MAX445CPG中文资料美信数据手册PDF规格书

General Description

The MAX445 is a high-performance, monolithic, variable gain transconductance amplifier with a high-voltage open-collector output capable of directly driving a video display (CRT cathode). A 2.5ns rise time is achieved using a peaking network with a 200Ω load resistor and an 8pF total load (CRT and parasitic capacitance).

特性 Features

♦ 2.5ns Rise/Fall Time into an 8pF Load

♦ 200MHz Small-Signal Bandwidth

♦ 50Vp-p Output

♦ Ground Referenced Differential Inputs

♦ Linear Variable Gain for Contrast Control

♦ Offset Adjustment for Black Level

♦ 5.5V Bandgap Reference

♦ Drives 1280 x 1024 and 1530 x 1280 Displays

Applications
