Hot-selling and scarce LTC1541CS8-PBF Amplifier Comparator Reference IC SOP8 spot stock

Product Descriptions

The LTC^®1541/LTC1542 combine a micropower amplifier, comparator and bandgap reference (LTC1541) in an8-pin package . The part operates from a single 2.5V to12.6V or dual ±1.25V to ±6.3V supply with a typical supplycurrent of 5µA . Both the op amp and comparator featurea common mode input voltage range that extends from thenegative supply to within 1.3V of the positive supply.Theop  amp  output  stage  swings  from  rail-to-rail .  Thecomparator’s inverting input is internally connected to thereference output (LTC1541).

The  reference  output  voltage  is  1.2V  ±1%  over  theextended  temperature  range .  The  output  can  drive  abypass capacitor of up to 0.01µF without any oscillations .It can also source up to 2mA and sink up to 20µA .

The op amp is internally compensated to be unity-gainstable with typical GBW at 12kHz and slew rate of 8V/ms .The comparator has ±2.25mV of internal hysteresis toensure clean output switching, even with slow movinginput signals .

The LTC1541/LTC1542 are available in MSOP and SO-8packages . For space-limited applications, the LTC1541/LTC1542  are  available  in  a  3mm x  3mm  low  profile(0 .8mm) dual fine-pitch leadless package (DFN).
