TC7135CBU屬于集成電路（IC）的顯示驅(qū)動(dòng)器。由微芯科技股份有限公司制造生產(chǎn)的TC7135CBU顯示驅(qū)動(dòng)器顯示驅(qū)動(dòng)器是一種集成電路 (IC)，可在微處理器 (MPU)、微控制器 (MCU) 或其他電路系統(tǒng)之間提供轉(zhuǎn)換、接口和控制，用于 LCD、LED、OLED、DLP、真空熒光和 AMOLED 等顯示器。可能的通信接口和協(xié)議包括模擬、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.
