APEX MP204
The MP204 is a high output current quad channel amplifier for driving the Ricoh GEN4 and GEN5 print heads. The MP204 utilizes ICs combined with discrete semiconductors and passive elements on a thermally conductive insulated metal substrate, delivering very high power from a compact module. The amplifier gain is fixed at 14V/V.| Part No. | MP204 |

FEATURES
● 4 Channel Power Amplifier for Ricoh GEN4/GEN5 Print Heads● Operate from Single High Current Supply
● 7.5A Pulsed Current (C=320nF, R=0.1 Ω @ 15 V/μsec)
● 1.5A Continuous Current
● Programmable Current Limit
APPLICATIONS
● Ricoh GEN4 and GEN5 Print HeadsDESCRIPTION
The amplifier gain is fixed at 14V/V. Internal compensation provides optimum slew rate and insures stability. The only external components required are the current limit resistors RLIM, a series isolation resistor RS and power supply bypass capacitors.
