Overview
Micropower, High Accuracy Voltage References ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ADR3440/ADR3450 FEATURES Initial accuracy: ±0.
1% (maximum) Maximum temperature coefficient: 8 ppm/°C 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: 250 mV at 2 mA Output noise (0.
1 Hz to 10 Hz): <10 μV p-p at 1.
2 V (typical) 6-lead SOT-23 APPLICATIONS Precision data acquisition systems Industrial instrumentation Medical devices Battery-powered devices GENERAL DESCRIPTION The ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ ADR3440/ADR3450 are low cost, low power, high precision CMOS voltage references, featuring ±0.
1% initial accuracy, low operating current, and low output noise in a small SOT-23 package.
For high accuracy, output voltage and temperature coefficient are trimmed digitally during final assembly using Analog Devices, Inc.
, proprietary DigiTrim® technology.
Stability and system reliability are further improved by the low output voltage hysteresis of the device and low long-term output voltage drift.
Furthermore, the low operating current of the device (100 μA maximum) facilitates usage in low power devices, and its low output noise helps maintain signal integrity in critical signal processing systems.
These CMOS are available in a wide range of output voltages, all of which are specified over the industrial temperature range of −40°C to +125°C.
