LT6654BX 175°C, Wide Supply 2.5V Precision Voltage Reference
FEATURES DESCRIPTION
n
2.5V Output Voltage
The LT®6654BX is a 2.5V precision voltage reference that n
100% Tested at 175°C
is rated for operation up to 175°C junction temperature. n
Total Error < 1% Over –40°C to 175°C
The LT6654BX operates from voltages up to 36V and is n
Low Thermal Hysteresis: 30ppm Over –40°C to 175°C
fully specified from –40°C to 175°C. A buffered output n
Wide Supply Range to 36V
ensures both sourcing and sinking output current, with n Long Term Drift: 50ppm/√kHr low output impedance and precise load regulation. These n Line Regulation(Up to 36V): 30ppm/V Max at 175°C features, in combination, make the LT6654BX well posi- n Low Dropout Voltage: 120mV Max at 175°C tioned for high temperature environment applications. n Sources 3mA and Sinks 10mA at 175°C Low thermal hysteresis ensures high accuracy and n Load Regulation 50ppm/mA Max at 175°C 1.5ppmP-P noise minimizes measurement uncertainty. n Low Noise 1.5ppmP-P (0.1Hz to 10Hz) Since the LT6654BX can also sink current, it can oper- n No Thermal Shutdown ate as a low power negative voltage reference with the n Fully Specified from –40°C to 175°C same precision as a positive reference.
