Brief Description
Bipolar Linear Integrated Circuit Silicon Monolithic
3V AM/FM 1 Chip Tuner IC (for Digital Tuning System)
TA2149BN, TA2149BFN are AM/FM 1 chip tuner ICs, designed for portable Radios and 3 V Headphone Radios. These ICs are suitable for Digital Tuning System Applications. FM Local Oscillation Voltage is set up low relativity, for NEW FCC.
Specifications and features
- Adjustable for IF count output sensitivity by external resistance of pin 17 (FM only)
- One terminal type AM/FM IF count output for IF counter of Digital Tuning System
- Built-in Mute Circuit for IF count output
- For adopting ceramic Discriminator, it is not necessary to adjust the FM Quad Detector Circuit
- Built-in FM MPX VCO circuit
- Built-in one terminal type AM/FM Local Oscillator Buffer Output for Digital Tuning System Applications
- Built-in 1/16 Pre-scaler for FM Local OSC Buffer
- Built-in AM Low cut circuit
- Low supply current. (VCC= 3 V, Ta = 25°C)
ICCq(FM) = 13 mA (Typ.)
ICCq(AM) = 8.5 mA (Typ.) - Operating Supply voltage range: VCC= 1.8~7 V (Ta = 25°C)
Application Scenarios
This electronic component model is suitable for portable Radios, 3 V Headphone Radios, and Digital Tuning System Applications. It can be used in various electronic devices and equipment that require AM/FM tuning.
