Description

INPT

Input Current. Pin sources current only.

VSET

Sets Voltage at INPT (Gain = 1). Range 0 V to VPOS − 1.0 V for VPOS < 6.5 V. For VPOS ≥ 6.5 V range, VPOS − 6.5 V to

VPOS − 1 V. Optional shielding of INPT trace.

SREF

Reference Voltage for VSET. Internally generated at VPOS − 1.0 V through 20 kΩ. Can be shorted to VSET for

standard mirror operation.

COMM

Analog Ground.

RLIM

External Resistor to VPOS. Sets current limit at INPT from 1 mA to 16 mA. ILIM = 48 V/(RLIM + 3 kΩ).

VPOS

Positive Supply (2.7 V to 8.0 V).

N/C

Optional Shielding of IOUT Trace. No connection to die.

IOUT

Output Current. Mirrors current at INPT with a gain of 1.0. Sources current only.

PADDLE

Internally connected to COMM, solder to ground.
