OUTPUT VOLTAGE OUTHIGH 2.0 V OUTLOW 2.0 V INPUT REFERRED NOISE4 CF1 = 0.9 pF, G = 10 Normal CPANEL = 38 pF 993 e−rms Low Power CPANEL = 61 pF 2000 e−rms PANEL CAPACITANCE 0 80 pF LINEARITY ERROR5 CF1 = 0.9 pF, G = 5 Normal 0.03 + 1 % + LSB Low Power 0.2 + 8.2 % + LSB OPERATING TEMPERATURE Ambient, normal and low power 0 85 °C 1 Defined as the output voltage divided by the input charge (number of electrons in this case) with the gain amp setting (G = 1). This includes the gain error of the gain amp. 2 Each gain at G = 2, G = 4, G = 8, and G = 10 is calculated as the ratio of each output voltage to that at G = 1. Each measurement corresponds to the selection of each gain setting capacitor. 3 Gain deviation over temperature. 4 The output noise voltage is measured and converted into the input referred noise electrons. 5 It is defined as the deviation from a best fit line, including the origin. The output voltage is measured with five different input conditions. Rev.
