YM3025

The YM3025 is a floating D/A converter with the 2-channel serial and 16-bit 2's complement input. YM3025 can produce analog output (16-bit dynamic range) which has 10-bit mantissa and 7-step exponent characteristic for the input digital signal.There are some features of YM3025 as follows.First is +5 V single power supply including op-amp.The second is capable of processing PCM sound source up to 2 channels.Then is equipped with a built-in analog switch for sample hold.Next is lower noise and less harmonic distortion and outstanding temperature characteristic.The last one is made by monolithic process of highly accurate thin film resistor and CMOS and enclosed in 16-pin plastic flat package.

What comes next is about the absolute maximum ratings of YM3025.The VDD (power supply voltage) is from -0.3 V to +15.0 V.The high-level input voltage is VDD+0.3 V.The low-level voltage is VSS-0.3 V.The Top (operating ambient temperature) is from 0 to +70.The Tstg (storage temperature) is from -50 to +125.Then is about the recommended operating conditions.The minimum VDD (power supply voltage) is 4.75 V,the typicall is 5.0 V and the maximum is 5.25 V.The minimum Top (operating temperature) is 0 and the maximum is 70.The minimum input signal voltage is 0 V and the maximum is VDD V for CLOCK, SD, SMP1,2 and ICL.

The following is about the DC characteristics of YM3025.The minimum VIH (high level input voltage) is 3.3 V and the maximum VIL (low level input voltage) is 1.0 V.The maximum IIN (input current) is 1 A at VDD=5.0 V.The typical VOUT (analog output voltage) is 1/3*VDD Vp-p.The maximum IDD (supply current) is 6 mA at VDD=5.0 V.
