Product Description

The LM87CIMT is a highly integrated Data Acquisition System for hardware monitoring of servers, personal computers or virtually any microprocessor-based system. The LM87 has an on-chip digital output temperature sensor with 8-bit resolution as well as the capability of monitoring 2 external diode temperatures to 8-bit resolution, an 8 channel analogue input ADC with 8-bit resolution and an 8-bit DAC. A channel on the ADC measures the supply voltage applied to the LM87, nominally 3.3 V. Two of the ADC inputs can be redirected to a counter that can measure the speed of up to 2 fans. A slow speed ΣΔ ADC architecture allows stable measurement of signals in an extremely noisy environment. The DAC, with a 0 to 2.5 V output voltage range, can be used for fan speed control. Additional inputs are provided for Chassis Intrusion detection circuits and VID monitor inputs. The VID monitor inputs can also be used as IRQ inputs if VID monitoring is not required.
Remote diode temperature sensing (2 channels)
8 Positive voltage inputs with scaling resistors for monitoring +5 V, +12 V, +3.3 V, +2.5 V, Vccp
Chassis intrusion detector input
VID0-VID4 or IRQ0-IRQ4 monitoring inputs
