PIN DESCRIPTION

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 k

Ω 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-

has a typical source impedence of 250 k

Ω and any current drawn from this pin will alter device perfor-

mance.
