values of feedback resistances (lower current DACs). This
input pole can be compensated for by creating a feedback
zero with a capacitance across the feedback resistance, if
necessary, to reduce overshoot. For 2.0 kW of feedback
resistance, the MC34071 series can settle to within 1/2 LSB
of 8−bits in 1.0 ms, and within 1/2 LSB of 12−bits in 2.2 ms
for a 10 V step. In a inverting unity gain fast settling
configuration, the symmetrical slew rate is ±13 V/ms. In the
classic noninverting unity gain configuration, the output
positive slew rate is +10 V/ms, and the corresponding
negative slew rate will exceed the positive slew rate as a
function of the fall time of the input waveform.

inherently fast, contributing to the bipolar amplifier’s high
gain bandwidth product and fast settling capability. The
associated high frequency low output impedance (30 W typ
@ 1.0 MHz) allows capacitive drive capability from 0 pF to
10,000 pF without oscillation in the unity closed loop gain
configuration. The 60° phase margin and 12 dB gain margin
as well as the general gain and phase characteristics are
virtually independent of the source/sink output swing
conditions. This allows easier system phase compensation,
since output swing will not be a phase consideration. The
high frequency characteristics of the MC34071 series also
allow excellent high frequency active filter capability,
especially for low voltage single supply applications.

dress, component placement, and PC board layout should be
exercised for optimum frequency performance. For
example, long unshielded input or output leads may result in
unwanted input−output coupling. In order to preserve the
relatively low input capacitance associated with these
amplifiers, resistors connected to the inputs should be
immediately adjacent to the input pin to minimize additional
stray input capacitance. This not only minimizes the input
pole for optimum frequency response, but also minimizes
extraneous “pick up” at this node. Supply decoupling with
adequate capacitance immediately adjacent to the supply pin

types of decoupling capacitors exhibit great impedance

such conditions, it is important not to allow the device to
exceed the maximum junction temperature rating. Typically
for ±15 V supplies, any one output can be shorted
continuously to ground without exceeding the maximum
temperature rating.
