Overview
Data Sheet ADR3512 Micropower, High Accuracy Voltage Reference FEATURES ► Maximum temperature coefficient ► 4 ppm/°C (C grade, −40°C to +85°C) ► Low long-term drift (LTD): 30 ppm (initial 1 khr typical) ► Initial output voltage error: ±0.
1% (maximum) ► Operating temperature range: −40°C to +125°C ► Output current: +10 mA source/−3 mA sink ► Low quiescent current: 100 µA (maximum) ► 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 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.
1 PIN CONFIGURATION Figure 1.
8-Lead MSOP (RM-8 Suffix) 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.
