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.
Slew rate is 100% tested for a guaranteed minimum of
16 V/μs (J and A grades).
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.
Very close matching of ac characteristics between the four
amplifiers makes the AD713 ideal for high quality active
filter applications.
