APPLICATIONS Line Drivers DAC and ADC Buffers Video and Pulse Amplifiers Available in Plastic DIP, Hermetic Metal Can, Hermetic Cerdip, SOIC and LCC Packages and in Chip Form MIL-STD-883B Parts Available Available in Tape and Reel in Accordance with EIA-481A Standard PRODUCT DESCRIPTION The AD842 is a member of the Analog Devices family of wide bandwidth operational amplifiers. This device is 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 80 MHz gain bandwidth, the AD842 offers extremely fast settling characteristics, typically settling to within 0.01% of final value in less than 100 ns for a 10 volt step. The AD842 also offers a low quiescent current of 13 mA, a high output current drive capability (100 mA minimum), a low input voltage noise of 9 nV√Hz and a low input offset voltage (1 mV maximum). The 375 V/µs slew rate of the AD842, along with its 80 MHz gain bandwidth, ensures excellent performance in video and pulse amplifier applications. This amplifier is ideally suited for use in high frequency signal conditioning circuits and wide bandwidth active filters. The extremely rapid settling time of the AD842 makes this amplifier the preferred choice for data acquisition applications which require 12-bit accuracy.

APPLICATION HIGHLIGHTS 1. The high slew rate and fast settling time of the AD842 make it ideal for DAC and ADC buffers amplifiers, lines drivers and all types of video instrumentation circuitry. 2. The AD842 is a precision amplifier. It offers accuracy to 0.01% or better and wide bandwidth; performance previously available only in hybrids. 3. Laser-wafer trimming reduces the input offset voltage of 1 mV max, thus eliminating the need for external offset nulling in many applications. 4. Full differential inputs provide outstanding performance in all standard high frequency op amp applications where the circuit gain will be 2 or greater. 5.

E AD842 OFFSET NULLING The input offset voltage of the AD842 is very low for a high speed op amp, but if additional nulling is required, the circuit shown in Figure 21 can be used. ERROR AMP (ⴛ15) TEK 7A13 TEK 7603 OSCILLOSCOPE AD842 SETTLING TIME TEK 7A16 Figures 22 and 24 show the settling performance of the AD842 in the test circuit shown in Figure 23. HP6263 DDD5109 FLAT-TOP PULSE GENERATOR Settling time is defined as: The interval of time from the application of an ideal step function input until the closed-loop amplifier output has entered and remains within a specified error band. 499⍀ 1k⍀ 499⍀ 1k⍀ 0.1F 50⍀ +15V 2.2F This definition encompasses the major components which comprise settling time. They include (1) propagation delay through the amplifier; (2) slewing time to approach the final output value; (3) the time of recovery from the overload associated with slewing and (4) linear settling to within the specified error band. 0.1F 2.2F –15V Figure 23. Settling Time Test Circuit Figure 23 shows how measurement of the AD842’s 0.01% settling in 100 ns was accomplished by amplifying the error signal from a false summing junction with a very high-speed proprietary hybrid error amplifier specially designed to enable testing of small settling errors. The device under test was driving a 300 Ω load. The input to the error amp is clamped in order to avoid possible problems associated with the overdrive recovery of the oscilloscope input amplifier. The error amp gains the error from the false summing junction by 15, and it contains a gain vernier to fine trim the gain. 0.1F 2.2F INPUT – AD842 + OUTPUT 0.1F RL 2.2F –VS Figure 24 shows the “long term” stability of the settling characteristics of the AD842 output after a 10 V step. There is no evidence of settling tails after the initial transient recovery time. The use of a junction isolated process, together with careful layout, avoids these problems by minimizing the effects of transistor isolation capacitance discharge and thermally induced shifts in circuit operating points. These problems do not occur even under high output current conditions. Figure 21. Offset Nulling (DIP Pinout) Figure 22. 0.01% Settling Time REV. E Powered by ICminer.com Electronic-Library Service CopyRight 2003 499⍀ 499⍀ Expressed in these terms, the measurement of settling time is obviously a challenge and needs to be done accurately to assure the user that the amplifier is worth consideration for the application. +VS 10k⍀ FET PROBE TEK P6201 AD842 –7– AD842 GROUNDING AND BYPASSING USING A HEAT SINK In designing practical circuits with the AD842, the user must remember that whenever high frequencies are involved, some The AD842 draws less quiescent power than most precision high speed amplifiers and is specified for operation without a heat sink. However, when driving low impedance loads, the current to the load can be 10 times the quiescent current. This will create a noticeable temperature rise. Improved performance can be achieved by using a small heat sink such as the Aavid Engineering #602B. TERMINATED LINE DRIVER The AD842 is optimized for high speed line driver applications. Figure 25 shows the AD842 driving a doubly terminated cable in a gain-of-2 follower configuration. The AD842 maintains a typical slew rate of 375 V/µs, which means it can drive a ± 10 V, 6.0 MHz signal or a ± 3 V, 19.9 MHz signal. The termination resistor, RT, (when equal to the characteristic impedance of the cable) minimizes reflections from the far end of the cable. A back-termination resistor (RBT, also equal to the characteristic impedance of the cable) may be placed between the AD842 output and the cable in order to damp any stray signals caused by a mismatch between RT and the cable’s characteristic impedance. This will result in a “cleaner” signal. With this circuit, the voltage on the line equals VIN because one half of VOUT is dropped across RBT. Figure 24. AD842 Settling Demonstrating No Settling Tails special precautions are in order. Circuits must be built with short interconnect leads. Large ground planes should be used whenever possible to provide a low resistance, low inductance circuit path, as well as minimizing the effects of high frequency coupling. Sockets should be avoided because the increased interlead capacitance can degrade bandwidth. Feedback resistors should be of low enough value to assure that the time constant formed with the circuit capacitances will not limit the amplifier performance. Resistor values of less than 5 kΩ are recommended. If a larger resistor must be used, a small (<10 pF) feedback capacitor connected in parallel with the feedback resistor, RF, may be used to compensate for these stray capacitances and optimize the dynamic performance of the amplifier in the particular application. Power supply leads should be bypassed to ground as close as possible to the amplifier pins. A 2.2 µF capacitor in parallel with a 0.1 µF ceramic disk capacitor is recommended. The AD842 has ± 100 mA minimum output current and, therefore, can drive ± 5 V into a 50 Ω cable. The feedback resistors, R1 and R2, must be chosen carefully. Large value resistors are desirable in order to limit the amount of current drawn from the amplifier output. But large resistors can cause amplifier instability because the parallel resistance R1储R2 combines with the input capacitance (typically 2–5 pF) to create an additional pole. Also, the voltage noise of the AD842 is equivalent to a 5 kΩ resistor, so large resistors can significantly increase the system noise. Resistor values of 1 kΩ or 2 kΩ are recommended. If termination is not used, cables appear as capacitive loads and can be decoupled from the AD842 by a resistor in series with the output. CAPACITIVE LOAD DRIVING ABILITY Like all wideband amplifiers, the AD842 is sensitive to capacitive loading. The AD842 is designed to drive capacitive loads of up to 20 pF without degradation of its rated performance. Capacitive loads of greater than 20 pF will decrease the dynamic performance of the part although instability should not occur unless the load exceeds 100 pF. 2.2F +VS 0.1F VIN + RST AD842 TERMINATION RESISTOR FOR INPUT SIGNAL – 50⍀ OR 75⍀ CABLE 0.1F –VS 2.2F RT R1 RT = RST = CABLE CHARACTERISTIC IMPEDANCE R2 Figure 25.
