GENERAL DESCRIPTION
The ADR3525W, ADR3530W, ADR3533W, ADR3540W, and
ADR3550W are low cost, low power, high precision CMOS
voltage references, featuring a maximum temperature coeffi-
cient (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 the
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.
