LT1031_05 Datasheet, PDF (4/12 Pages) Linear Technology – Precision 10V Reference

LT1031/LH0070
CROSS REFERENCE
The following cross reference guide may be used to select
LT1031 grades which meet or exceed output voltage,
temperature drift, load and line regulation, and output
current specifications of the AD581 reference. Parameters
such as noise, hysteresis, and long term stability will be
significantly better for all LT1031 grades compared to the
AD581.
