MCP37D11-80中文资料12-Bit, 80MSPS, 8-Ch ADC数据手册Microchip规格书

描述 Description

The MCP37D11-80 is a 12-bit pipelined A/D converter with a maximum sampling rate of 80 Msps. The high accuracy of 70.9 dB Signal-to-Noise Ratio (SNR) and over 92.2 dB Spurious Free Dynamic Range (SFDR) enable high precision measurements of fast input signals. The device operates at very low power consumption of 311 mW at 80 Msps including LVDS digital I/O. Lower power saving modes are available at 79 mW for Standby and 22 mW for Shutdown. The MCP37D11-80 includes many digital processing features that simplify system design, cost and power usage. These include an integrated digital down-converter with onboard NCO, decimation filters for improved SNR, a noise-shaping requantizer for SNR improvement around a bandwidth of interest, individual phase, offset and gain adjustment and a fractional delay recovery for time-delay corrections in multi-channel modes. Data is available through the serial DDR LVDS or parallel CMOS interface and configured via SPI. The device is available in the TFBGA-121 is qualified for automotive applications (AEC-Q100).

简介

MCP37D11-80属于集成电路（IC）的模数转换器（ADC）。由制造生产的MCP37D11-80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。
