* EL4332C Macromodel * Revision A, April 1996 ******************************************************************************* ** * Applications Hints. The EL 4332 has two Vcc pins, one Vee pin, and three *ground pins. The Vcc pins * (pins 14 and 15 are internally shorted *together in the model, but the ground pins (GND1, GND2, and * GND3 (nodes 2, 7, and 10, respectively) must be connected to ground (node 0) using a *1e-6 ohm resistor. * Alternatively, nodes 2, 7, and 10 may be connected to ground through a 25 *ohm resistor in parallel with a 4 nH inductor to simulate package and PCB *parasitics. * ****************************************************************************** * Connections: * OUT1 * | GND1 * | | A1 * | | | B1 * | | | | B2 * | | | | | A2 *. | | | | | | GND2 * | | | | | | | OUT2 * | | | | | | | | * | | | | | | | | * 1 2 3 4 5 6 7 8 * * OUT3 * | GND3 * | | B3 * | | | A3 * | | | | Vee * | | | | | Vcc * | | | | | | Vcc * | | | | | | | A/B * | | | | | | | | * | | | | | | | | * 9 10 11 12 13 14 15 16 * * .subckt el4332C 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ****************** A B Switch *********************************** Rshort 14 15 1e-12 rshort1 15 0 1000Meg Isw 14 110 1.5mA vref 111 0 1.6v q1 101 16 110 qp q2 102 111 110 qp R1 101 13 500 R2 102 13 500 Rd1 107 0 100 Esw 107 0 table {v(102,101)*100} (0,0) (1,1) * *************** Amplifier #1 ***************** q131 103 3 112 qp q141 104 114 113 qp q151 105 4 115 qp q161 106 117 116 qp Ia11 14 112 1mA Ia21 14 113 1mA Ib11 14 115 1mA Ib21 14 116 1mA Rga1 112 113 275 Rgb1 115 116 275 R31 103 13 275 R41 104 13 275 R51 105 13 275 R61 106 13 275 R71 1 114 400 R81 114 2 400 R91 1 117 400 R110 117 2 400 Ediff1 108 0 value {( v(104,103)*v(107)) + (v(106,105)*(1-v(107)))} rdiff1 108 0 1K * * Compensation Section * ga1 0 134 108 0 1m rh1 134 0 5Meg cc1 134 0 0.6pF * * Poles * ep1 141 0 134 0 1.0 rpa1 141 142 200 cpa1 142 0 0.75pF rpb1 142 143 200 cpb1 143 0 0.75pF * * Output Stage * i011 15 150 1.0mA i021 151 13 1.0mA q71 13 143 150 qp q81 15 143 151 qn q91 15 150 152 qn q101 13 151 153 qp ros11 152 1 2 ros21 153 1 2 * *************** Amplifier #2 ***************** q231 203 6 212 qp q241 204 214 213 qp q251 205 5 215 qp q261 206 217 216 qp Ia12 14 212 1mA Ia22 14 213 1mA Ib12 14 215 1mA Ib22 14 216 1mA Rga2 212 213 275 Rgb2 215 216 275 R231 203 13 275 R241 204 13 275 R251 205 13 275 R261 206 13 275 R271 8 214 400 R281 214 7 400 R291 8 217 400 R210 217 7 400 Ediff2 208 0 value {( v(204,203)*v(107)) + (v(206,205)*(1-v(107)))} rdiff2 208 0 1K * * Compensation Section * ga2 0 234 208 0 1m rh2 234 0 5Meg cc2 234 0 0.6pF * * Poles * ep2 241 0 234 0 1.0 rpa2 241 242 200 cpa2 242 0 0.75pF rpb2 242 243 200 cpb2 243 0 0.75pF * * Output Stage * i012 15 250 1.0mA i022 251 13 1.0mA q271 13 243 250 qp q281 15 243 251 qn q291 15 250 252 qn q201 13 251 253 qp ros12 252 8 2 ros22 253 8 2 * *************** Amplifier #3 ***************** q331 303 12 312 qp q341 304 314 313 qp q351 305 11 315 qp q361 306 317 316 qp Ia13 14 312 1mA Ia23 14 313 1mA Ib13 14 315 1mA Ib23 14 316 1mA Rga3 312 313 275 Rgb3 315 316 275 R331 303 13 275 R341 304 13 275 R351 305 13 275 R361 306 13 275 R371 9 314 400 R381 314 10 400 R391 9 317 400 R310 317 10 400 Ediff3 308 0 value {( v(304,303)*v(107)) + (v(306,305)*(1-v(107)))} rdiff3 308 0 1K * * Compensation Section * ga3 0 334 308 0 1m rh3 334 0 5Meg cc3 334 0 0.6pF * * Poles * ep3 341 0 334 0 1.0 rpa3 341 342 200 cpa3 342 0 0.75pF rpb3 342 343 200 cpb3 343 0 0.75pF * * Output Stage * i01 15 350 1.0mA i023 351 13 1.0mA q371 13 343 350 qp q381 15 343 351 qn q391 15 350 352 qn q301 13 351 353 qp ros13 352 9 2 ros23 353 9 2 * * Power Supply Current * ips 15 13 22mA * * Models * .model qp pnp(is=1.5e-16 bf=300 tf=0.01nS) .model qn npn(is=0.8e-18 bf=300 tf=0.01nS) .ends EL4332C *$
