DESCRIPTIO  
EATURE

F
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  
units canbeusedas shuntregulators (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.  
■
Pin Compatible with Most Bandgap Reference  
Applications, Including Ref 01, Ref 02, LM368,  
MC1400 and MC1404 with Greatly Improved  
Stability, Noise and Drift  
Ultralow Drift: 5ppm/°C Max Slope  
Trimmed Output Voltage  
Operates in Series or Shunt Mode  
Output Sinks and Sources in Series Mode  
Very Low Noise: <1ppm P-P (0.1Hz to 10Hz)  
>100dB Ripple Rejection  
Minimum Input/Output Differential of 1V  
100% Noise Tested

TheLT1021references arebasedonaburiedzenerdiode  
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.

Unique circuit design makes the LT1021 the first IC  
reference to offer ultralow drift without the use of high  
power on-chip heaters.

The LT1021-7 uses no resistive divider to set output  
voltage,andthereforeexhibits thebestlongtermstability  
and temperature hysteresis. The LT1021-5 and LT1021-

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