ADR3512WCRMZ-R7

参考电压 1.2V 4ppm/C 0.60CMOS V Ref

Product Details

The ADR3512 is a low cost, low power, high precision CMOS voltage reference, featuring a maximum temperature coefficient TC of 4 ppm/°C C grade, −40°C to +85°C, 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 the Analog Devices, Inc., patented DigiTrim® technology.  

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

This CMOS reference is specified over the automotive temperature range of −40°C to +125°C.
