That it will. I tested the worst case scenario of a full scale deflection from 0% to 100% duty;
**broken link removed**
As you can see above, it takes 1200uS (1.2mS) to ramp from 0V to 5V. This is a fall back of the RC circuit as the capacitive time constant needs to be taken into account
Good for your everyday DAC output, but audio will need much a faster response.
On another note, I have used the
MCP3002 with decent results. Single supply operation: 2.7V - 5.5V, SPI serial interface, and 200 ksps max sampling rate at VDD = 5V.
You'll need a power opamp to drive a load of any size though.
