Trilithic's patented high accuracy programmable attenuators allow the user complete flexibility of specifying a unit to meet a particular application. The low insertion loss, superior accuracy, and affordability make the series ideal for volume applications. Individual pad (cell) values range from 0.1 dB to 32 dB. Typical configurations are binary steps, such as 1, 2, 4, 8 dB, etc., but any pad sequences are available within the normal range of 0.1 dB to 32 dB. The minimum number of cells is one, while the maximum is eight. The convenience of TTL control is available as an option.
