MP2_MP22_MP2 HIGH SPEED, /-9V, RAIL-TO-RAIL INPUT-OUTPUT OP AMPS OPERATION DESCRIPTION The MP2/MP22/MP2 are high-speed, high slew rate, rail-to-rail input-output operational amplifiers. These devices can operate up to ma output current and 2MHz bandwidth. INPUT The MPX2 can operate with inputs from rail to rail. It does this through the use of two differential pairs. A traditional PNP differential pair is used from.v below the negative rail to V below the positive rail. At that point the input is switched to a NPN differential pair to operate up to.v above the positive rail. The transition from one input differential pair to the other can cause distortion. Inputs near the rails can also cause distortion and degradation of other specifications. OUTPUT Current Rating The MPX2 can sink or source ma. It can provide high values of peak current, and much reduced value of average current. When the output voltages are near the rails the ability to provide current will be reduced. Output Power Make sure that the rms power is such that the die junction temperature will remain below 2ºC. Power Requirements The MPx2 family operates from a voltage supply, of ±Vs and ground, or from a Vs split supply. Dual supply range is ±.6V to ±9.V. current changes suddenly. This can damage the part. Transients In addition to the ripple and noise on the power supplies, there are also transient voltage changes. This can be caused by another device on the same power supply suddenly drawing current or suddenly stopping a current draw. The design engineer should insure that there are no damaging transients induced on the power supply lines when the op amp suddenly changes current delivery. LAYOUT Ground Plane Connect the opamp to a ground plane rather than ground traces for very low impedance. If this is not possible then make the ground traces as fat and short as possible Decoupling High performance devices such as the MPX2, with high slew rates and high currents, need large decoupling capacitors. These should be placed as close to the supply pins as possible. Use ground and power planes to make these decoupling capacitors as effective as possible. If that is not realistic then make the ground and power traces as thick and short as possible. PSRR and Noise A common figure of merit is the PSRR (Power Supply Rejection Ratio). The PSRR is a measure of how much noise gets from the supply rails into the output. Notice that the PSRR falls with increasing frequency. In order to have good PSRR the ripple voltages and frequencies of the systems switching power supplies should be measured. If the PSRR is not acceptable, inductors can be inserted in series with the power supply rails to provide improved PSRR. Also make sure there are no transients created on the power supply lines when the MPX2 load MP2_MP22_MP2 Rev..9 www.monolithicpower.com 7 2/9/29 MPS Proprietary Information.
