TC7135CLI集成电路（IC）的显示驱动器规格书PDF中文资料

TC7135CLI属于集成电路（IC）的显示驱动器。由美国微芯科技公司制造生产的TC7135CLI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 TC7135 4-1/2 digit analog-to-digital converter (ADC) offers 50 ppm (1 part in 20,000) resolution with a maximum nonlinearity error of 1 count. An auto-zero cycle reduces zero error to below 10 µV and zero drift to 0.5 µV/°C. Source impedance errors are minimized by a 10 pA maximum input current. Roll-over error is limited to ±1 count.
