ADI AD712JRZ

The AD712 is a high-speed, precision, monolithic operational amplifier that offers high performance at a very reasonable price. Its extremely low offset voltage and offset voltage drift are the result of advanced laser wafer trimming technology. These performance advantages enable end-users to easily upgrade existing designs that use older precision BiFET and, in many cases, bipolar operational amplifiers. The outstanding AC and DC performance of this operational amplifier makes it suitable for active filter applications. With a slew rate of 16 V/μs and a 1 μs settling time of ±0.01%, the AD712 is well-suited for use as a buffer for 12-bit digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), as well as a high-speed integrator. This settling time is unmatched by any similar integrated circuit amplifier. The combination of excellent noise performance and low input current also makes the AD712 suitable for photodiode preamplifiers. A common-mode rejection of 88 dB and an open-loop gain of 400 V/mV ensure 12-bit performance even in high-speed unity-gain buffer circuits. The AD712 is pin-configured in a standard operational amplifier layout and is available in seven performance grades. The AD712J and AD712K are rated for the commercial temperature range of 0°C to 70°C. The AD712A is rated for the industrial temperature range of -40°C to +85°C. The AD712S is rated for the temperature range of -55°C to +125°C and can be processed to MIL-STD-883B, Rev. C. Extended reliability PLUS screening is available in the commercial and industrial temperature ranges. PLUS screening includes 168 hours of burn-in, as well as other environmental and physical tests. The AD712 is available in 8-pin PDIP, SOIC_N, and CERDIP packages.
