PRODUCT HIGHLIGHTS PRODUCT DESCRIPTION
1. The AD746 offers exceptional dynamic response for high The AD746 is a dual operational amplifier, consisting of two speed data acquisition systems. It settles to 0.01% in 500 ns AD744 BiFET op amps on a single chip. These precision and has a 100% tested minimum slew rate of 50 V/µs monolithic op amps offer excellent dc characteristics plus rapid (AD746B). settling times, high slew rates and ample bandwidths. In 2. Outstanding dc precision is provided by a combination of addition, the AD746 provides the close matching ac and dc Analog Devices’ advanced processing technology, laser wafer characteristics inherent to amplifiers sharing the same drift trimming and well-matched ion-implanted JFETs. Input monolithic die. offset voltage, input bias current and input offset current are The single pole response of the AD746 provides fast settling: specified in the warmed-up condition and are 100% tested. 500 ns to 0.01%. This feature, combined with its high dc 3. Differential and multichannel systems will benefit from the precision, makes it suitable for use as a buffer amplifier for 12- AD746’s very close matching of ac characteristics. Input or 14-bit DACs and ADCs. Furthermore, the AD746’s low total offset voltage specs are fully tested and guaranteed to a harmonic distortion (THD) level of 0.0001% and very close maximum of 0.5 mV (AD746B). matching ac characteristics make it an ideal amplifier for many 4. The AD746 has very close, guaranteed matching of input demanding audio applications. bias current between its two amplifiers. The AD746 is internally compensated for stable operation as a 5. Unity gain stable version AD712 also available. unity gain inverter or as a noninverting amplifier with a gain of 2 or greater. It is available in four performance grades. The AD746J is rated over the commercial temperature range of 0 to +70°C. The AD746A and AD746B are rated over the industrial temperature range of –40°C to +85°C. The AD746S is rated over the military temperature range of –55°C to +125°C and is available processed to MIL-STD-883B, Rev. C. REV.
