Analog Devices Inc. LT6654BX 2.5V Precision Voltage Reference
Analog Devices Inc. LT6654BX 2.5V Precision Voltage Reference operates from voltages up to 36V and is fully specified from -40°C to +175°C. A buffered output ensures both sourcing and sinking output current, with low output impedance and precise load regulation. These features make the LT6654BX an ideal choice for high-temperature applications.
Analog Devices LT6654BX features low thermal hysteresis to ensure high accuracy. The low 1.5ppmP-P output voltage noise rating minimizes measurement uncertainty. Because the LT6654BX can also sink current, it can operate as a low-power negative voltage reference with the same precision as a positive reference.
The LT6654BX Voltage Reference is offered in a 8-lead Micro Small Outline Package (MSOP).
