AD844JRZ-16

Product Summary

The AD844JRZ-16 is a high speed monolithic operational amplifier fabricated using Analog Device junction isolated complementary bipolar (CB) process. It combines high bandwidth and very fast large signal response with excellent dc performance. Although optimized for use in current-to-voltage applications and as an inverting mode amplifier, it is also suitable for use in many noninverting applications. The AD844JRZ-16 can be used in place of traditional op amps, but its current feedback architecture results in much better ac performance, high linearity, and an exceptionally clean pulse response. This type of op amp provides a closed-loop bandwidth that is determined primarily by the feedback resistor and is almost independent of the closed-loop gain. The AD844JRZ-16 is free from the slew rate limitations inherent in traditional op amps and other current-feedback op amps. Peak output rate of change can be over 2000 V/μs for a full 20 V output step. Settling time is typically 100 ns to 0.1%, and essentially independent of gain. The AD844JRZ-16 can drive 50Ω loads to ±2.5 V with low distortion and is short circuit protected to 80 mA. TheAD844JRZ-16 is available in four performance grades and three package options. In the 16-lead SOIC (R) package, the AD844JRZ-16 is specified for the commercial temperature range of 0°C to 70°C. The AD844JRZ-16 can be applied in flash adc input amplifiers, high speed current dac interfaces, video buffers and cable drivers, and pulse amplifiers.
