Manufacturer:CYPRESS Description:The LM2471 is a high voltage monolithic three channel CRT driver suitable for high resolution display applications. The LM2471 operates with 85V and 8V power supplies. The part is housed in the industry standard 11-lead TO-220 molded plastic power package. The circuit diagram of the LM2471 is shown in Figure 1. The PNP emitter follower, Q5, provides input buffering. Q1 and Q2 form a fixed gain cascode amplifier with resistors R1 and R2 setting the gain at −27. Emitter followers Q3 and Q4 isolate the high output impedance of the cascode stage from the capacitance of the CRT cathode which decreases the sensitivity of the device to load capacitance. Q6 provides biasing to the output emitter follower stage to reduce cross- over distortion at low signal levels. Figure 2 shows a typical test circuit for evaluation of the LM2471. This circuit is designed to allow testing of the LM2471 in a 50Ω environment without the use of an expen- sive FET probe. In this test circuit, the two 2.49kΩ resistors form a 200:1 wideband, low capacitance probe when con- nected to a 50Ω coaxial cable and a 50Ω load (such as a 50Ω oscilloscope input). The input signal from the generator is ac coupled to the base of Q5. |
