The MAX1098/MAX1099 implement both local and remote temperature sensing with 10-bit resolution, using +5V and +3V supply voltages, respectively. Accuracy is ±1°C from 0°C to +70°C, with no calibration needed. The devices feature an algorithmic switched-capacitor analog-to-digital converter (ADC), on-chip clock, and 3-wire serial interface compatible with SPI, QSPI™, and MICROWIRE®.
The MAX1098/MAX1099 also perform fully differential voltage measurements with 10-bit resolution and separate track-and-hold (T/N) for positive and negative inputs. Both devices accept versatile input modes consisting of two 3-channel signal pairs, five 1-channel signals relative to AIN5, or VDD/4 relative to ground. An external reference may be used for more accurate voltage measurements.
Typical power consumption is only 1.3mW (MAX1099). A shutdown mode and two standby modes provide multiple strategies for prolonging battery life in portable applications that require limited sampling throughput.
The MAX1098/MAX1099 are available in 16-pin SSOP packages.
