Description

The LM285/285B-1.2V (1.235V output) and LM285/385- 2.5V (2.5V output) are bipolar, two-terminal, bandgap voltage references that offer precision performance without premium price. These devices do not require thin-film resistors, greatly lowering manufacturing complexity and cost.

A 30ppm/°C output temperature coefficient and a 15A to 20mA operating current range make these voltage references especially attractive for multimeter, data acquisition and telecommunications applications.
