General Description

The AD581 is a 3-pin, temperature compensated, monolithic, band gap voltage reference that provides a precise 10.00 V output from an unregulated input level ranging from 12 V to 30 V.

Laser wafer trimming (LWT) is used to trim both the initial error at +25°C as well as the temperature coefficient, resulting in high precision performance previously available only in expensive hybrids or oven regulated modules.

The 5 mV initial error tolerance and 5 ppm/°C guaranteed temperature coefficient of the AD581L is available in a monolithic voltage reference.

Key Features

  • Laser trimmed to high accuracy 10.000 V ±5 mV (L and U models) Trimmed temperature coefficient 5 ppm/°C maximum, 0°C to 70°C (L model) 10 ppm/°C maximum,.
  • 55°C to +125°C (U model) Excellent long-term stability 25 ppm/1000 hrs (noncumulative).
  • 10 V reference capability Low quiescent current: 1.0 mA maximum 10 mA current output capability 3-pin TO-5 package MIL-STD-883 compliant versions available.
