LT6654 Precision Wide Supply High Output Drive Low Noise Reference
FeaTures DescripTion
n
Low Drift:
The LT®6654 is a family of small precision voltage ref- n
A-Grade: 10ppm/°C Max
erences that offers high accuracy, low noise, low drift, n
B-Grade: 20ppm/°C Max
low dropout and low power. The LT6654 operates from n
High Accuracy:
voltages up to 36V and is fully specified from –55°C to n
A-Grade: ±0.05% Max
125°C. A buffered output ensures ±10mA of output drive n
B-Grade: ±0.10% Max
with low output impedance and precise load regulation. n
Low Noise: 1.6ppmP-P (0.1Hz to 10Hz)
These features, in combination, make the LT6654 ideal n
Wide Supply Range to 36V
for portable equipment, industrial sensing and control, n
Low Thermal Hysteresis: LS8 15ppm (–40°C to 125°C)
and automotive applications. n
Long Term Drift: (LS8) 15ppm/√kHr
The LT6654 was designed with advanced manufactur- n
Line Regulation (Up to 36V): 5ppm/V Max
ing techniques and curvature compensation to provide n Low Dropout Voltage: 100mV Max 10ppm/°C temperature drift and 0.05% initial accuracy. n Sinks and Sources ±10mA Low thermal hysteresis ensures high accuracy and n Load Regulation at 10mA: 8ppm/mA Max 1.6ppm n P-P noise minimizes measurement uncertainty. Fully Specified from –55°C to 125°C Since the LT6654 can also sink current, it can operate n Available Output Voltage Options: 1.25V, 2.048V, as a low power negative voltage reference with the same 2.5V, 3V, 3.3V, 4.096V, 5V precision as a positive reference. n Low Profile (1mm) ThinSOT™ Package and 5mm × 5mm Surface Mount Hermetic Package The LT6654 references are offered in 6-lead SOT-23 package and an 8-lead LS8 package. The LS8 is a 5mm
