Dual Display
1.1 Introduction
ES51955 configures a dual display LCD driver for DMM applications. The dual display
includes first-display and second-display. Each display has 4 digits to show up to 5000
counts. The simplified representation of dual display is shown below. First-display usually
shows Volts readings in ACV/DCV mode or Hz readings in Frequency mode.
Second-display usually shows Amps/Hz readings in ACA/DCA mode or Duty-cycle
readings in Frequency mode. By the dual display feature, ES51955 can shows Amps and
Volts readings at the same time. Other features achieved by dual display will be introduced
in later sections. The full LCD configuration is shown at
section 3.5
of
page 25.
