Linear Technology LTC2995CUD#PBF
- Part Number:
- LTC2995CUD#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3283802-LTC2995CUD#PBF
- Description:
- IC TEMP SENSOR VOLT MNTR 20QFN
- Datasheet:
- LTC2995CUD#PBF
Description
The LTC2995 is a high-accuracy temperature sensor and dual supply monitor. It converts the temperature of an external diode sensor and/or its own die temperature to an analog output voltage while rejecting errors due to noise and series resistance. Two supply voltages and the measured temperature are compared against upper and lower limits set with resistive dividers. If a threshold is exceeded, the device communicates an alert by pulling low the correspondent open drain logic output.
The LTC2995 gives ±1°C accurate temperature results using commonly available NPN or PNP transistors or temperature diodes built into modern digital devices. Voltages are monitored with 1.5% accuracy. A 1.8V reference output simplifies threshold programming and can be used as an ADC reference input.
The LTC2995 provides an accurate, low-power solution for temperature and voltage monitoring in a compact 3mm x 3mm QFN package.
