The model number is a specific version of a generic that can be purchased or sampled. Status Status indicates the current lifecycle of the product. This can be one of 4 stages: Pre-Release: The model has not been released to general production, but samples may be available. Production: The model is currently being produced, and generally available for purchase and sampling.

These monolithic IC voltage references operate as a low-temperature-coefficient 2. A third terminal on the LM The LM The 2. Further, since the LM C while the LM C temperature range.

C, the LM C and the LM These limits are not used to calculate outgoing quality levels. Stability is defined as the maximum change in Vref from 25? C to TA min or TA max. Their low impedance and wide operating current range simplify biasing in almost any circuit.
Further, either the breakdown voltage or the temperature coefficient can be adjusted to optimize circuit performance. Figure 1 shows an LM with a 10k potentiometer for adjusting the reverse breakdown voltage. With the addition of R1 the breakdown voltage can be adjusted without affecting the temperature coefficient of the device. The adjustment range is usually sufficient to adjust for both the initial device tolerance and inaccuracies in buffer circuitry.
If minimum temperature coefficient is desired, two diodes can be added in series with the adjustment potentiometer as shown in Figure 2. When the device is adjusted to 2. Almost any silicon signal diode can be used for this purpose such as a 1N, 1N or a 1N For proper temperature compensation the diodes should be in the same thermal environment as the LM It is usually sufficient to mount the diodes near the LM on the printed circuit board.
The absolute resistance of R1 is not critical and any value from 2k to 20k will work. As used herein: 2. A critical component is any component of a life support 1. Life support devices or systems are devices or sysdevice or system whose failure to perform can be reatems which, a are intended for surgical implant into sonably expected to cause the failure of the life support the body, or b support or sustain life, and whose faildevice or system, or to affect its safety or effectiveness.
