MAX1099数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

The MAX1098/MAX1099 implement both local andremote temperature sensing with 10-bit resolution, using+5V and +3V supply voltages, respectively. Accuracyis ±1°C from 0°C to +70°C, with no calibration needed.The devices feature an algorithmic switched-capacitoranalog-to-digital converter (ADC), on-chip clock, and3-wire serial interface compatible with SPI, QSPI™, andMICROWIRE®.
The MAX1098/MAX1099 also perform fully differentialvoltage measurements with 10-bit resolution and separatetrack-and-hold (T/N) for positive and negative inputs. Bothdevices accept versatile input modes consisting of two3-channel signal pairs, five 1-channel signals relative toAIN5, or VDD/4 relative to ground. An external referencemay be used for more accurate voltage measurements.
Typical power consumption is only 1.3mW (MAX1099). Ashutdown mode and two standby modes provide multiplestrategies for prolonging battery life in portable applicationsthat require limited sampling throughput.
The MAX1098/MAX1099 are available in 16-pin SSOPpackages.

简介

MAX1099属于集成电路（IC）的模数转换器（ADC）。由制造生产的MAX1099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。
