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 it 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’s 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 offered in a 16-pin SOIC, 14-pin plastic DIP and hermetic cerdip package, or in chip form. 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, A and S Grades). 3. The combination of Analog Devices’ 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.

The AD713 is internally compensated for stable operation at unity gain and is available in seven performance grades. The AD713J and AD713K are rated over the commercial temperature range of 0°C to +70°C. The AD713A and AD713B are rated over the industrial temperature of –40°C to +85°C. The AD713S and AD713T are rated over the military temperature range of –55°C to +125°C and are available processed to MIL-STD-883B, Rev. C.
