TC9237BF

The TC9237BF is designed as a 2nd order - modulation system 1bit DA converter with a built-in 8 times oversampling FIR type digital filter developed for digital audio equipment. As the de-emphasis function has been incorporation, TC9237BF is possible to configure the system for digital filtering through analogue output at a low price.

TC9237BF has six features. (1)Built-in 8 times over-sampling FIR type digital filter. (2)Over-sampling ratio (OSR) is 192fs. (3)Built-in digital de-emphasis filter. (4)Simultaneous outputs to L-ch and R-ch. (5)Compatible with fs=32K, 44.1K, 48kHz. (6)Compatible with double speed operation. Those are all the main features.

Some absolute maximum ratings of TC9237BF have been concluded into several points as follow. (1)Its power supply voltage would be from -0.3 to 6.0V. (2)Its input voltage would be from -0.3V to Vdd+0.3V. (3)Its power dissipation would be 600mW. (4)Its storage temperature range would be from -55°C to 150°C. (5)Its operating temperature range would be from -35°C to 85°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of TC9237BF are concluded as follow. (1)Its power supply voltage would be min 4.5V and typ 5.00V and max 5.5V. (2)Its power dissipation would be typ 25mA and max 45mA. (3)Its input voltage high would be min 0.7Vdd and max Vdd. (4)Its input voltage low would be min 0V and max 0.3Vdd. (5)Its input current high would be min -10uA and max 10uA. (6)Its input current low would be min -10uA and max 10uA. (7)Its pull-up resistor would be typ 130kohms. (8)Its noise distortion would be typ -87dB and max -78dB. (9)Its S/N ratio would be min 88dB and typ 98dB. (10)Its dynamic range would be min 88dB and typ 95dB. And so on.
