50 V, 130 kHz, 32.5 μA, Robust,

Over-The-Top Precision Op Amp

ADA4097-1

Data Sheet

FEATURES

GENERAL DESCRIPTION

Ultrawide common-mode input range: −V_S− 0.1 V to −V_S+ 70 V

Wide power supply voltage range: +3 V to +50 V (to 25 V for PSRR)

Low power supply current: 32.5 μA (typical)

Low input offset voltage: 60 μV maximum

Low input offset voltage drift: 1 μVꢀ/C maximum (B grade)

Low input voltage noise

The ADA4097-1 is a robust, precision, rail-to-rail input and output

operational amplifier (op amp) with inputs that operate from −V_S

to +V_Sand beyond, which is referred to in this data sheet as Over-

The-Top™. The device features offset voltages of <60 μV, input bias

currents (I_B) of <0.3 nA, and can operate on single or split supplies

that range from 3 V to 50 V. The ADA4097-1 draws 32.5 μA of

supply current.

6 Hz typical 1ꢀf noise corner

1000 nV p-p typical at 0.1 Hz to 10 Hz

The ADA4097-1 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 common-mode input

range extends from rail-to-rail and beyond, up to 70 V > –V_S,

independent of the +V_Ssupply.

GBP: 130 kHz typical for f_TEST= 250 Hz

Slew rate: 0.1 Vꢀμs typical at ΔV_OUT= 4 V

Low power supply current shutdown: 20 μA maximum

Low input offset current: 300 pA maximum

Large signal voltage gain: 120 dB minimum for ΔV_OUT= 4 V

CMRR: 120 dB minimum at V_CM= −0.1 V to +70 V

PSRR: 123 dB minimum at V_SY= +3 V to 25 V

Input overdrive tolerant with no phase reversal

2 kV HBM and 1.25 kV FICDM

The ADA4097-1 is unity-gain stable and can drive loads requiring

up to 20 mA. The device can also drive capacitive loads as large as

200 pF. The amplifier is available with low power shutdown.

Wide temperature range: −55/C to +150/C (H grade)

6-lead TSOT package

The ADA4097-1 is available in a standard, 6-lead, thin small

outline transistor (TSOT) package.
