Description:

The RM733/RC733 integrated circuit is a monolithic video amplifier with differential inputs and differential outputs. lt offers three selectable voltage gains of 10, 100, or 400 and adjustable gain of 10 to 400 using a single resistor. No external frequency compensation is necessary for any gain option. The circuit and process designs are optimized to give a stable gain wide bandwidth (DC to 120MHz), high input resistance (250KΩ), and Iovv phase shift that is linear up to 10MHz (20 per MHz). The RM733/RC733 is designed for use as a read head amplifier for magnetic tape, drum, or disc memories using phase of NRZ encoding. It will also function as a preamplifier for high speed film or plated wire memory systems; as a video or pulse amplifier, pulse height detector, peak detector. Applications for the RM733/RC733 include bulk computer memory systems, very high speed random access memor systems, communications systems, nuclear event instrumentation, frequency counters, and other systems vvhere the specific design features of the RM733/RC733 are required. The RM733 video amplifier wiil operate over the complete military temperature range from -55°C to +125°C while the commercial version, the RC733, operates from 0°C to +70°C.

The features of RM733/RC733 can be summarized as (1)wide bandwidth DC to 120MHz; (2)low linear phase shift 2r/MHz to 10MHz; (3)setectable voltage gains 10, 100, or 400; (4)excellent pulse characteristics; (5)high input resistance 250kΩ.

The absolute maximum ratings of RM733/RC733 are (1)supply voltage: ±80V; (2)operating temperature range RM733 -55°C to +125°C, RC733 0°C to +70°C; (3)differential input voltage ±50V ; (4)common mode input voltage ±60V; (5)input current: 10mA; (6)storage temperature range: -65°C to +150°C; (7)internal power disslpation metal can: 500mW; (8)lead temperature (soldering, 60s):300°C; (9)flat pack: 570mW.
