Data Sheet ADA4097-1/ADA4097-2 50 V, 130 kHz, 32.5 A per Channel, Robust, Over-The-Top, Precision Op Amps FEATURES Battery and power supply monitoring Front-end amplifiers in abusive environments Ultrawide common-mode input range: V 0.1 V to V + 70 V S S 4 mA to 20 mA transmitters Wide power supply voltage range: +3 V to +50 V (to 25 V for PSRR) GENERAL DESCRIPTION Low power supply current: 32.5 A (typical) The ADA4097-1/ADA4097-2 are single and dual robust, precision, Low input offset voltage: 60 V maximum rail-to-rail input and output operational amplifiers (op amps) with Low input offset voltage drift: 1 V/C maximum (B grade) inputs that operate from V to +V and beyond, which are referred S S Low input voltage noise to in this data sheet as Over-The-Top . The devices feature offset 6 Hz typical 1/f noise corner voltages of <60 V, input bias currents (I ) of <0.3 nA, and can B 1000 nV p-p typical at 0.1 Hz to 10 Hz operate on single or split supplies that range from 3 V to 50 V. The ADA4097-1/ADA4097-2 draw 32.5 A of supply current per GBP: 130 kHz typical for f = 250 Hz TEST channel. Slew rate: 0.1 V/s typical at V = 4 V OUT The ADA4097-1/ADA4097-2 Over-The-Top input stages have ro- Low power supply current shutdown: 20 A maximum bust input protection features for abusive environments. The inputs Low input offset current: 300 pA maximum can tolerate up to 80 V of differential voltage without damage or Large signal voltage gain: 120 dB minimum for V = 3.5 V OUT degradation to dc accuracy. The operating common-mode input CMRR: 120 dB minimum at V = 0.1 V to +70 V CM range extends from rail-to-rail and beyond, up to 70 V > V , S PSRR: 123 dB minimum at V = +3 V to 25 V SY independent of the +V supply. S Input overdrive tolerant with no phase reversal The ADA4097-1/ADA4097-2 are unity-gain stable and can drive 2 kV HBM and 1.25 kV FICDM loads requiring up to 20 mA per channel. The devices can also Wide temperature range: 55C to +150C (H grade) drive capacitive loads as large as 200 pF. The amplifiers are Shutdown feature available for single 6-lead TSOT and dual available with low power shutdown. 10-lead LFCSP packages The ADA4097-1 is available in a standard, 6-lead thin small out- line transistor (TSOT) package. The ADA4097-2 is available in APPLICATIONS an 8-lead standard small outline (SOIC N) package, 8-lead mini Industrial sensor conditioning small outline package (MSOP), and 10-lead lead-frame chip-scale Supply current sensing package (LFCSP).
