LT1236

Precision Reference

DESCRIPTIO

EATURE

The LT^®1236 is a precision reference that combines ultra-

low drift and noise with excellent long-term stability and

high output accuracy. The reference output will both

source and sink up to 10mA and is almost totally immune

to input voltage variations. Two voltages are available: 5V

and10V. The10Vversioncanbeusedasashuntregulator

(two-terminal zener) with the same precision characteris-

tics as the three-terminal connection. Special care has

been taken to minimize thermal regulation effects and

temperature induced hysteresis.

■

Ultra-Low Drift: 5ppm/°C Max

Trimmed to High Accuracy: 0.05% Max

Industrial Temperature Range SO Package

Operates in Series or Shunt Mode

Pin Compatible with AD586, AD587

Output Sinks and Sources in Series Mode

Very Low Noise < 1ppm _P-P(0.1Hz to 10Hz)

100% Noise Tested

> 100dB Ripple Rejection

Minimum Input/Output Differential of 1V

The LT1236 combines both superior accuracy and tem-

power,on-chipheaters.TheLT1236referencesarebased

on a buried zener diode structure which eliminates noise

and stability problems with surface breakdown devices.

Further, a subsurface zener exhibits better temperature

drift and time stability than even the best band-gap

references.
