A quiet,
1420/1430 are relatively straightforward.
solid ground reference, stiff voltage supplies, and ad-
equate supply bypassing are all that is required to
achieve excellent performance out of both ICs. Both
devices are stable into any capacitive load, and the
maximum capacitance is limited only by slew rate
and frequency response considerations.
For the purposes of the frequency response calcu-
lation, the line driver’s 50
sense resistors can be
lumped into a single 100

As an example, one manufacturer supplies a
