GENERAL DESCRIPTION

The ADA4099-1 and ADA4099-2 are single/dual robust, precision,

rail-to-rail input/output operational amplifiers (op amps) with inputs

that operate from −VS to +VS and beyond, which is referred to

in this data sheet as Over-The-Top™. The devices feature offset

voltages of <40 µV, input bias currents (IB) of <10 nA, and can

operate on single or split supplies that range from 3.15 V to 50 V.

The ADA4099-1 and ADA4099-2 draws 1.5 mA of quiescent current

per channel.

The ADA4099-1 and ADA4099-2 Over-The-Top input stages have

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 ADA4099-1 and ADA4099-2 are 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 amplifiers are

available with low power shutdown.

The ADA4099-1 is available in a standard, 6-lead, thin small outline

transistor (TSOT) package. The ADA4099-2 is available in an 8-

lead, standard small outline package (SOIC_N), 8-lead, mini small

outline package (MSOP), and a 10-lead, lead frame chip scale

package (LFCSP).
