Precision Micropower Shunt Voltage Reference in bare die form

Description

The LM4040C-1.2 is a high precision, two-terminal

shunt mode, bandgap voltage reference with fixed

reverse breakdown voltage of 1.225V. The device is

ideal for space-critical high reliability applications with

initial 0.5 accuracy and 100ppm/°C max temperature

coefficient. A 45μA to 12mA shunt current capability

with low dynamic impedance ensures stable reverse

breakdown voltage accuracy over a wide current range

and operating temperature. No external stabilizing

capacitors are required.

Features:

0.5 (max) output voltage tolerance at 25°C

15ppm/°C typical temperature coefficient at 25°C

Wide operating current range 45μA to 12mA

No output capacitor required

Tolerates capacitive load

Bandgap reference corrects temperature drift

Specified over military temperature range.
