LT1021

Precision Reference

DESCRIPTIO

FEATURES

The LT^®1021 is a precision reference with ultralow drift

and noise, extremely good long term stability and almost

total immunity to input voltage variations. The reference

output will both source and sink up to 10mA. Three

voltages are available: 5V, 7V and 10V. The 7V and 10V

unitscanbeusedasshuntregulators(two-terminalzeners)

with the same precision characteristics as the three-

terminal connection. Special care has been taken to mini-

mize thermal regulation effects and temperature

induced hysteresis.

■

Ultralow Drift: 5ppm/°C Max Slope

■

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

100% Noise Tested

■

Pin Compatible with Most Bandgap Reference

Applications, Including Ref 01, Ref 02, LM368,

MC1400 and MC1404 with Greatly Improved

Stability, Noise and Drift

■

Trimmed Output Voltage

Operates in Series or Shunt Mode

Output Sinks and Sources in Series Mode

>100dB Ripple Rejection

TheLT1021referencesarebasedonaburiedzenerdiode

structure that eliminates noise and stability problems

associated with surface breakdown devices. Further, a

subsurface zener exhibits better temperature drift and

time stability than even the best bandgap references.

Minimum Input/Output Differential of 1V

Available in 5-Lead Can, N8 and S8 Packages

APPLICATIO S

Unique circuit design makes the LT1021 the first IC

reference to offer ultralow drift without the use of high

power on-chip heaters.

A/D and D/A Converters

■

Precision Regulators

■

Digital Voltmeters

Inertial Navigation Systems

The LT1021-7 uses no resistive divider to set output

voltage,andthereforeexhibitsthebestlongtermstability

and temperature hysteresis. The LT1021-5 and LT1021-

10areintendedforsystemsrequiringaprecise5Vor10V

reference with an initial tolerance as low as ±0.05%.
