MCP3465R中文资料16-Bit, 153.6kSPS, Single Channel ADC w/Vref数据手册Microchip规格书

描述 Description

The MCP3465R is a low-noise 16-bit Delta-Sigma Analog-to-Digital Converter (ADC), with two single-ended or one differential input channels and programmable data rate of up to 153.6 kSPS. It offers integrated features such as internal Vref, oscillator, temperature sensor and burnout sensor detection, in order to reduce system component count and total solution cost.

The MCP3465R ADC is fully configurable with Oversampling Ratio (OSR) from 32 to 98304 and gain from 0.33X to 64X. It includes an internal sequencer(SCAN mode) with multiple monitor channels and a 24-bit timer to be able to automatically create conversion loop sequences without needing MCU communications. Advanced security features such as CRC and register map lock, can guarantee configuration locking and integrity as well as communication data integrity for secure environments.

The device also features a 20 MHz SPI-compatible serial interface. Communication is largely simplified with 8-bit commands, including various continuous Read/Write modes and 24/32-bit multiple data formats that can be accessed by the Direct Memory Access (DMA) of an 8-bit, 16-bit or 32-bit MCU. The MCP3465R is available in an ultra-small, 2 mm x 2 mm UQFN-12 and is specified over an extended temperature range from -40°C to +125°C.

简介

MCP3465R属于集成电路（IC）的模数转换器（ADC）。由Microchip制造生产的MCP3465R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。
