The operating voltage range of 1.5V to 5.5V and supply current of 0.29uA typical with stable over temperature and input voltage change makes it ideal for micropower oxygen sensors, gas sensors and remote sensor applications. In addition to the ultralow power and low operating voltage, rail-to-rail input and output, input offset voltage of 1mV maximum with 0.65uV/ºC drift, input bias current of 10pA maximum and ability to drive 470pF loads, make the NJU77001/NJU77001 ideal when requiring excellent performance in battery powered applications. The NJU77000 is available in the 5-pin SC-88A package. NJU77001 is available in the 5-pin SOT-23 and SC-88A package. NJU77000 and NJU77001 have difference pin function (see pin configuration). The NJU7700xA have the higher performance and offer guaranteed specifications over the extended temperature range from -40ºC to +105ºC.

(2) For supply voltage less than +7V, the absolute maximum rating is equal to the supply voltage. (3) Power dissipation is the power that can be consumed by the IC at Ta=25ºC, and is the typical measured value based on JEDEC condition. When using the IC over Ta=25ºC subtract the value [mW/ºC]=PD/(Tstg(MAX)-25) per temperature. 2-layer: EIA/JEDEC STANDARD Test board (76.2x114.3x 1.6mm, 2layers, FR-4) mounting ■ RECOMMENDED OPERATING CONDITIONS (Ta=25ºC) PARAMETER Supply Voltage Ver.00 SYMBOL + - V -V CONDITION MIN. 1.5 TYP.
