TA2029FN / N
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2029FN,TA2029N
FM F / E + AM / FM IF + PW IC
For Digital Tuning System
The TA2029FN / N are AM / FM single chip radio system ICs
which are designed for monaural radio.
These ICs have many functions and can be used for digital tuning
system.
Features
· Built−in FM F / E, AM / FM IF, electronic volume and power
amplifier.
· Suitable for combination with digital tuning system which has
IF counter.
· AM / FM IF output for IF counter.
FM: 1.3375MHz (1 / 8 IF)
AM: 450kHz
· AM / FM oscillation buffer outputs.
· Auto stop sensitivity at the searching mode is adjustable by
external resistances. (pin (5), pin(6) )
· Adjustment−free type FM detector.
· Built−in AF power amplifier, electronic volume and audio
muting circuits.
· Detector outputs FM / AM are independent each other.
· Po = 100mW (typ.), THD = 10% (FN: 3V / 8Ω)
Po = 500mW (typ.), THD = 10% (N: 6V / 8Ω)
· Operating supply voltage range
: VCC = 1.8~8V (Ta = 25°C)
Weight:
SSOP30−P−300−0.65: 0.17g (typ.)
SDIP30−P−400−1.78: 2.2g (typ.)
