AD841JNZ

The AD841JNZ is a member of the Analog Devices, Inc., family of wide bandwidth operational amplifiers. This high speed/high precision family includes the AD842, which is stable at a gain of two or greater and has 100 mA minimum output current drive. These devices are fabricated using Analog Devices’ junction isolated complementary bipolar (CB) process. This process permits a combination of dc precision and wideband ac performance previously unobtainable in a monolithic op amp. In addition to its 40 MHz unity-gain bandwidth product, the AD841JNZ offers extremely fast settling characteristics, typically settling to within 0.01% of final value in 110 ns for a 10 V step.

Unlike many high frequency amplifiers, the AD841JNZ requires no external compensation. It remains stable over its full operating temperature range. It also offers a low quiescent current of 12 mA maximum, a minimum output current drive capability of 50 mA, a low input voltage noise of 15 nV/√Hz, and low input offset voltage of 1 mV maximum.

The 300 V/µs slew rate of the AD841, along with its 40 MHz gain bandwidth, ensures excellent performance in video and pulse amplifier applications. This amplifier is well suited foruse in high frequency signal conditioning circuits and wide bandwidth active filters. The extremely rapid settling time of the AD841JNZ makes it the preferred choice for data acquisition applications that require 12-bit accuracy. The AD841JNZ is also appropriate for other applications such as high speed DAC and ADC buffer amplifiers and other wide bandwidth circuitry.
