PMICs with voltage references provide stable and accurate reference voltages used as a precise voltage standard for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), voltage regulators, and other analog circuits. Voltage references ensure consistent performance and accuracy in electronic systems by minimizing variations caused by temperature, load, and supply voltage fluctuations. They are essential components in precision instrumentation, sensor interfaces, and data acquisition systems where accurate voltage references are critical for reliable operation and measurement.
