P IN CO NFIGURATIO N

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.
