The Fujitsu Microelectronics MB88346L is a 12-channel 8-bit D/A converter capable of low-voltage operation that has amplifiers built into each of the 12 analog output lines to deliver heavy-current drive capability.
The use of serial data input means that only three control lines are required, and enables cascade connection of multiple MB88346L chips.
The MB88346L is suitable for applications such as electronic volume controls and replacing trimmer potentiometers in tuning systems. In addition, the MB88346L is both function-compatible and pin-compatible the currently used MB88346B, making it easy to reduce the voltage level of a system by simply replacing the MB88346B with the MB88346L.

TA8132AN, TA8132AF and TA2012N, TA2012F are the AM / FM IF+ST DET system ICs, which are designed for DTS radios. These are included many functions and these can be used for digital tuning system with IF counter.

-  Built−in AM / FM IF and FM stereo PLL multiplex decoder.
-  Suitable for combination with digital tuning system which is included IF counter.
○ One terminal type AM / FM IF count output (auto stop signal) for IF counter of digital tuning system.
FM: 10.7MHz or 1.3375MHz (1 / 8 dividing) changeable by external switch
AM: 450kHz
○ Built−in mute circuit for IF count output.
It is controlled by the IF request signal from digital tuning system, Pin(8) level:
High → come out
Low → non output
○ Adjustable for IF count output sensitivity by external resistance of pin(2).
-  For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector circuit and FM ST DET VCO circuit.
-  S curve characteristics of FM detection output in TA8132AN, TA8132AF and TA2012N, TA2012F are reverse to each other.
TA8132AN, TA8132AF: Reverse characteristic. TA2012N, TA2012F: Normal characteristic.
-  Built−in one terminal type AM low cut circuit.
-  TA2053F is reverse pin type of TA2012F.
-  Operating supply voltage range (Ta = 25°C) VCC (opr.) = 1.8~8.0V
