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 requir-

ing precision and low power.

Available with the reference at 1.25 V and at 2.5 V, the

ADR821/ADR827 also come in two grades. The reference on

the A grade offers 30 ppm/°C temperature drift performance

and 0.4% initial accuracy. The B grade provides a tighter

temperature drift performance of 15 ppm/°C and only 0.2%

initial accuracy. All versions operate from −40°C to +125°C.
