TC7126CKW集成电路（IC）的显示驱动器规格书PDF中文资料

TC7126CKW属于集成电路（IC）的显示驱动器。由微芯科技股份有限公司制造生产的TC7126CKW显示驱动器显示驱动器是一种集成电路 (IC)，可在微处理器 (MPU)、微控制器 (MCU) 或其他电路系统之间提供转换、接口和控制，用于 LCD、LED、OLED、DLP、真空荧光和 AMOLED 等显示器。可能的通信接口和协议包括模拟、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

General Description:

The TC7126A is a 3-1/2 digit CMOS Analog-to-Digital Converter (ADC) containing all the active components necessary to construct a 0.05 resolution measure ment system. Seven-segment decoders, digit and polarity drivers, voltage reference, and clock circuit are integrated on-chip. The TC7126A directly drives a Liquid Crystal Display (LCD), and includes a backplane driver.

A low-cost, high resolution indicating meter requires only a display, four resistors, and four capacitors. The TC7126A’s extremely low-power drain and 9V battery operation make it ideal for portable applications.
