Its mental and physical tests. very low offset voltage and offset voltage drift are the results of advanced laser wafer trimming technology. These performance The AD711 is available in an 8-pin plastic mini-DIP, small benefits allow the user to easily upgrade existing designs that use outline, cerdip, TO-99 metal can, or in chip form. older precision BiFETs and, in many cases, bipolar op amps. PRODUCT HIGHLIGHTS The superior ac and dc performance of this op amp makes it 1. The AD711 offers excellent overall performance at very suitable for active filter applications. With a slew rate of 16 V/ms competitive prices. and a settling time of 1 ms to 0.01%, the AD711 is ideal as a buffer for 12-bit D/A and A/D Converters and as a high-speed 2. Analog Devices advanced processing technology and 100% integrator. The settling time is unmatched by any similar IC testing guarantee a low input offset voltage (0.25 mV max, amplifier. C grade, 2 mV max, J grade). Input offset voltage is specified in the warmed-up condition. Analog Devices laser wafer The combination of excellent noise performance and low input drift trimming process reduces input offset voltage drifts to current also make the AD711 useful for photo diode preamps. 3 mV/C max on the AD711C. Common-mode rejection of 88 dB and open loop gain of 400 V/mV ensure 12-bit performance even in high-speed unity 3. Along with precision dc performance, the AD711 offers gain buffer circuits. excellent dynamic response. It settles to 0.01% in 1 ms and has a 100% tested minimum slew rate of 16 V/ms. Thus this The AD711 is pinned out in a standard op amp configuration device is ideal for applications such as DAC and ADC and is available in seven performance grades. The AD711J and buffers which require a combination of superior ac and dc AD711K are rated over the commercial temperature range of performance. 0 C to 70 C. The AD711A, AD711B and AD711C are rated over the industrial temperature range of 40C to +85C. The 4. The AD711 has a guaranteed and tested maximum voltage AD711S and AD711T are rated over the military temperature noise of 4 mV p-p, 0.1 to 10 Hz (AD711C). range of 40C to +125 C and are available processed to MIL- 5. Analog Devices well-matched, ion-implanted JFETs ensure STD-883B, REV. E. a guaranteed input bias current (at either input) of 25 pA max (AD711C) and an input offset current of 10 pA max (AD711C). Both input bias current and input offset current are guaranteed in the warmed-up condition. REV. E Information furnished by Analog Devices is believed to be accurate and reliable.
