The LTC1541/LTC1542 combine a micropower amplifier, comparator and bandgap reference (LTC1541) in an 8-pin package. The part operates from a single 2.5V to 12.6V or dual ±1.25V to ±6.3V supply with a typical supply current of 5µA. Both the op amp and comparator feature a common mode input voltage range that extends from the negative supply to within 1.3V of the positive supply. The op amp output stage swings from rail-to-rail. The comparator's inverting input is internally connected to the reference output (LTC1541).
The reference output voltage is 1.2V ±1% over the extended temperature range. The output can drive a bypass 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-gain stable with typical GBW at 12kHz and slew rate of 8V/ms. The comparator has ±2.25mV of internal hysteresis to ensure clean output switching, even with slow moving input signals.
The LTC1541/LTC1542 are available in MSOP and SO-8 packages. For space-limited applications, the LTC1541/LTC1542 are available in a 3mm × 3mm low profile (0.8mm) dual fine-pitch leadless package (DFN).
