LM169/LM369 Precision Voltage Reference

General Description

Features

Low Tempco

3 ppm/ C (max)

5 mV (max)

The LM169/LM369 are precision monolithic temperature-

compensated voltage references. They are based on a bur-

ied zener reference as pioneered in the LM199 references,

but do not require any heater, as they rely on special tem-

perature-compensation techniques (Patent Pending). The

LM169 makes use of thin-film technology enhanced by the

discrete laser trimming of resistors to achieve excellent

4 ppm/V (max)

Excellent initial accuracy

Excellent line regulation

20 ppm/100 mW (max)

Excellent output impedance

0.8X (max)

Excellent thermal regulation

Low noise

Easy to filter output noise

Temperature coefficient (Tempco) of V

max). The trim scheme is such that individual resistors are

cut open rather than being trimmed (partially cut), to avoid

resistor drift caused by electromigration in the trimmed area.

The LM169 also provides excellent stability vs. changes in

input voltage and output current (both sourcing and sinking).

The devices have a 10.000V output and will operate in ei-

ther series or shunt mode; the output is short-circuit-proof to

ground. A trim pin is available which permits fine-trimming of

put noise by adding a small capacitor (0.05 to 0.5 mF).
