MSK0032

MIL-PRF-38534 CERTIFIED HIGH SPEED, FET INPUT DIFFERENTIAL OP-AMP M.S.KENNEDY CORP. 4707 Dey Road Liverpool, N.Y. 13088 0032 (315) 701-6751 FEATURES: Fast Slew Rate - 650 V/µS Typ. FET Input Wide Bandwidth Electrically Isolated Case Industry Wide Pin Compatible 0032 Upgrade DSCC SMD 5962-80013 DESCRIPTION: The MSK 0032 is a high speed, FET input, differential amplifier designed to replace the popular LH0032 and TP0032. Since the MSK 0032 requires less compensation than the LH0032, it exhibits wider bandwidth and greater stability. The MSK 0032 can be used as a direct replacement in current designs using the LH0032 or TP0032 with no changes to compensation schemes. High frequency signal transfer circuits such as video amplifiers, high speed integrators and comparators are just a few of the applications that the MSK 0032 is well suited for.

C 9/06 APPLICATION NOTES HEAT SINKING Since the case of the MSK 0032 only runs approximately 40°C hotter than the ambient temperature, a heat sink is generally not necessary. However, in applications where it is critical to minimize input bias current, a heat sink may be used.The case of the MSK 0032 is isolated from the internal circuitry so the heat sink may be attached directly to the case. The heat sink may however create enough parasitic capacitance at the pins to necessitate adjusting the amount of compensation used. COMPENSATION When replacing an LH0032 or TP0032 with an MSK 0032, no changes in compensation need be made. The MSK 0032 will demonstrate greater loop stability than the LH0032 and loop stability very similar to the TP0032. As with any operational amplifier, a feedback capacitor in the range of 2-10pF is recommended to compensate for the effect of the R-C time constant created by the input capacitance of the op-amp and the feedback and input resistors in an inverting configuration. See Figure 3 and Figure 4 for recommended compensation schemes for non-inverting configurations. INPUT OFFSET VOLTAGE NULL Figure 3 Figure 1 The input offset voltage of the MSK 0032 is typically less than ±0.5mV. If it is necessary to null the offset to zero or some value other than zero, the above circuit is recommended. Typical offset adjust range is 25mV. Figure 4 POWER SUPPLY BYPASSING Both the negative and the positive power supplies must be effectively decoupled with a high and low frequency bypass circuit to avoid power supply induced oscillation. An effective decoupling scheme consists of a 0.1 microfarad ceramic capacitor in parallel with a 4.7 microfarad tantalum capacitor from each power supply pin to ground. 3 Rev.
