PIN DESCRIPTION
Piezo buzzer output. Whenever BZEN is connected to V+ and
differential inputs are tied together, BZ will generate a 5KHz sound
output.
Buzzer control slave input. This pin is internally pulled-down to
TEST.See BZ
Digital GND. Pull high to V+ all LCD segments will be activated.
Crystal oscillator connection. (RC)
Hold control pin. When it receives a negative mud pulse, display hold;
Receive again then function disabled.
Crystal oscillator connection. (output)
Crystal oscillator connection. (input)
Positive supply voltage
LCD segment drive (unit)
LCD segment drive (decade)
LCD segment drive (hundred)
LCD segment drive (thousand). When the readout exceeds 1999, AB4
drive the segment of thousand to display ‘1’ for showing excess.
LCD segment drive. (minus ‘-‘)
LCD common drive.
LCD segment drive. (low battery)
Negative supply voltage. Connecting to battery negative terminal.
Integrator output.
Integration register connection
Auto-zero capacitor connection
Analog low input signal
Analog high input signal
Set the common-mode voltage for the system
Negative capacitor connection for on-chip A/D converter
Positive capacitor connection for on-chip A/D converter
Low differential reference input connection.
High differential reference input connection
