Hi Howard, Thank you for your query. The price of an 8-channel DAC is less than 8x that of a single-channel DAC. For example, the 1kU web price of DAC80508 is $9.99 while the same for DAC80501 is $3.44. However, if your price target is still lower, you can go with another approch to implement a mutichannel output using Single-channel DAC + S/H. You can get details of that from this app note: www.ti.com/.../sbaa326.pdf Hope that answers your query. Regards, Uttam Sahu Applications Engineer, Precision DACs
