PRECISION OPERATIONAL AMPLIFIERS

Transcription

1 The is a precision, low drift operational amplifier providing the best features of existing T and ipolar op amps. Implementation of super gain transistors allows reduction of input bias currents by an order of magnitude over earlier devices such as the 308. Offset voltage and drift have also been reduced. lthough bandwidth and slew rate are not as great as T devices, input offset voltage, drift and bias current are inherently lower, particularly over temperature. Power consumption is also much lower, eliminating warm up stabilization time in critical applications. Offset balancing is provided, with the range determined by an external low resistance potentiometer. ompensation is provided internally, but external compensation can be added for improved stability when driving capacitive loads. The precision characteristics of the make this device ideal for applications such as charge integrators, analog memories, electrometers, active filters, light meters and logarithmic amplifiers. ow Input Offset oltage: 00 µ ow Input ias urrent: 7 p ow Input Offset urrent: 0.5 p ow Input Offset oltage rift:.0 µ/ ong Term tability: 0 µ/year igh ommon ode ejection: 30 d PIIO OPTIO PII IOTO TI T 8 IX PTI P 626 epresentative chematic iagram alance ompensation PI OTIO 3.0 p Q9 Q0 7.4 k 7.4 k 7.0 k 7.5 k Q7 Q8 alance Inputs alance Output 4 5 ompensation (Top iew) Q5 Q6 Q7 Q8 Q28.0 k Inputs + Q Q Q2 Q2 Q3 Q4 2.0 k 2.0 k Q3 Q4 6.2 k 80 k Q6 Q25.0 k Q5 30 p 2.0 k Q k.0 k Q20 Q2 Q24 20 k 50 k 362 Q22 Q23.2 k.4 k Q29 Q27 Q3 Q30 Q Output Q33 evice OI IOTIO Operating Temperature ange Package, T = 0 to +70 Plastic IP 2 24 OTOO O I I T

The inputs are shunted by back to back diodes for over voltage protection. xcessive current will flow if the input differential voltage is in excess of.0 if no limiting resistance is used. dditionally, a 2.0 kω resistance in each input is suggested to prevent possible latch up initiated by supply reversals. 2. The output is current limited when shorted to ground or any voltages less than the supplies. ontinuous overloads will require package dissipation to be considered and heatsinking should be provided when necessary. 3. evices must be derated based on package thermal resistance (see package outline dimensions). 4.

The potential problem involves reversal of one supply which can cause excessive current to flow in the second supply. Possible destruction of the I could result if the second supply is not current limited to approximately 00 m or if bypass capacitors greater than.0 µ are used in the supply bus. isconnecting one supply will generally cause reversal due to loading of the other supply within the I and in external circuitry. lthough the problem can usually be avoided by placing clamp diodes across the power supplies of each printed circuit board, a careful design will include sufficient resistance in the input leads to limit the current to 0 m if the input leads are pulled to either supply by internal currents. This precaution is not limited only to the. The is capable of resolving picoampere level signals. eakage currents external to the I can severely impair the performance of the device. It is important that high quality insulating materials such as teflon be employed. Proper cleaning to remove fluxes and other residues from printed circuit boards, sockets and the device package are necessary to minimize surface leakage. When operating in high humidity environments or temperatures near 0, a surface coating is suggested to set up a moisture barrier. eakage effects on printed circuit boards can be reduced by encircling the inputs (both sides of pc board) with a conductive guard ring connected to a low impedance potential nearly the same as that of the inputs. uard ring electrical connections for common operational amplifier configurations are illustrated in igure 4. lectrostatic shielding is suggested in high impedance circuits. rror voltages in external circuitry can be generated by thermocouple effects. issimilar metals along with temperature gradients can set up an error voltage ranging in the hundreds of microvolts. ome of the best thermocouples are junctions of dissimilar metals made up of I package pins and printed circuit boards. Problems can be avoided by keeping low level circuitry away from heat generating elements. The is internally compensated, but external compensation can be added to improve stability, particularly when driving capacitive loads. igure 4. uard ing lectrical onnections for ommon mplifier onfigurations Input umming mp (Inverting) 2 oninverting 2 oltage ollower Output Input Output Input Output OTOO O I I T

The packaging availability for each device type is indicated on the individual data sheets and the elector uide. ll of the outline dimensions for the packages are given in this section. The maximum power consumption an integrated circuit can tolerate at a given operating ambient temperature can be found from the equation: T(max) T P(T) = θ(typ) where: P(T) = Power issipation allowable at a given operating ambient temperature. This must be greater than the sum of the products of the supply voltages and supply currents at the worst case operating condition.
