ADR3525WBRMZ-R7

微功耗，高精度 Micropower, High Accuracy

Product Details

The ADR3525W, ADR3530W, ADR3533W, ADR3540W, and ADR3550W are low cost, low power, high precision CMOS voltage references, featuring a maximum temperature coefficient TC of 5 ppm/°C B grade, 8 ppm/°C A grade, low operating current, and low output noise in an 8-lead MSOP package. For high accuracy, the output voltage and temperature coefficient are trimmed digitally during final assembly using Analog Devices, Inc., patented DigiTrim® technology.

The low output voltage hysteresis and low long-term output voltage drift improve lifetime system accuracy.

These CMOS references are available in five output voltages, all of which are specified over the automotive temperature range of −40°C to +125°C.
