ADC1175中文资料8 位 20MSPS 模数转换器 (ADC)数据手册TI规格书

描述 Description

The ADC1175 is a low power, 20 Msps analog-to-digital converter that digitizes signals to 8 bits while consuming just 60 mW of power (typ). The ADC1175 uses a unique architecture that achieves 7.5 Effective Bits. Output formatting is straight binary coding.The excellent DC and AC characteristics of this device, together with its low power consumption and +5V single supply operation, make it ideally suited for many video, imaging and communications applications, including use in portable equipment. Furthermore, the ADC1175 is resistant to latch-up and the outputs are short-circuit proof. The top and bottom of the ADC1175's reference ladder is available for connections, enabling a wide range of input possibilities. The ADC1175 is offered in a TSSOP. It is designed to operate over the commercial temperature range of -20°C to +75°C.

简介

ADC1175属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADC1175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。
