AGND
-5.2V Logic Supply.
External resistor to set the full scale output current. IFS = 32 x (CTRL AMP IN/RSET). Typically 1960Ω .
Analog Ground supply current return pin.

OUT
Current Output pin.
Complementary Current Output pin.
-5.2V Analog Supply.
Reference Input pin. Typically connected to CTRL AMP OUT and a 0.1µF capacitor should be connected to
AVEE to bypass the reference voltage. Provides a reference for the current switching network.
Control Amplifier Output. Used to convert the internal reference or an external signal to the precision reference
current.
REF OUT Internal Reference Output. Output of the internal -1.25V (typical) bandgap voltage reference.
CTRL AMP IN Control Amplifier Input. High impedance, inverting input of the reference control/buffer amplifier.
