Description

TheADR3525W, ADR3530W,ADR3533W,ADR3540W, andADR3550Ware low cost, low power, high precision CMOS voltage references, featuring a maximum temperature coefficient (TC) of 5 ppm/°C (B grade), 8 ppm/°C (A grade), 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 Analog Devices, Inc., patented DigiTrim®technology.The low output voltage hysteresis and low long-term output voltage drift improve lifetime system accuracy.These CMOS references are available in five output voltages, all of which are specified over the automotive temperature range of −40°C to +125°C.APPLICATIONSAuto battery monitorsPortable instrumentationProcess transmittersRemote sensorsMedical Instrumentation
