SOT23 Voltage Reference Offers 10ppm/°C Drift While Limiting Noise to Only 1.6ppm
Linear Technology introduced the LT6654, a SOT23 series voltage reference designed specifically for precision operation from -40°C to 125°C. This voltage reference combines 0.05% initial accuracy, 10ppm temperature drift and low frequency noise of only 1.6ppm. The LT6654 can operate on a supply voltage as low as 100mV above the output, and it maintains a line regulation error of only 5ppm/V on a supply voltage up to 36V. The buffered output enables source or sink capability up to 10mA, and limits load regulation error to only 8ppm/mA.
In aThe LT6654 expands the precision and stability performance of SOT23 references, says Brendan Whelan, Design Manager for Linear Technology. This makes the LT6654 a strong candidate for automotive and industrial applications, as well as high resolution instrumentation and data acquisition.
The LT6654 is currently in production with a 2.5V output version. Additional voltage options will be available soon. Prices start at $1.55 each in 1,000-piece quantities. For more information, visit www.linear.com/6654.
