Maxim Integrated MAX1299
The MAX1298/MAX1299 implement local and remote temperature sensing with 12-bit resolution, using +5V and +3V supply voltages, respectively. The devices feature an algorithmic switched-capacitor analog-to-digital converter (ADC), an on-chip clock, and a 3-wire serial interface compatible with SPI, QSPI™, and MICROWIRE®. The MAX1298/MAX1299 also perform fully differential voltage measurements with 12-bit resolution and separate track-and-hold (T/H) for positive and negative inputs.

GENERAL DESCRIPTION
Accuracy is ±1°C from 0 to +70°C, with no calibration needed. Both devices accept versatile input modes consisting of two 3-channel signal pairs, five 1-channel signals relative to an 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 (MAX1299). A shutdown mode and two standby modes provide multiple strategies for prolonging battery life in portable applications that require limited sampling throughput. The MAX1298/MAX1299 are available in 16-pin SSOP packages. ________________________Applications Temperature/Voltage Supervision of Workstations and Communications Equipment Hand-Held Instruments Medical Equipment Industrial Process Control FEATURES
