4707 Dey Road Liverpool, N.Y. 13088 M.S.KENNEDY CORP. (315) 701-6751 3554 FEATURES: Stable at Low Gain Fast Slew Rate - 1200V/µs Typical Gain Bandwidth Product - 1200 MHz Typical Low Quiescent Current - ±14.0 mA Typical Low Offset - 2 mV Maximum Drop In Replacement for OPA 3554 and TP 3554 High Output Current - ±100mA Minimum DESCRIPTION: The MSK 3554 is a pin compatible, low gain stable, drop-in replacement for the OPA 3554 and TP 3554. The MSK 3554 does not exhibit high frequency output oscillations like other versions of the 3554 when operated at closed loop gains of less than 55 V/V. The extremely low input bias current and input offset voltage ratings coupled with a high slew rate and wide bandwidth make the MSK 3554 an excellent choice for fast D/A converters, buffers, pulse amplifiers and other high speed op-amp applications. The MSK 3554 is packaged in an 8-pin TO-3 using thick film hybrid technology to obtain high reliability and compact size.

Refer to the following thermal model and governing equa- tions to determine appropriate heat sinking for your application. Example: This example demonstrates a worst case analysis for the op- amp output stage. This occurs when the output voltage is 1/2 the power supply voltage. Under this condition, maximum power transfer occurs and the output is under maximum stress. Conditions: VCC = ±16VDC VO = ±8Vp Sine Wave, Freq. = 1KHZ RL = 100Ω Governing Equation: TJ=PD x (RθJC + RθCS + RθSA) + TA Where TJ = Junction Temperature PD = Total Power Dissipation RθJC = Junction to Case Thermal Resistance RθCS = Case to Heat Sink Thermal Resistance RθSA = Heat Sink to Ambient Thermal Resistance TC = Case Temperature TA = Ambient Temperature TS = Sink Temperature For a worst case analysis we will treat the +8Vp sine wave as an 8 VDC output voltage. 1.) Find Driver Power Dissipation PD = (VCC-VO) (VO/RL) = .64W 2.) For conservative design, set TJ=+125°C 3.) For this example, worst case TA=+90°C 4.) RθJC = 37°C/W from MSK 3554B Data Sheet 5.) RθCS = 0.15°C/W for most thermal greases 6.) Rearrange governing equation to solve for RθSA RθSA = ((TJ - TA)/PD) - (RθJC) - (RθCS) = 54.7 - 37.15 = 17.54°C/W The heat sink in this example must have a thermal resistance of no more than 17.54°C/W to maintain a junction temperature of no more than +125°C. OFFSET NULL Typically, the MSK 3554(B) has an input offset voltage of less than ±0.5mV. If it is desirable to adjust the offset closer to "zero", or to a value other than "zero", the circuit below is recommended. Rp should be a ten-turn 20KΩ potentiometer. Typical offset adjust is ±20mV.

The effect of compensation ca- pacitance can be seen in the Bode Plot under the Typical Perfor- mance Curves. As closed loop gain increases, compensation capacitance can decrease and higher slew rates and wider band- widths will be realized. See the component selection table for recommended values of input and feedback resistance as well as feedback capacitance and compensation capacitance. Rev. B 7/00
