NE/SA604A

The NE/SA604A is an improved monmlithic low-power FM IF system incorporating two limiting intermediate frequency amplifiers,quadrature detector,muting,logarithmic received signal strength indictor,and voltage regulator.The NE/SA604A features higher IF bandwidth (25MHz) and temperature compensated RSSI and limiters permitting higher performance application compared with the NE/SA604.The NE/SA604A is available in a 16-lead dual-in-line plastic and 16-lead SO (surface-mounted miniature) package.

The NE/SA604A has 6 features.The first one is low power consumption:3.3mA typical.The second one is temperature compensated logarithmic received signal strength indicator (RSSI) with a dynamic range in excess of 90dB.The third one is two sudio output-muted and ummuted.The fourth one is low extermal component count;suitable for crystal/ceramic filters.The fifth one is excellent sensitivity:1.5V across input pins (0.22V into 50 matching network) for 12dB SINAD (signal to noise and distortion ratio) at 455kHz.The sixth one is SA604A meets cellular radio specifications.

The NE/SA604A has some absolute maximum ratings.When symbol is VCC,the parameter is single supply voltage,the rating is 9,the unit is V.When symbol is Tstg,the parameter is storage temperature range,the rating is -65 to +150,the unit is .When symbol is TA,the parameter is operating ambient temperature range SA604A,the rating is -40 to +85,the unit is .When symbol is TA,the parameter is operating ambient temperature range NE604A,the rating is 0 to +70,the unit is .
