Frequently Asked Questions
What is the output voltage accuracy and temperature coefficient of the LT6656AIS6-2.5#TRMPBF?
The LT6656AIS6-2.5#TRMPBF provides a 2.5 V output with ±0.05% initial accuracy, meaning the output stays between 2.49875 V and 2.50125 V at room temperature. The temperature coefficient is 10 ppm/°C maximum, so across the full -40°C to +125°C range the output shifts by less than 1.65 mV, making it suitable for precision 12-bit and 16-bit ADC reference applications.
Is the LT6656AIS6-2.5#TRMPBF qualified for automotive applications?
Yes, the LT6656AIS6-2.5#TRMPBF carries AEC-Q100 automotive qualification with an operating temperature range of -40°C to +125°C. It is designed for use in automotive electronic control units, ADAS sensor interfaces, battery management systems, and powertrain controllers where stable 2.5 V reference voltages are required under extreme thermal and vibration conditions.
What is the minimum input voltage required to maintain the 2.5 V output of the LT6656AIS6-2.5?
The LT6656AIS6-2.5 operates with an input voltage as low as 2.7 V to maintain regulated 2.5 V output, providing only 200 mV of required headroom. This low dropout characteristic allows direct use on 3.3 V rails common in microcontroller and FPGA systems, and the 5 mA output current is sufficient to drive most ADC reference inputs without an additional buffer stage.
What package does the LT6656AIS6-2.5#TRMPBF use and how does it simplify PCB layout?
The device comes in a 6-pin TSOT-23 package measuring approximately 2.9 mm x 1.6 mm, one of the smallest voltage reference footprints available. This compact size allows placement within 5 mm of ADC reference pins to minimize trace inductance and noise pickup. The Pb-free tape-and-reel (TRMPBF) format supports automated SMT assembly compatible with RoHS-compliant reflow processes at 260°C peak.
