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.

簡介

MAX1099屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由制造生產(chǎn)的MAX1099模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。
