Activates the A section of the tens display.
Activates the F section of the tens display.
Activates the E section of the tens display.
Activates the D section of the hundreds display.
Activates the B section of the hundreds display.
Activates the F section of the hundreds display.
Activates the E section of the hundreds display.
Activates both halves of the 1 in the thousands display.
Activates the negative polarity display.
LCD backplane drive output (TC7116/TC7116A).
Digital ground (TC7117/TC7117A).
Activates the G section of the hundreds display.
Activates the A section of the hundreds display.
Activates the C section of the hundreds display.
Activates the G section of the tens display.
Negative power supply voltage.
Integrator output. Connection point for integration
capacitor. See Integration Capacitor section for
additional details.
Integration resistor connection. Use a 47 k
resistor for
200 mV full-scale range and a 470 k
resistor for 2V
full-scale range.
The size of the auto-zero capacitor influences system
noise. Use a 0.47
μ
F capacitor for 200 mV full scale and
a 0.047
μ
F capacitor for 2V full scale. See Auto-Zero
Capacitor paragraph for more details.
The analog LOW input is connected to this pin.
The analog HIGH input is connected to this pin.
This pin is primarily used to set the analog common-
mode COMMON voltage for battery operation or in
systems where the input signal is referenced to the
power supply. See Analog Common paragraph for more
details. It also acts as a reference voltage source.
