ISL21400 digitally programmable voltage reference allows users to set the temperature slope and DC voltage of its output to accurately compensate for temperature drifts elsewhere in the system. Engineers can generate a compensation voltage that will effectively cancel out the native drift of a system in the analogue domain, allowing the use of lower cost components. With the device one can address temperature drift cost-effectively without losing the simplicity of digital programming. It offers a 1.2V reference with an absolute accuracy of +2% and gives the user 8-bit control of slope and output-voltage level, plus three different gain settings. All settings are stored in on-chip EEPROM memory, which avoids the need for reprogramming each time the system is powered down. It is packaged in a cost-effective SO-8 form-factor and draws just 250μA.
