REF19xx Low-Drift Low-Power Voltage References

Texas Instruments REF19xx Low-Drift Low-Power Voltage References offers excellent temperature drift (25 ppm/°C, max) and initial accuracy (0.1%) on both the V_REF and V_BIAS outputs while operating at a quiescent current less than 430µA. The V_REF and V_BIAS outputs track each other with a precision of 6ppm/°C (max) across the temperature range of -40°C to 85°C. All these features increase the precision of the signal chain and decrease board space while reducing the cost of the system as compared to a discrete solution. The extremely low dropout voltage of only 10mV allows operation from very low input voltages, which can be very useful in battery-operated systems. Both the V_REF and V_BIAS voltages have the same excellent specifications and can sink and source current equally well. Texas Instruments REF19xx with very good long-term stability and low noise levels make these devices ideal for high-precision industrial applications.
