Low quiescent current: 100 µA (maximum)
Figure 1. 8-Lead MSOP (RM-8 Suffix)
Low dropout voltage: 1.15 V at 2 mA Output voltage noise (0.1 Hz to 10 Hz): 8 µV p-p (typical) Qualified for automotive applications APPLICATIONS Automotive battery monitors Portable instrumentation Process transmitters Remote sensors Medical instrumentation GENERAL DESCRIPTION
The ADR3512 is a low cost, low power, high precision CMOS The low output voltage hysteresis and low long-term output voltage voltage reference, featuring a maximum temperature coefficient drift improve lifetime system accuracy. (TC) of 4 ppm/°C (C grade, −40°C to +85°C), low operating This CMOS reference is specified over the automotive temperature current, and low output noise in an 8-lead MSOP package. For range of −40°C to +125°C. high accuracy, the output voltage and temperature coefficient are trimmed digitally during final assembly using the Analog
