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 The combination of excellent noise performance and low input in the warmed-up condition. Analog Devices’ laser wafer current also make the AD711 useful for photo diode preamps. drift trimming process reduces input offset voltage drifts to Common-mode rejection of 88 dB and open loop gain of 3 mV/∞C max on the AD711C. 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 The AD711 is pinned out in a standard op amp configuration has a 100% tested minimum slew rate of 16 V/ms. Thus this and is available in seven performance grades. The AD711J and device is ideal for applications such as DAC and ADC AD711K are rated over the commercial temperature range of buffers which require a combination of superior ac and dc 0∞C to 70∞C. The AD711A, AD711B and AD711C are rated performance. over the industrial temperature range of –40∞C to +85∞C. 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 –40∞C to +125∞C and are available processed to MIL- STD-883B, REV. E. 5. Analog Devices’ well-matched, ion-implanted JFETs ensure 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.
