LT6656ACDC-2.5#TRPBF

Voltage Reference Overview

The LT6656ACDC-2.5#TRPBF is a precision series voltage reference with a fixed output of 2.5V, housed in a 6-lead (2mm × 2mm) plastic DFN package. It operates within an industrial temperature range of –40°C to 85°C and features an initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device draws a typical supply current of 1µA and supports a wide input voltage range up to 18V. It provides a minimum output drive current of 5mA with stable operation using capacitors of 1µF or larger.
