LT1783 1.25MHz, Over-The-Top Micropower, Rail-to-Rail Input and Output Op Amp in SOT-23 FEATURES DESCRIPTION + n Operates with Inputs Above V The LT 1783 is a 1.25MHz op amp available in the small n Rail-to-Rail Input and Output SOT-23 package that operates on all single and split supplies n Micropower: 300A Supply Current Max with a total voltage of 2.5V to 18V. The ampli er draws less n Operating Temperature Range: 40C to 125C than 300A of quiescent current and has reverse-battery n Gain Bandwidth Product: 1.25MHz protection, drawing negligible current for reverse supply n Slew Rate: 0.42V/s voltages up to 18V. n Low Input Offset Voltage: 800V Max The input range of the LT1783 includes ground, and a n Single Supply Input Range: 0V to 18V unique feature of this device is its Over-The-Top opera- n High Output Current: 18mA Min tion capabilitity with either or both of its inputs above the n Speci ed on 3V, 5V and 5V Supplies positive rail. The inputs handle 18V both differential and n Output Shutdown on 6-Lead Version common mode, independent of supply voltage. The input n Reverse-Battery Protection to 18V stage incorporates phase reversal protection to prevent n High Voltage Gain: 1500V/mV false outputs from occurring even when the inputs are 9V n Low Pro le (1mm) ThinSOT Package below the negative supply. The LT1783 can drive loads up to 18mA and still maintain APPLICATIONS rail-to-rail capability. A shutdown feature on the 6-lead n version can disable the part, making the output high Portable Instrumentation n impedance and reducing quiescent current to 5A. The Battery- or Solar-Powered Systems n LT1783 op amp is available in the 5- and 6-lead SOT-23 Sensor Conditioning n packages.
