Calculation
±0.25% = 2500 ppm
(25 ppm/°C)(60°C) = 1500 ppm
±0.003% = 30 ppm
±50 μV/20 mV = ±2500 ppm
(±0.5 μV/°C)(60°C) = 30 μV
30 μV/20 mV = 1500 ppm
±2.0 mV/20 mV = 1000 ppm
(±25 μV/°C)(60°C)= 1500 μV
1500 μV/20 mV = 750 ppm
(±15 nA)(100 Ω ) = 1.5 μV
1.5 μV/20 mV = 75 ppm
(±100 pA/°C)(100 Ω )(60°C) = 0.6 μV
0.6 μV/20 mV = 30 ppm
(±10 nA)(100 Ω ) = 1 μV
1 μV/20 mV = 50 ppm
(100 pA/°C)(100 Ω )(60°C) = 0.6 μV
0.6 μV/20 mV = 30 ppm
(10 nA)(175 Ω ) = 3.5 μV
3.5 μV/20 mV = 87.5 ppm
(100 pA/°C)(175 Ω )(60°C) = 1 μV
1 μV/20 mV = 50 ppm
115 dB = 1.8 ppm × 5 V = 8.8 μV
8.8 μV/20 mV = 444 ppm
0.3 μV p-p/20 mV = 15 ppm
