LTR33xx Low-Drift, Low-Power, Small-Footprint Series Voltage Reference Data Sheet
●The LTR33 series devices are low temperature drift (20ppm/°C maximum), low-power, high-precision CMOS voltage reference, featuring ±0.1% initial accuracy, low operating current with power consumption less than 500μA. This device also offers very low output noise of 15 μVPP/V, which enables its ability to maintain high signal integrity with high-resolution data converters in noise critical systems.
●Packaged in the same SOT23-3 package, LTR33xx offers enhanced specifications and pin-to-pin replacement for REF33xx and LM4132. Stability and system reliability are further improved by the low output-voltage hysteresis of the device and low long-term output voltage drift. LTR33xx is specified for the wide temperature range of −40 to +125 °C.
■Features and Benefits:
●Voltage options: 1.25V, 1.5V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V
●Initial accuracy: ±0.1% (maximum)
●Low temperature coefficient: 20 ppm/°C (maximum)
●Output 1/f noise at 0.1 to 10 Hz: 15 μVPP/V
●Supply voltage: 2.7 to 5.5 V
●Power consumption: < 500 μA
●Startup time: <400us
●Operating temperature: −40 to 125 °C
●Output Current: ±5mA
