GENERAL 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. Featuring a combined operating current of less than 400 μA and 15 ppm/°C temperature drift on the reference, the ADR821/ADR827 are ideally suited for applications requiring precision and low power.
