GENERAL DESCRIPTION
The AD842 is a member of the Analog Devices, Inc. family of acquisition applications requiring 12-bit accuracy. The AD842 wide bandwidth operational amplifiers. This device is fabricated is also appropriate for other applications, such as high speed using the Analog Device junction isolated complementary DAC and ADC buffer amplifiers and other wide bandwidth bipolar (CB) process. This process permits a combination of dc circuitry. precision and wideband ac performance previously unobtain-
PRODUCT HIGHLIGHTS
able in a monolithic op amp. In addition to its 80 MHz gain bandwidth product, the AD842 offers extremely fast settling 1. The high slew rate and fast settling time of the AD842 characteristics, typically settling to within 0.01% of final value make it ideal for DAC and ADC buffers amplifiers, line in less than 100 ns for a 10 V step. drivers, and al types of video instrumentation circuitry. 2. The AD842 is a precision amplifier. It offers accuracy to The AD842 also offers a low quiescent current of 13 mA, a high 0.01% or better and wide bandwidth, performance output current drive capability (100 mA minimum), a low input previously available only in hybrids. voltage noise of 9 nV√Hz, and a low input offset voltage 3. Laser-wafer trimming reduces the input offset voltage of (1.5 mV maximum). 1.5 mV maximum, thus eliminating the need for external The 375 V/µs slew rate of the AD842, along with its 80 MHz offset nulling in many applications. gain bandwidth product, ensures excellent performance in 4. Full differential inputs provide outstanding performance in video and pulse amplifier applications. This amplifier is ideally al standard high frequency op amp applications where the suited for use in high frequency signal conditioning circuits and circuit gain is 2 or greater. wide bandwidth active filters. The extremely rapid settling time of the AD842 makes this amplifier the preferred choice for data
