LTC6655/LTC6655LN
TYPICAL PERFORMANCE CHARACTERISTICS Characteristic curves are similar for most voltage options of the LTC6655. Curves from the LTC6655-1.25, LTC6655-2.5 and the LTC6655-5 represent the range of performance across the entire family of references. Characteristic curves for other output voltages fall between these curves and can be estimated based on their voltage output. 2.5V Low Frequency 2.5V Output Voltage 0.1Hz to 10Hz Noise Temperature Drift 2.5V Load Regulation (Sourcing)
