    Ionization Smoke Detector IC
    Product Specification General Description Features The RE46C112 is an ionization type smoke detector IC.
    It is intended for applications using ionization type
    chambers to detect smoke. When enabled, VOUT is Вј
    of either the DETECT input or VDD depending on the
    status of the SELECT input. When the Select input is
    allowed to float the circuit is in the low current mode
    with only the guard amplifier enabled.
    Utilizing low power CMOS technology the RE46C112
    was designed for use in smoke detectors that comply
    with Underwriters Laboratory Specification UL217. Guard Outputs for Ion Detector Input
    В± 0.75pA Detect Input Current
    Microprocessor A/D Compatible Analog Output
    Low Quiescent Current Consumption (<10uA)
    Available in 8L PDIP or 8L N SOIC
    2000V ESD Protection (HBM)
    Available in Standard Packaging or RoHS
