TDA1596
Description
TDA1596 The TDA1596 provides IF amplification, symmetrical quadrature demodulation and level detection for quality home and car FM radio receivers and is suitable for both mono and stereo reception. It may also be applied to common front-ends, stereo decoders and AM receiver circuits.
Key Features
- Simulates behaviour of a ratio detector (internal field strength and detuning-dependent voltage for dynamic AF signal muting)
- Mono/stereo blend and field strength indication control voltage
- Three-state mode switch for FM, mute-on / FM, mute-off / FM-off
- Internal compensation of AF signal total harmonic distortion (THD)
- Two open collector stop pulse outputs for microcomputer tuning control (can be one stop pulse output by wired-ANDing)
- Internal reference voltage source
- Built-in hum and ripple rejection circuits QUICK REFERENCE DATA PARAMETER Supply voltage (pin 1) Supply current (pin 1) AF output voltage (RMS value) Signal-to-noise ratio V18(rms) = 10 mV V18(rms) = 10 mV; fm = 400 Hz; ∆f = 75 kHz Total harmonic distortion V18(rms) = 10 mV; fm = 1 kHz; I7 = 0 mA; ∆f = 75 kHz; FM mute on; without de-emphasis; without detuning Operating ambient temperature range SEE ALSO DATA SHEET FOR TDA1596T PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 August
