The MAX6070BAUT12/V+T is a low-noise, high-precision series voltage reference in a 6-pin SOT-23 package. It provides a fixed output of 1.25V with ±0.08% initial accuracy and a maximum temperature drift of 8ppm/°C (B grade). The device operates on a supply voltage from 2.7V to 5.5V, consuming 130µA to 260µA of quiescent current. It supports up to 10mA load current sourcing or sinking, features an enable pin, and includes a filter option for noise reduction.
Verify the specific suffix /V+T indicates automotive qualification and tape-and-reel packaging. Confirm the B grade designation corresponds to the required ±0.08% accuracy and 8ppm/°C drift specifications. Ensure the source documentation explicitly lists this part number as available or discontinued before procurement planning.
Select this component when a 1.25V reference is required with tight tolerance and low drift. The B grade offers higher accuracy than D grade but lower than A grade. Consider the MAX6071 if the internal filter is not needed for faster settling times. Verify that the 2.7V minimum input voltage meets system requirements.
This part belongs to the MAX6070/MAX6071 family of low-noise, high-precision series voltage references. The MAX6070 variant includes a filter pin for noise reduction, while the MAX6071 does not. Both are designed for high-accuracy applications in small packages.
MAX6070AAUT12/V+T offers tighter accuracy (±0.04%) and drift (6ppm/°C) but may have different availability.
Connecting a capacitor to the FILTER pin reduces high-frequency noise, improving performance for wideband applications.
The B grade has a maximum temperature drift of 8ppm/°C and ±0.08% accuracy, whereas the A grade offers 6ppm/°C and ±0.04%.
