GENERAL DESCRIPTION
The AD713 is a quad operational amplifier, consisting of four
AD711 BiFET op amps. These precision monolithic op amps
offer excellent dc characteristics plus rapid settling times, high
slew rates, and ample bandwidths. In addition, the AD713 provides
the close matching ac and dc characteristics inherent to amplifiers
sharing the same monolithic die. The single-pole response of
the AD713 provides fast settling: l μs to 0.01%. This feature,
combined with its high dc precision, makes the AD713 suitable
for use as a buffer amplifier for 12- or 14-bit DACs and ADCs.
It is also an excellent choice for use in active filters in 12-, 14-
and 16-bit data acquisition systems. Furthermore, the AD713
low total harmonic distortion (THD) level of 0.0003% and very
close matching ac characteristics make it an ideal amplifier for
many demanding audio applications. The AD713 is internally
compensated for stable operation at unity gain. The AD713J is
rated over the commercial temperature range of 0°C to 70°C.
The AD713A is rated over the industrial temperature of −40°C
to +85°C.
The AD713 is offered in 16-lead SOIC, 14-lead PDIP, and
14-lead CERDIP packages.

PRODUCT HIGHLIGHTS
1. The AD713 is a high speed BiFET op amp that offers
excellent performance at competitive prices. It upgrades
the performance of circuits using op amps such as the
TL074, TL084, LT1058, LF347, and OPA404.
2. Slew rate is 100% tested for a guaranteed minimum of
16 V/μs (J and A grades).
3. The combination of Analog Devices, Inc., advanced
processing technology, laser wafer drift trimming, and
well-matched ion-implanted JFETs provides outstanding
dc precision. Input offset voltage, input bias current and
input offset current are specified in the warmed-up
condition and are 100% tested.
4. Very close matching of ac characteristics between the four
amplifiers makes the AD713 ideal for high quality active
filter applications.

THEORY OF OPERATION
MEASURING AD713 SETTLING TIME
Figure 30 and Figure 31 show the dynamic response of the AD713
while operating in the settling time test circuit of Figure 29.
The input of the settling time fixture is driven by a flat-top pulse
generator. The error signal output from the false summing node
of A1, the AD713 under test, is clamped, amplified by Op Amp
A2, and then clamped again.

The error signal is thus clamped twice: once to prevent overload-
ing amplifier A2 and then a second time to avoid overloading
the oscilloscope preamp. A Tektronix oscilloscope preamp
Type 7A26 was carefully chosen because it recovers from the
approximately 0.4 V overload quickly enough to allow accurate
measurement of the AD713 1 μs settling time. Amplifier A2 is a
very high speed FET input op amp; it provides a voltage gain of
10, amplifying the error signal output of the AD713 under test
(providing an overall gain of 5).

POWER SUPPLY BYPASSING
The power supply connections to the AD713 must maintain a
low impedance to ground over a bandwidth of 4 MHz or more.
This is especially important when driving a significant resistive
or capacitive load because all current delivered to the load
comes from the power supplies. Multiple high quality bypass
capacitors are recommended for each power supply line in any
critical application. As shown in Figure 32, a 0.1 μF ceramic and
a 1 μF electrolytic capacitor placed as close as possible to the
amplifier (with short lead lengths to power supply common)
assures adequate high frequency bypassing in most applications.
A minimum bypass capacitance of 0.1 μF should be used for
any application.
