Dynamic Response

Section

(1)

Includes input amplifier, but excludes RSET tolerance. Offset current is the deviation from the current ratio of ISET to IIS (output current).

(2)

See Typical Characteristics.

(3)

Span is the change in output current resulting from a full-scale change in input voltage.

(4)

Within compliance range limited by (+VVSP – 2V) +VDS required for linear operation of QEXT.

(5)

See Application Information, Input Voltage section.
