The load circuit appears resistive to the MP39. �� DESCRIPTION The MP39 is a cost-effective high voltage MOSFET power operational ampliﬁer constructed with surface mount components on a thermally conductive but electrically isolated substrate. While the cost is low the MP39 offers many of the same features and performance speciﬁcations found in much more expensive hybrid power ampliﬁers. The metal substrate allows the MP39 to dissipate power up to 125 watts and its power supply voltages can range up to +/- 50 Volts (100V total). Optional boost voltage inputs allow the small signal portion of the ampliﬁer to operate at higher supply voltages than the high current output stage. The ampliﬁer is then biased to achieve close linear swings to the supply rails at high current for extra efﬁcient operation. External compensation tailors performance to the user needs. A four-wire sense technique allows current limiting without the need to consider internal or external mili-ohm parasitic resistance in the output line. An Iq pin is available which can be used to shut off the quiescent current in the output stage. The output stage then operates class C and lowers quiescent power dissipation. This is useful in applications where output crossover distortion is not important. �� EXTERNAL CONNECTIONS � �� EQUIVALENT SCHEMATIC �� * SEE "BYPASSING" PARAGRAPH Phase Compensation Gain Cc Rc 1 470pF 100Ω ≥3 220pF Short ≥ 10 100pF Short APEX MICROTECHNOLOGY CORPORATION • TELEPHONE (520) 690-8600 • FAX (520) 888-3329 • ORDERS (520) 690-8601 • EMAIL prodlit@apexmicrotech.com �� 1 ABSOLUTE MAXIMUM RATINGS SPECIFICATIONS MP39 • MP39A SUPPLY VOLTAGE, +VS to –VS BOOST VOLTAGE OUTPUT CURRENT, within SOA POWER DISSIPATION, internal INPUT VOLTAGE, differential INPUT VOLTAGE, common mode TEMPERATURE, pin solder - 10s TEMPERATURE, junction2 TEMPERATURE, storage OPERATING TEMPERATURE RANGE, case MP39 TYP 5 30 15 30 10 .01 10 1010 20 ±VB 12 98 10 113 2 40 60 ±VS 8.8 ±VS 6.0 ±VS 6.8 ±VS 1.1 2.5 10 10 4 ± ± ± ± * * * * 10 ±50 22 26 .9 1.2 85 * * ± 100V ±VS ±20V 25A 125W ±20V ±VB 200°C 175°C –40 to +105°C –40 to +85°C MP39A TYP * * * * * * * * * * * * * * * * * * * * ABSOLUTE MAXIMUM RATINGS SPECIFICATIONS PARAMETER INPUT OFFSET VOLTAGE, initial OFFSET VOLTAGE, vs. temperature OFFSET VOLTAGE, vs. supply OFFSET VOLTAGE, vs. power BIAS CURRENT, initial BIAS CURRENT, vs. supply OFFSET CURRENT, initial INPUT IMPEDANCE, DC INPUT CAPACITANCE COMMON MODE VOLTAGE RANGE COMMON MODE REJECTION, DC INPUT NOISE GAIN OPEN LOOP, @15Hz GAIN BANDWIDTH PRODUCT POWER BANDWIDTH PHASE MARGIN OUTPUT VOLTAGE SWING VOLTAGE SWING SETTLING TIME to .1% SLEW RATE CAPACITIVE LOAD RESISTANCE CURRENT, CONTINUOUS POWER SUPPLY VOLTAGE CURRENT, quiescent, boost supply CURRENT, quiescent, total THERMAL RESISTANCE, AC, junction to case3 RESISTANCE, DC, junction to case RESISTANCE4, junction to air TEMPERATURE RANGE, case TEST CONDITIONS 1 MIN MAX 10 50 200 50 * * MIN MAX 3 * 100 30 UNITS mV µV/°C µV/V µV/W pA pA/V pA Ω pF V dB µVrms db MHz kHz ° V V µs V/µs nF Ω A V mA mA °C/W °C/W °C/W °C Full temperature range Full temperature range Full temperature range, CC = 100pF IO=10A RL=10Ω, VO = 90V p-p CC = 100pF Full temperature range IO=10A ±VB = ±VS ±10V, IO=10A AV=+1,10V step, RL =4Ω AV= –10, CC= 100pF Full temperature range, AV=+1 94 Full temperature range ±15 Full temperature range, F>60Hz Full temperature range, F
