Key Features
- Precision 5 V output with ±14 mV maximum tolerance (4.993 V to 5.007 V) for accurate ADC and DAC references
- Three-terminal series reference architecture enabling simple drop-in replacement for MAX673 in existing designs
- Low temperature coefficient in 8-pin PDIP package suitable for instrumentation and calibration equipment
Applications
MAX675CPA+ serves as a precision voltage reference in data acquisition systems, digital multimeters, and precision signal conditioning circuits requiring a stable 5 V reference rail. Its tight 4.993 V to 5.007 V output window ensures less than 0.14% initial accuracy, making it appropriate for calibrating 12-bit and 14-bit ADCs without additional trimming. The 8-pin PDIP format allows easy prototyping and replacement of legacy MAX673 designs in industrial instruments.

Frequently Asked Questions
What is the output voltage accuracy of MAX675CPA+ and how does it affect 12-bit ADC calibration?
MAX675CPA+ guarantees an output voltage between 4.993 V and 5.007 V, representing ±14 mV or ±0.14% initial accuracy. For a 12-bit ADC with a 5 V full-scale range, the 4096 LSB count corresponds to approximately 1.22 mV per step, so the ±14 mV reference error introduces a worst-case full-scale error of about 11 LSBs without external calibration.
Can MAX675CPA+ directly replace MAX673 in existing precision reference circuits?
Yes, MAX675CPA+ is a pin-compatible drop-in replacement for MAX673, sharing the same 8-pin PDIP-300 mil footprint and three-terminal series reference architecture. Design engineers upgrading legacy boards benefit from improved accuracy and availability without requiring PCB layout changes, though the datasheet should be checked for any differences in quiescent current or minimum input-to-output headroom voltage.
What minimum input voltage headroom does MAX675CPA+ require above the 5 V output?
As a series three-terminal reference, MAX675CPA+ requires a minimum input-to-output dropout headroom, typically around 1 V to 2 V above the 5.007 V maximum output, meaning the supply must be at least 6 V to 7 V for stable regulation. This headroom requirement should be budgeted in battery or regulated supply designs to prevent output dropout at end-of-life supply voltage.
