The MAX6126AASA21+T is an ultra-high-precision, ultra-low-noise series voltage reference from Analog Devices. It is designed to provide an accurate supply reference voltage, with a low-noise ripple, over a wide temperature range with exceptional temperature stability. It has an adjustable voltage range of 2.048 V to 10 V, allowing the user to fine-tune the reference voltage to a specific application. It also has a low-dropout voltage of 100 mV, ensuring a clean, stable reference voltage without disruption. The device also has a low-current operation of 10 µA with a standby current of 1 µA, which helps reduce power consumption. It is designed to perform in high-noise environments due to its low-noise ripple of only 0.5 µV peak-to-peak, making it ideal for precision applications such as high-speed data converters. The device comes in an SOIC package (8-lead) and is hermetically sealed to protect it from environmental contamination.
