GENERAL DESCRIPTION
The ADA4099-2BCHIPS is a robust, precision, rail-to-rail input and
output dual-channel operational amplifier with inputs that operate
from −VS to +VS and beyond, which is referred to in this data sheet
as Over-The-Top™. The device features an offset voltage of ±12 μV,
an input bias current (IB) of ±4 nA, and can operate on supplies that
range from 3.15 V to 50 V. The ADA4099-2BCHIPS draws 1.65 mA
of supply current per channel.
The ADA4099-2BCHIPS Over-The-Top input stage has robust input
protection features for abusive environments. The inputs can tolerate
up to 80 V of differential voltage without damage or degradation
to dc accuracy. The operating input common-mode range extends
from rail-to-rail and beyond, up to 70 V > –VS, independent of the
+VS supply.
The ADA4099-2BCHIPS is unity-gain stable and can drive loads
requiring up to 20 mA per channel. The device can also drive
capacitive loads as large as 100 pF. The amplifier is available with
low power shutdown per channel.
The ADA4099-2BCHIPS is specified at +25°C but is functional
over the extended industrial temperature range (−40°C to +125°C).
Additional application and technical information can be found in the
ADA4099-2 data sheet.
