GENERAL DESCRIPTION
FEATURES
● 5 to 8 V power supply and an alternative 12 V power supply● Low power consumption (200 mW) at 5 V supply voltage
● New AC-coupled wideband IF-amplifier (high dynamic ranges, less intermodulation)
● In-phase wideband AM demodulator without external reference circuit
● Reduced THD figures even for low AF frequencies (typical 1%)
● Stabilizer circuit for ripple rejection and constant output signals
● All pins are ESD protected QUICK REFERENCE DATA PARAMETER Supply voltage (pin 14) Supply voltage (pin 11) Supply current Minimum IF input (RMS value) IF control range AF output signal (RMS value) Signal plus weighted-noise to weighted-noise ratio (CCIR 468-3) PACKAGE OUTLINE 16-lead DIL; plastic (opposite bent leads) (SOT38WBE); SOT38-1; 1996 December 4.
