）》样章：LM1246 三通道前置视频放大器LM1246是一款新型的带宽为150MHz宽带视频放大器。

其具有许多优秀的功能，主要的有以下一些：内建增强型的I2C兼容微控制接口；ROM内含512个字符空间，RAM内含512个字符空间，4个8位的数模转换输出接口；屏显窗口具有淡入淡出功能和透明的半级灰度功能；无信号时的屏幕保护功能；供电电压跌落时，消除亮点功能；行场消隐；电源电压降至65%时转入安全模式。

LM1246常常和视放输出电路LM246X、偏置电路LM2479/80配合使用。

LM1246的后缀很多，不同的后缀代换容易导致屏显不正常，代换时需要注意。

工作电压范围：4.75V≤V CC≤5.25V。

DESCRIPTION
The DAC7552 is a 12-bit, dual-channel, voltage-output DAC with exceptional linearity and monotonicity. Its proprietary architecture minimizes undesired transients such as code-to-code glitch and channel-to-channel crosstalk. The low-power DAC7552 operates from a single 2.7-V to 5.5-V supply. The DAC7552 output amplifiers can drive a 2-kΩ, 200-pF load rail-to-rail with 5-µs settling time; the output range is set using an external voltage reference.
