HI7190IB规格书详情
The Intersil HI7190 is a monolithic instrumentation, sigma delta A/D converter which operates from ±5V supplies. Both the signal and reference inputs are fully differential for maximum flexibility and performance. An internal Programmable Gain Instrumentation Amplifier (PGIA) provides input gains from 1 to 128 eliminating the need for external pre-amplifiers. The on-demand converter autocalibrate function is capable of removing offset and gain errors existing in external and internal circuitry. The on-board user programmable digital filter provides over 120dB of 60/50Hz noise rejection and allows fine tuning of resolution and conversion speed over a wide dynamic range. The HI7190 and HI7191 are functionally the same device, but the HI7190 has tighter linearity specifications.

HI7190IB属于集成电路(IC) > 模数转换器(ADC)。瑞萨科技有限公司制造生产的HI7190IB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。
