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.
