Table 6-1 Pin Functions
PIN TYPE DESCRIPTION
NAME NO.
FDA_IN– 15 Input Connection to output driver summing node.
FDA_IN+ 6 Input Connection to output driver summing node.
G02– 9 Input Connection to gain network. Short to OUT– for output stage gain GOUT of 0.2 V/V.
G02+ 12 Input Connection to gain network. Short to OUT+ for output stage gain GOUT of 0.2 V/V.
IN– 1 Input Negative (inverting) input.
IN+ 4 Input Positive (noninverting) input.
NC 8 — No connect
OUT– 10 Output Negative Output
OUT+ 11 Output Positive Output
RG 2,3 — Gain setting pin. Place a gain resistor between pin 2 and pin 3.
VCLAMP– 5 Input Level set for output clamp value. Connect either to an external supply that is at least 1.5 V above VS– or connect to VS– if clamping function is not required.
VCLAMP+ 16 Input Level set for output clamp value. Connect either to an external supply that is at least 1.5 V below VS+ or connect to VS+ if clamping function is not required.
VOCM 13 Input Level set for output common mode value.
VS– 7 Power Negative supply
VS+ 14 Power Positive supply
Thermal Pad Thermal pad — The thermal pad must be soldered to the printed-circuit board (PCB). Connect thermal pad to a plane or large copper pour electrically connected to the most negative supply or VS–.
