Precision Micropower Shunt Voltage Reference in bare die form

描述 Description

The LM4040D-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 1 accuracy and 150ppm/°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:

1 (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.
