Analog Power - VA
Pin 14, Input
Function:
Analog power supply. Typically 3 to 5VDC.
Analog Ground - AGND
Pin 13, Input
Function:
Analog ground reference.
Analog Output - AOUTA and AOUTB
Pins 12 and 15, Output
Function:
The full scale analog output level is specified in the Analog Characteristics specifications table.
Reference Ground - REF_GND
Pin 11, Input
Function:
Ground reference for the internal sampling circuits. Must be connected to analog ground.
Positive Voltage Reference - FILT+
Pin 9, Output
Function:
Positive reference for internal sampling circuits. External capacitors are required from FILT+ to analog
ground, as shown in Figure 6. The recommended values will typically provide 60 dB of PSRR at 1 kHz
and 40 dB of PSRR at 60 Hz. FILT+ is not intended to supply external current. FILT+ has a typical source
impedence of 250 kΩ and any current drawn from this pin will alter device performance.
Quiescent Voltage - VQ
Pin 10, Output
Function:
Filter connection for internal quiescent reference voltage, typically 50% of VA. Capacitors must be con-
nected from V_Q to analog ground, as shown in Figure 6. V_Q is not intended to supply external current. V_Q
has a typical source impedence of 250 kΩ and any current drawn from this pin will alter device perfor-
mance.
