Frequently Asked Questions
What output voltage accuracy and adjustment range does the LT1027ECS8-5#PBF provide?
The LT1027ECS8-5#PBF delivers a precision 5 V output with an adjustable range of ±0.05 V around the nominal value. This trim capability allows calibration to 4.95 V to 5.05 V, making it ideal for 12-bit to 16-bit ADC and DAC reference applications where initial offset correction is required.
How much output current can the LT1027ECS8-5#PBF supply, and what is its maximum input voltage?
The LT1027ECS8-5#PBF can source up to 15 mA of output current, sufficient to directly drive multiple ADC or DAC reference inputs simultaneously. Its maximum input voltage of 40 V supports compatibility with industrial 24 V and automotive 12 V power rails without requiring a pre-regulator stage.
Why is the LT1027ECS8-5#PBF preferred for 16-bit ADC reference designs over lower-precision alternatives?
The LT1027ECS8-5#PBF's ultra-low noise output and tight initial tolerance make it suitable for 16-bit ADC designs where a 1 LSB error corresponds to less than 80 µV on a 5 V range. Standard voltage references with higher noise or worse temperature coefficients would degrade ADC effective number of bits (ENOB) below 16 bits.
Can the LT1027ECS8-5#PBF be used in 4-20 mA industrial transmitter designs, and what supply voltage is needed?
Yes, the LT1027ECS8-5#PBF is well-suited for 4-20 mA industrial current loop transmitters, where a stable 5 V reference ensures accurate D/A conversion of measured variables. It requires a supply voltage at least 2 V above its 5 V output, so a 7.5 V to 40 V supply range covers virtually all industrial loop-powered transmitter topologies.
