Hybrid Operational Amplifier

we have generally confined our discussions and design examples to the basic 741 and the MC741SC. These devices are certainly not the newest, fastest, or necessarily the best in all applications, but they are very common and the principles presented directly extend to other higher-performance devices. To provide the reader with a dramatic performance contrast, and to illustrate the performance characteristics that are available in op amps, we will briefly examine the operational characteristics of a hybrid op amp manufactured by the M.S. Kennedy Corporation (MSK). Numerous devices manufactured by MSK offer outstanding performance. We will describe the MSK 739 Wideband Amplifier as a representative device.




The MSK 739 is manufactured using hybrid {i.e., both thick-film and thinfilm) technology. It is not appropriate for general-purpose applications any more than the standard 741 is appropriate for very-high-performance applications.
Nevertheless, its performance can be quickly appreciated by contrasting some of
its key parameters with those of a general-purpose amplifier. Table 11.1 provides
comparative data.
The data in the table is intended for comparison purposes only to illustrate
some of the outstanding performance that is available in hybrid op amps. The
characteristics cited for the general-purpose device are typical and do not necessarily
represent a specific device.

FEATURES:

• Very Fast Setting Time - 10nS to 0.1% Typical
• Very Fast Slew Rate - 5500 V/μS Typical
• Unity Gain Bandwidth - 220 MHz Typical
• Low Noise - 0.15uVrms Typical (f=0.1Hz to 10Hz)
• Very Accurate (Low Offset) ±75μV Max.
• Pin Compatable with AD9610
• Contact MSK for MIL-PRF-38534 Qualification Status
• MIL-PRF-38534 CERTIFIED

The MSK 739 is an inverting composite operational amplifier that combines extremely high bandwidth and slew rate with
excellent D.C. accuracy to produce an amplifier perfectly suited for high performance data aquisition and conversion as well
as high speed commmunication and line drive. The performance of the MSK 739 is guaranteed over the full military temperature
range and for more cost sensitive applications is available in an industrial version. The standard package style is a
space efficient 12 pin TO-8. However, alternate package styles are available upon request.
