Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge
of suffering physical damage, and therefore the product must be used under conditions that ensure
that the absolute maximum ratings are not exceeded.


Description

The PC2807 and 2807A are semiconductors integrated circuit developed as preamplifiers for the receiver module of infrared remote controllers. These preamplifiers can be directly connected to a PIN photodiode, and integrate a high-gain first stage amplifier, limiter, bandpass filter, detector circuit, and waveform-shaping circuit on a single chip.
