ISL21400 - Programmable Temperature Slope Voltage Reference

Key Features

  • a precision voltage reference combined with a temperature sensor whose output voltage varies linearly with temperature. The precision 1.20V reference has a very low temperature coefficient (tempco), and its output voltage is scaled by an internal DAC (VREF) to produce a temperature stable output voltage that is programmable from 0V to 1.20V. The output voltage from the temperature sensor (VTS) is summed with VREF to produce a temperature dependent output voltage. The slope of the VTS portion of.

DATASHEET ISL21400 Programmable Temperature Slope Voltage Reference FN8091 Rev 3.00 March 31, 2011 The ISL21400 features a precision voltage reference combined with a temperature sensor whose output voltage varies linearly with temperature. The precision 1.20V reference has a very low temperature coefficient (tempco), and its output voltage is scaled by an internal DAC (VREF) to produce a temperature stable output voltage that is programmable from 0V to 1.20V. The output voltage from the temperature sensor (VTS) is summed with VREF to produce a temperature dependent output voltage. The slope of the VTS portion of the output voltage can be programmed to be positive or negative in the range -2.1mV/°C to +2.1mV/°C.
