TC9287AF

The TC9287AF is a kind of 2'nd order - modulation 1 bit AD/DA converter for digital audio equipment. The TC9287AF has built-in 2 channel AD/DA converter, and digital and analog filter, so can construct hi-performance and low cost AD/DA converter system. There are some features about the TC9287AF as follows: (1)built in input and output digital/analog filter circuit, so external filter is CR filter; (2)operating voltage: 5 V; (3)power dissipation: 250 mW (VDD=5 V) (at ADOFF mode, 190 mW (VDD=5 V)); (4)package: QFP44-P-1010-0.80.

The following is about the maximum ratings of TC9287AF (Ta=25): (1)supply voltage, VDD: -0.3 to 6.0 V; (2)supply voltage, VDA1: -0.3 to 6.0 V; (3)supply voltage, VDA2: -0.3 to 6.0 V; (4)supply voltage, VDX: -0.3 to 6.0 V; (5)input voltage, Vin: -0.3 to VDD+0.6 V; (6)power dissipation, PD: 250 mW; (7)operating temperature, Topr: -30 to 85; (8)storage temperature, Tstg: -55 to 150.

The last one is about the electrical characteristics of TC9287AF(unless otherwise specified, Ta=25, VDD=VDX=VDA=5 V): (1)operating supply voltage, VDD: 4.5 V min, 5.0 V typ and 5.25 V max at Ta=-35 to 85; (2)operating supply voltage, VDX: 4.5 V min, 5.0 V typ and 5.25 V max at Ta=-35 to 85; (3)operating supply voltage, VDA1: 4.5 V min, 5.0 V typ and 5.25 V max at Ta=-35 to 85; (4)operating supply voltage, VDA2: 4.5 V min, 5.0 V typ and 5.25 V max at Ta=-35 to 85; (5)power dissipation, IDD: 50 mA typ and 90 mA max at XI=16.9344 MHz, ADOFF="L"; (6)power dissipation (at ADOFF=OFF), IDD: 35 mA typ and 63 mA max at XI=16.9344 MHz, ADOFF="H"; (7)input voltage, "H" level, VIH: 3.5 V min; (8)input voltage, "L" level, VIL:1.5 V max; (9)input current, IIN: -10A min and 10A max; (10)pull up/down reseter, RU/D: 60 k min and 150 k max.
