Full-scale frequency (See Note 3) S0=S1=H, S2=S3=L 1.1 MHz Temperature coefficient of output frequency λ ≤ 700 nm (See Note 4) ± 200 ppm/°C kSVS Supply voltage sensitivity VDD = 5 V ±10% ± 0.5 %/ V NOTES: 3. Full-scale frequency is the maximum operating frequency of the device without saturation. 4. The temperature coefficient of output frequency is measured with constant irradiance as the temperature is varied between −25°C and 70°C. The constant irradiance is sufficiently high that the output frequency is much greater than the dark frequency over the entire temperature range. Operating Characteristics at VDD = 5 V, TA = 25°C, Ee = 126 μW/cm2, λp = 640 nm (unless otherwise noted) PARAMETER TEST CONDITIONS TSL230RD TSL230ARD TSL230BRD UNIT PARAMETER TEST CONDITIONS MIN TYP MAX MIN TYP MAX MIN TYP MAX UNIT S0 = S1 = H, S2 = S3 = L 80 100 120 85 100 115 90 100 110 S1 = H, S0 = S2 = S3 = L 8 10 12 8.5 10 11.5 9 10 11 fO Output frequency S0 = H, S1 = S2 = S3 = L 0.8 1 1.2 0.85 1 1.15 0.9 1 1 kHz fO Output frequency S0 = S1 = S2 = H, S3 = L 40 50 60 42.5 50 57.5 45 50 55 kHz S0 = S1 = S3 = H, S2 = L 8 10 12 8.5 10 11.5 9 10 11 S0 = S1 = S2 = S3 = H 0.8 1 1.2 0.85 1 1.15 0.9 1 1.1 fD Dark frequency Ee = 0, S0 = S1 = H, S2 = S3 = L 0.4 10 0.4 10 0.4 10 Hz Re Responsivity S0 = S1 = H, S2 = S3 = L 0.79 0.79 0.79 kHz/ (μW/ cm2) t Output pulse S2 = S3 = L 125 600 125 600 125 600 ns tw Output pulse duration S2 or S3 = H 1/2fO 1/2fO 1/2fO s fO = 0 MHz to 10 kHz ± 0.1% ± 0.1% ± 0.1% Nonlinearity (See Notes 5 and 6) fO = 0 MHz to 100 kHz ± 0.2% ± 0.2% ± 0.2% %F.S.

Nonlinearity is defined as the deviation of fO from a straight line between zero and full scale, expressed as a percent of full scale. 6. Nonlinearity test condition: S0 = S1 = H, S2 = S3 = L. 7. Principal frequency is the internal oscillator frequency, equivalent to divide-by-1 output selection. |
