive/industrial standards. It withstands extreme heat (105??C in automotive engine bays) and cold (-40??C in winter industrial sites) without losing precision. Its over-temperature protection also shuts down safely if temperatures exceed limits, preventing damage to the IC and surrounding components??unlike consumer-grade DACs that fail catastrophically.
Which ADI tools support programming and testing the AD5423BCPZ-RL7?
ADI??s EVAL-AD5423 Kit includes a pre-configured AD5423BCPZ-RL7, analog output probes, and a USB-to-SPI bridge for PC connectivity. The free DAC Studio Software lets engineers adjust output ranges, run linearity tests, and save calibration settings??no custom code required.
