DESCRIPTION
The MP204 is a high output current quad channel amplifier for driving the Ricoh GEN4 and GEN5 print heads. The MP204 utilizes ICs bined with discrete semiconductors and passive elements on a thermally conductive insulated metal substrate, delivering very high power from a pact module. The amplifier gain is fixed at 14V/V. Internal pensation provides optimum slew rate and insures stability. The only external ponents required are the current limit resistors RLIM, a series isolation resistor RS and power supply bypass capacitors.
