GENERAL D ESCRIP TIO N  
T he LOGDAC® AD7118 is a CMOS multiplying D/A con-  
verter which attenuates an analog input signal over the range  
0 to –85.5 dB in 1.5 dB steps. T he analog output is determined  
by a six-bit attenuation code applied to the digital inputs.  
Operating frequency range of the device is from dc to several  
hundred kHz.  
T he device is manufactured using an advanced monolithic  
silicon gate thin-film on CMOS process and is packaged in a  
14-pin dual-in-line package.
