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 TC of 5ppm/°C B grade, low operating current, and low output noise in an 8 lead MSOP package. For high accuracy, 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 are available in five output voltages, all of which are specified over the automotive temperature range of −40°C to +125°C.
