LF13006 LF13007 Digital Gain Set February 1995 LF13006 LF13007 Digital Gain Set General Description The LF13006 and LF13007 are precision digital gain sets used for accurately setting non-inverting op amp gains Gains are set with a 3-bit digital word which can be latched in with WR and CS pins All digital inputs are TTL and CMOS patible The LF13006 shown below will set binary scaled gains of 1 2 4 8 16 32 64 and 128 The LF13007 will set gains of 1 2 5 10 20 50 and 100 (a mon attenuator sequence) In addition both versions have several taps and two unmitted matching resistors that allow customization of the gain The gains are set with precision thin film resistors The low...
