* MAX4012 MACROMODEL * ------------------------------ * Revision 0, 10/007 * ------------------------------ * MAX4012 are op amps with unity gain stable devices that combine high speed performance with rail to rail outputs. * These devices require only 5.5mA of quiscent supply current while achieving 200Mhz 3db bandwidth and 600V/us slewrate. * ------------------------------ * Macro model is developed using the typical device parameters given in the data sheet with * 5 volts power supply. Model does not take care of the device non-linearity with supply voltage * variations and temperature variations. Model characteristics may not match actual device behavior * at abnormal operating conditions. * ------------------------------ * Parameters which are not modeled: * Enable and its related parameters * Noise and Hormonic distortion * Open loop output resistance * Input capacitance * Settling time * Differential gain and phase error * ------------------------------ * Connections * 1 = OUT * 2 = Vee * 3 = IN+ * 4 = IN- * 5 = VCC **************** .subckt MAX4012 1 2 3 4 5 R_MAX4012_R5 1 2 0.8k I_MAX4012_I2 MAX4012_N251313 MAX4012_N251287 DC 1.04Adc M_MAX4012_M2 MAX4012_N245605 4 MAX4012_N245683 MAX4012_N245605 + NMOS w=2u l=1u R_MAX4012_R9 3 2 3000K D_MAX4012_D6 MAX4012_N247809 MAX4012_N251313 diodemacro_ideal R_MAX4012_R7 MAX4012_N247765 1 0.8k V_MAX4012_V5 MAX4012_N247765 MAX4012_N2489971 0.06Vdc E_MAX4012_E2 MAX4012_N249601 2 MAX4012_N245605 MAX4012_N248757 10000 D_MAX4012_D7 MAX4012_N251287 MAX4012_N247809 diodemacro_ideal C_MAX4012_C3 MAX4012_N245683 MAX4012_N245687 .24p R_MAX4012_R1 MAX4012_N245687 MAX4012_N247765 2.5k V_MAX4012_V9 MAX4012_N247871 2 -0.2Vdc G_MAX4012_G5 MAX4012_N247809 2 MAX4012_N247765 2 -1.593E-3 D_MAX4012_D8 MAX4012_N248333 MAX4012_N251313 diodemacro_ideal D_MAX4012_D4 MAX4012_N2483210 1 diodemacro_ideal R_MAX4012_R2 MAX4012_N247765 MAX4012_N245683 2.5k G_MAX4012_G4 MAX4012_N247809 2 MAX4012_N245605 2 -1.15E-5 V_MAX4012_V10 MAX4012_N2483210 2 0.06Vdc V_MAX4012_V8 MAX4012_N248757 5 -4.75Vdc D_MAX4012_D9 MAX4012_N251287 MAX4012_N248333 diodemacro_ideal G_MAX4012_G2 MAX4012_N247765 1 MAX4012_N248333 1 .0195 G_MAX4012_G3 1 2 MAX4012_N248333 1 -.0195 M_MAX4012_M3 MAX4012_N247809 MAX4012_N249601 2 2 NJNT w=20u l=1u C_MAX4012_C2 2 MAX4012_N248333 1310p G_MAX4012_G1 MAX4012_N247809 2 MAX4012_N245687 MAX4012_N245683 1.15 D_MAX4012_D3 MAX4012_N247871 MAX4012_N247809 diodemacro_ideal I_MAX4012_I4 4 2 DC 4.63uAdc V_MAX4012_V7 3 MAX4012_N2455571 11mdc R_MAX4012_R3 2 MAX4012_N247809 1K R_MAX4012_R10 4 2 3000K R_MAX4012_R8 3 4 140k I_MAX4012_I5 3 2 DC 4.6uAdc D_MAX4012_D5 MAX4012_N248961 MAX4012_N245605 diodemacro_ideal I_MAX4012_I1 MAX4012_N245605 2 DC 800uAdc D_MAX4012_D12 MAX4012_N247809 MAX4012_N2477051 diodemacro_ideal I_MAX4012_I7 5 2 DC 5.5mAdc E_MAX4012_E1 MAX4012_N247765 2 5 2 1 V_MAX4012_V11 MAX4012_N2477051 MAX4012_N247765 0.2Vdc M_MAX4012_M1 MAX4012_N245687 MAX4012_N2455571 MAX4012_N245605 + MAX4012_N245605 NMOS w=2u l=1u V_MAX4012_V6 MAX4012_N248961 2 -10Vdc D_MAX4012_D11 1 MAX4012_N2489971 diodemacro_ideal ************************* .model diodemacro_ideal d(n=0.001) .model NMOS nmos(VTO=0.5 KP=100E-6) .model NJNT nmos(VTO=0.5 KP=50E-6) .ends MAX4012 * Copyright (c) 2003-2012 Maxim Integrated Products.
