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.
