Pin Functions PIN TYPE(2) DESCRIPTION NAME DGK RUN RGT(1) FB– — — 1 O Inverting (negative) output feedback FB+ — — 4 O Noninverting (positive) output feedback IN– 1 6 3 I Inverting (negative) amplifier input IN+ 8 4 2 I Noninverting (positive) amplifier input NC — 2, 8 — — No internal connection OUT– 5 1 11 O Inverting (negative) amplifier output OUT+ 4 9 10 O Noninverting (positive) amplifier output PD 7 3 12 I Power down. PD = logic low = power off mode; PD = logic high = normal operation. VOCM 2 7 9 I Common-mode voltage input VS– 6 5 13, 14, 15, 16 P Negative power-supply input VS+ 3 10 5, 6, 7, 8 P Positive power-supply input (1) Solder the exposed RGT package thermal pad to a heat-spreading power or ground plane. This pad is electrically isolated from the die, but must be connected to a power or ground plane and not floated. (2) I = input, O = output, P = power.
