TC9276F

The TC9276F is a kind of 2'nd order - modulation system 1 bit DA converter incorporating an 8-times over sampling digital filter developed for digital audio equipment. Because the IC is small package (SOP20) and includes the de-emphasis filter which has been incorporated, TC9276F is possible to constitute reducing the size and cost of the DA converter. There are some features as follows: (1)built-in 8-times over sampling digital filter; (2)low voltage operation (3.3 V); (3)built-in digital de-emphasis filter; (4)over sampling ratio (OSR) is 192 fs; (5)sampling frequency (fs): 44.1 kHz; (6)support soft mute function.

The following is about the maximum ratings of TC9276F(Ta=25): (1)supply voltage, VDD: -0.3 to 6.0 V; (2)supply voltage, VDA: -0.3 to 6.0 V; (3)supply voltage, VDX: -0.3 to 6.0 V; (4)input voltage, Vin: -0.3 to VDD+0.3 V; (5)power dissipation, PD: 200 mW; (6)operating temperature, Topr: -25 to 85; (7)storage temperature, Tstg: -55 to 150.

The last one is about the electrical characteristics of TC9276F (unless otherwise specified, Ta=25, VDD=VDX=VDA=5 V): (1)operating supply voltage 1, VDD: 4.5 V min, 5.0 V typ and 5.5 V max at Ta=-35 to 85; (2)operating supply voltage 1, VDX: 4.5 V min, 5.0 V typ and 5.5 V max at Ta=-35 to 85; (3)operating supply voltage 1, VDA: 4.5 V min, 5.0 V typ and 5.5 V max at Ta=-35 to 85; (4)operating supply voltage 2, VDD: 3.3 V min, 3.5 V typ and 5.5 V max at Ta=-15 to 55 (operating frequency fopr=16.9 MHz); (5)operating supply voltage 2, VDX: 3.3 V min, 3.5 V typ and 5.5 V max at Ta=-15 to 55 (operating frequency fopr=16.9 MHz); (6)operating supply voltage 2, VDA: 3.3 V min, 3.5 V typ and 5.5 V max at Ta=-15 to 55 (operating frequency fopr=16.9 MHz); (7)power dissipation, IDD: 12 mA typ and 20 mA max at XI=16.9 MHz; (8)input voltage, "H" level, VIH: VDD*0.7 V min and VDD V max; (9)input voltage, "L" level, VIL: 0 V min and VDD*0.3 V max; (10)input current, "H" level, IIH: -10A min and 10A max; (11)input current, "L" level, IIL: -10A min and 10A max.
