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
