LTC6655CHMS8-2.5#PBF

Overview

The LTC6655CHMS8-2.5#PBF is a precision bandgap voltage reference from Analog Devices, offering an output of 2.5V with ±0.025% initial accuracy and a maximum temperature coefficient of 2ppm/°C. It operates within a supply range of VOUT + 0.5V to 13.2V, drawing 7mA typical supply current. The device features low noise (0.25ppm P-P at 0.1Hz–10Hz) and supports ±5mA source/sink currents. Housed in an 8-lead MSOP package, it functions across –40°C to 125°C.

Feature Summary

• Advanced curvature compensation ensures high accuracy and predictable drift characteristics.
• Capable of sourcing and sinking up to 5mA for flexible load regulation.
• Includes a shutdown mode to minimize power consumption when inactive.

Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• Precision battery monitors
