TC9293F

The TC9293F is designed as a 2nd order - modulation system 1bit DA converter with a built-in 8 times over sampling FIR type digital filter developed for digital audio equipment. As the TC9293F IC is small package, SSOP24 and SDIP24, and the analog filter has been incorporated, it is able to output a direct analog wave form and construct small the digital filter, the analog output unit at a low price.

TC9293F has many features. (1)Built-in 8 times over-sampling digital filter. (2)Low voltage operate (3.0V to 5.5V). (3)Built-in digital de-emphasis filter. (4)In serial control mode, output amplitude can be set in 128steps of resolution using microcontroller command. (5)In parallel control mode, soft mute can be set for the output signal in 64setps in 20ms. (6)Support double speed operation. (7)Sampling frequency 32kHz, 44.1kHz, 48kHz. And so on.

Some absolute maximum ratings of TC9293F 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 200mW. (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 TC9293F are concluded as follow. (1)Its power supply voltage would be min 4.5V and typ 5.0V and max 5.5V. (2)Its power dissipation would be typ 12mA and max 20mA. (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 level would be min -10uA and max 10uA. (6)Its input current low level would be min -10uA and max 10uA. (7)Its S/N ratio would be min 88dB and typ 96dB. (8)Its cross-talk would be typ -95dB and max -90dB. And so on. If you have any question or suggestion or want to know more information of TC9293F please contact us for details. Thank you!
