accordance with the EIA-481A standard MIL-STD-883B parts available Single version available: AD711 Quad version: AD713 Available in PDIP, SOIC_N, and CERDIP packages GENERAL DESCRIPTION
The AD712 is a high speed, precision, monolithic operational Extended reliability PLUS screening is available, specified amplifier offering high performance at very modest prices. The over the commercial and industrial temperature ranges. PLUS very low offset voltage and offset voltage drift are the results of screening includes 168-hour burn-in, in addition to other advanced laser wafer trimming technology. These performance environmental and physical tests. benefits allow the user to easily upgrade existing designs that use older precision BiFETs and, in many cases, bipolar op amps. The AD712 is available in 8-lead PDIP, SOIC_N, and CERDIP packages. The superior ac and dc performance of this op amp makes it

suitable for active filter applications. With a slew rate of 16 V/μs and a settling time of 1 μs to ±0.01%, the AD712 is ideal as a 1. The AD712 offers excellent overall performance at very buffer for 12-bit digital-to-analog converters (DACs) and analog- competitive prices. to-digital converters (ADCs) and as a high speed integrator. 2. The Analog Devices, Inc., advanced processing technology The settling time is unmatched by any similar IC amplifier. and 100% testing guarantee a low input offset voltage (3 mV maximum, J grade). Input offset voltage is specified in the The combination of excellent noise performance and low input warmed-up condition. current also make the AD712 useful for photo diode preamps. 3. Together with precision dc performance, the AD712 offers Common-mode rejection of 88 dB and open-loop gain of excellent dynamic response. It settles to ±0.01% in 1 μs and 400 V/mV ensure 12-bit performance even in high speed has a minimum slew rate of 16 V/μs. Thus, this device is unity-gain buffer circuits. ideal for applications such as DAC and ADC buffers that The AD712 is pinned out in a standard op amp configuration require a combination of superior ac and dc performance. and is available in seven performance grades. The AD712J and AD712K are rated over the commercial temperature range of 0°C to 70°C. The AD712A is rated over the industrial tempera- ture range of −40°C to +85°C. The AD712S is rated over the military temperature range of −55°C to +125°C and is available processed to MIL-STD-883B, Rev. C.
