This reference design features the industry's first zero-crossover and zero-drift amplifier (OPA388) to buffer the analog output of a digital-to-analog converter (DAC). It demonstrates the importance of the zero-crossover and zero-drift feature and how they can minimize the integral non-linearity (INL) of the system as well as make use of the full-scale range of the DAC (DAC8830).
- Precision DAC (DAC8830) provides excellent linearity, low glitch, low noise and fast setting
- Operates at 2.7-5.5 V single-supply, which is compatible with most DSP/MCU power requirements
- Zero-crossover, zero-drift op amp (OPA388) provides true precision to minimize contributions to DAC INL (<0.5 LSB)
