Data Sheet  
ADA4099-1/ADA4099-2  
50 V, 8 MHz, 1.5 mA per Channel, Robust, Over-The-Top, Precision Op Amps  
FEATURES  
GENERAL DESCRIPTION  
Ultrawide common-mode range: −VS − 0.1 V to −VS + 70 V  
Wide power supply voltage range: (VSY): +3.15 V to +50 V (±25  
V for PSRR)  
Low supply current: 1.5 mA per channel (typical)  
Low input offset voltage: ±40 µV maximum  
Low input offset voltage drift: ±0.4 μV/°C maximum  
Low voltage noise:  
1/f noise corner: 6 Hz typical  
150 nV p-p typical at 0.1 Hz to 10 Hz  
7 nV/√Hz typical at 100 Hz (en)  
High speed  
GBP: 8 MHz typical  
Slew rate: 5.5 V/µs typical at ΔVOUT = 25 V  
Low power shutdown: 20 µA maximum  
Low input bias current: ±10 nA maximum  
Large signal voltage gain: 120 dB minimum  
CMRR: 118 dB, minimum  
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).  
PSRR: 123 dB, minimum  
Input overdrive tolerant with no phase reversal  
±2 kV HBM and ±1.25 kV FICDM  
Wide temperature range: −55°C to +150°C (H grade)  
APPLICATIONS  
Industrial sensor conditioning  
Supply current sensing  
Battery and power supply monitoring  
Front-end amplifiers in abusive environments  
4 mA to 20 mA transmitters  
TYPICAL APPLICATION CIRCUIT

TSOT)
