LTC6258 Low Noise Reference Use LT6656 for a Low Current Starting Reference

Aug 30th 2017
The LT6656 is a 1µA precision series voltage reference. Yet with low power comes low drive current capability and higher noise. The LTC6259 can be used as a buffer that follows a filter to enhance the utilization of the LT6656 in low power applications. Figure 5a shows such a configuration. First a very low cutoff frequency ...

Wireless Current Sense Circuit Floats with Sense Resistor

Kris Lokere - Strategic Applications Manager Apr 25th 2017
Introduction Measuring the current that flows through a sense resistor seems easy. Amplify the voltage, read it with an ADC, and now you know what the current is. But it gets more difficult if the sense resistor itself sits at a voltage that is very different from system ground. Typical solutions bridge that voltage difference ...

Innovation Pushes State-of-the-Art in Voltage References

Brendan Whelan - Design Manager Nov 8th 2010
Most system designers use voltage references in their circuits. While many will agree that the performance may ultimately be limited by the reference, they are often unclear as to why. With so many reference products available, designers often choose based on a tradeoff between price and precision, using only initial accuracy ...

10ppm/ºC, 3mV Dropout Voltage Reference Operates with Less than 1μA

Apr 5th 2010
MILPITAS, CA — April 5, 2010 — Linear Technology announces the LT6656, a precision SOT23 voltage reference that operates on only 850nA of supply current. The LT6656 has an initial error of less than 0.05% and a guaranteed temperature drift of less than 10ppm/ºC. This combination of precision and ultralow power is ideal ...

Self Buffered Micropower Reference

Jan 1st 1987
The opamp provides controlled bias current to a shunt reference through its supply connection. Since the opamp can operate with both inputs and outputs at the low-side supply potential, the buffer action works properly for sourcing output current at the same voltage as the reference itself. ...

Dual Buffered ±0.617V Reference Powered by Two AA Batteries

Nov 1st 1983
Lower opamp is a precision inverter setting outputs to set the outputs at the same magnitude but opposite polarity. The upper opamp drives the positive output so that the difference of the two outputs is the reference voltage, so the result is that half the reference voltage is the magnitude of the outputs. ...
