ADR821 - precision voltage reference and op amp

This page provides the datasheet information for the ADR821, a member of the ADR827 precision voltage reference and op amp family.

Datasheet Summary

Description

The ADR821/ADR827 combines a precision voltage reference and an op amp in a 10-lead mini small outline package (MSOP).

The reference and the op amp can be operated independently, offering the user a range of flexibility when arranging the combination.

Features

  • 10-lead MSOP 400 μA supply current.
  • 40°C to +125°C temperature range On-board precision resistors Reference ADR821: 2.8 V to 15 V operation ADR827: 2.7 V to 15 V operation ±0.2% initial accuracy 15 ppm/°C temperature drift maximum +5 mA/.
  • 3 mA output drive Amplifier ADR821 ±2.8 V to ±15 V operation 2.8 V to 15 V single-supply operation ADR827 ±2.7 V to ±15 V operation 2.7 V to 15 V single-supply operation Rail-to-rail input and output 500 μV offset voltage maximum 50 nA bias curre.
