YM3012

The YM3012 is a kind of floating D/A converter with serial input for two channels. It can generate analog output (dynamic range 16 bits) of 10-bit mantissa section and 3-bit exponent section on the basis of input digital signal.

There are some features of YM3012 as follows: (1)an external buffer operational amplifier is provided to obtain analog output easily; (2)a wide dynamic range with 16 bits; (3)compatible with PCM audio sources of up to 2 channels; (4)built-in sample hold analog switches; (5)it is possible to obtain low noise, low harmonic distortion and good temperature characteristics; (6)monolithic chip with high precision thin film resistor and CMOS housed in a 16-pin plastic DIL package.

What comes next is about the absolute maximum ratings of YM3012: (1)supply voltage: -0.3 to +15.0 V; (2)high level input voltage: VDD+0.3 V; (3)low level input voltage: VSS-0.3 V; (4)ambient operating temperature: 0 to 70; (5)storage temperature: -50 to +125. Then is about the DC characteristics: (1)high level input voltage, VIH: 3.3 V min at VDD=5.0 V; (2)low level input voltage, VIL: 1.0 V max at VDD=5.0 V; (3)input current, IIN: 10-3 A max when VDD=10.0 V; (4)power current, IDD: 6 mA max when VDD=5.0 V.
