TC7109A规格书详情
描述 Description
The TC7109A is a 12-bit plus sign, CMOS low-power analog-to-digital converter (ADC). Only eight passive components and a crystal are required to form a complete dual-slope integrating ADC. The improved Voh source current TC7109A has features that make it an attractive per-channel alternative to analog multiplexing for many data acquisition applications. These features include typical input bias current of 1pA, drift of less than 1 µV/°C, input noise typically 15 µVp-p, and auto-zero. True differential input and reference allow measurement of bridge-type transducers such as load cells, strain gauges, and temperature transducers. In the handshake mode, the TC7109A will operate with industry-standard UARTs in controlling serial data transmission - ideal for remote data logging. The TC7109A has improved overrange recovery performance and higher output drive capability than the TC7109.

简介
TC7109A属于集成电路(IC)的模数转换器(ADC)。由Microchip制造生产的TC7109A模数转换器(ADC)模数转换器(ADC、A/D 或 A 转 D)对模拟信号进行采样,例如由麦克风采集的声音或传感器的输出,然后将其转换为数字信号。一般来说,数字输出是二进制补码二进制数,与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构(例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式)进行选择。
