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.ApplicationsCommunication SystemsHandheld Instruments (PDAs, Palmtops)Industrial Process ControlsMedical Equipment
