MAX1299CEAE+

The MAX1299CEAE+ is a 12bit serial output temperature sensor with 5-channel ADC in 16 pin SSOP package. The implement local and remote temperature sensing with 12bit resolution. Accuracy is ±1°C from 0 to +70°C with no calibration needed. The device features an algorithmic switched-capacitor ADC, an on-chip clock and a 3-wire serial interface compatible with SPI, QSPI™ and MICROWIRE®. It also performs fully differential voltage measurements with 12bit resolution and separate track and hold for positive and negative inputs. 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. A shutdown mode and two standby modes provide multiple strategies for prolonging battery life in portable applications that require limited sampling throughput.
