Overview
Data Sheet Micropower, Low Noise Precision Voltage References with Shutdown ADR391/ADR392/ADR395 FEATURES Compact 5-lead TSOT package Low temperature coefficient B grade: 9 ppm/°C A grade: 25 ppm/°C Initial accuracy B grade: ±4 mV maximum (ADR391) A grade: ±6 mV maximum Ultralow output noise: 5 μV p-p (0.
1 Hz to 10 Hz) Low dropout: 300 mV Low supply current 3 μA maximum in shutdown 140 μA maximum in operation No external capacitor required Output current: 5 mA Automotive grade available Wide temperature range: −40°C to +125°C APPLICATIONS Battery-powered instrumentation Portable medical instrumentation Data acquisition systems Industrial process controls Automotive GENERAL DESCRIPTION The ADR391/ADR392/ADR395 are precision 2.
5 V, 4.
096 V, and 5 V band gap voltage references, respectively, featuring low power and high precision in a tiny footprint.
Using patented temperature drift curvature correction techniques from Analog Devices, Inc.
, the ADR39x references achieve a low 9 ppm/°C of temperature drift in the TSOT package.
