Product Details
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).
APPLICATIONS
- Industrial sensor conditioning
- Supply current sensing
- Battery and power supply monitoring
