描述
The LTC8701/8702/8703/8704 devices are single-, dual-, and quad- channel
comparators with push-pull output that are ideal for power-sensitive,
low-voltage applications. Featuring a nano-power (typical 310 nA), fast
12 μs propagation delay, and a wide range of supply voltages from
1.7 V to 5.5 V with rail-to-rail common-mode voltage range makes the
LTC8701/8702/8703/8704 an ideal choice for a wide variety of
portable electronics applications, such as handsets, tablets, notebooks
and portable devices that have extremely power constraints and tight
board space.
The output of the LTC8701/8702/8703/8704 pulls to
within 0.1 V of either supply rail without external pull-up circuitry,
making these devices ideal for interface with both CMOS and TTL logics.
All input and output pins can tolerate a continuous short-circuit fault
condition to either rail. Internal hysteresis ensures clean output
switching, even with slow-moving input signals.
The
LTC8701/LTC8703 (single) is available in both SOT23-5L and SC70-5L
packages. The LTC8702 (dual) is offered in SOIC-8L, MSOP-8L and DFN-8L
packages. The quad-channel LTC8704 is offered in both SOIC-14L and
TSSOP-14L packages. All devices are rated over -40 ℃ to +85 ℃ industrial
temperature range
