LT1494/LT1495/LT1496 1.5m A Max, Single, Dual and Quad Over-The-Top Precision Rail-to-Rail Input and Output Op Amps FEATURES DESCRIPTIO n Low Supply Current: 1.5m A Max The LT 1494/LT1495/LT1496 are the lowest power n (I 1.5m A) op amps with precision specifications. The Rail-to-Rail Input and Output S n extremely low supply current is combined with excellent Low Offset Voltage: 375m V Max n amplifier specifications: input offset voltage is 375m V Operating Temperature Range: 40 C to 125 C TM + n maximum with a typical drift of only 0.4m V/ C, input offset Over-The-Top Inputs Operate Above V current is 100pA maximum. A minimum open-loop gain n Wide Supply Range: 2.2V to 36V (A ) of 100V/mV ensures that gain errors are small. The n VOL Single Supply Input Range: 0.3V to 36V device characteristics change little over the supply range n Low Input Bias Current: 250pA of 2.2V to 15V. Supply rejection is 90dB and the common n Low Input Offset Current: 20pA mode rejection ratio is 90dB. Operation is specified for 3V, n High A : 100V/mV Minimum Driving 100kW Load VOL 5V and 15V supplies. Reverse battery protection n Output Sources and Sinks 500m A Load Current (18V min) and inputs that operate above the positive n Reverse Battery Protected to 18V supply make the LT1494/LT1495/LT1496 easy to use in harsh environments. U APPLICATIO S The low bias currents and offset current of the amplifier permit the use of megohm level source resistors without n Battery- or Solar-Powered Systems introducing significant errors. Voltage noise at 4m V is P-P n Portable Instrumentation remarkably low considering the low supply current. n Remote Sensor Amplifier The LT1494 is available in the 8-Pin MSOP, PDIP and SO n Micropower Filter packages.The LT1495 is available in plastic 8-Pin PDIP and SO packages with the standard dual op amp pinout. , LTC and LT are registered trademarks of Linear Technology Corporation.
