PRODUCTION DATA
请参考 PDF 数据表获取器件具体的封装图。
Select R1 and R2, as shown in Figure 8-9.
Use Equation 7 to select the appropriate resistor values.
R1 can be between 1k and 5k. (For best temperature coefficient and stability with time, use 1% metal film resistors)
R2 = 1 k (8.13 − 1) = 7.13 k, closest 1% value is 7.15 k
