LTC6752MPS5#TRMPBF

LTC®6752 is a 280MHz, 2.9ns comparator with rail-to-rail inputs and CMOS outputs. This comparator exhibits low propagation delays of 2.9ns, and fast rise/fall times of 1.2ns. There are a total of 5 members in the LTC6752 family, with different options for separate input and output supplies, shutdown, output latch, adjustable hysteresis, complementary outputs, and package. This comparator has rail-to-rail inputs that operate from 2.45V, up to 3.5V or 5.25V, depending on the option. The outputs are CMOS and the separate supply options can operate down to 1.71V, allowing for directly interfacing to 1.8V logic devices. Application includes clock and data recovery, level shifting, high speed data acquisition systems, window comparators, high speed line receivers, fast crystal oscillators, time of flight measurements, time domain reflectometry.

• 280MHz typical toggle rate (100mVP-P input, TA = 25°C)
• 2.9ns typical low propagation delay (VOVERDRIVE = 50mV, TA = 25°C)
• Rail-to-rail inputs extend beyond both rails
• Output current capability is ±22mA, typical low quiescent current is 4.5mA (TA = 25°C)
• Shutdown pin for reduced power, output latch and adjustable hysteresis
• Complementary outputs, direct replacement for ADCMP60X family
• Supply voltage range from 2.45 to 3.5V (TA = 25°C, VCC = 2.5V)
• 69dB typical common mode input range, low VCM region (VCM = VEE -0.2V to VCC -1.5V)
• 74dB typ input power supply rejection ratio (VCM = 0.3V, VDD = 2.5V, VCC Varied from 2.45 to 5.25V)
• 5 lead plastic TSOT-23 package, operating temperature range from -55°C to 125°C
