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: −V_S− 0.1 V to −V_S+ 70 V

► Wide power supply voltage range: (V_SY): +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 (e_n)

► High speed

► GBP: 8 MHz typical

► Slew rate: 5.5 V/µs typical at ΔV_OUT= 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 −V_Sto +V_Sand beyond, which is referred to

™

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

voltages of <40 µV, input bias currents (I_B) 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 > –V_S,

independent of the +V_Ssupply.

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
