5 / 43 page  OPT3001 www.ti.com SBOS681B – JULY 2014 – REVISED DECEMBER 2014 6.5 Electrical Characteristics At TA = 25°C, VDD = 3.3 V, 800-ms conversion time (CT = 1) (1), automatic full-scale range (RN[3:0] = 1100b(1)), white LED, and normal-angle incidence of light, unless otherwise specified. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT OPTICAL Peak irradiance spectral responsivity 550 nm Resolution (LSB) Lowest full-scale range, RN[3:0] = 0000b(1) 0.01 lux Full-scale illuminance 83865.6 lux 2812 3125 3437 ADC codes 0.64 lux per ADC code, 2620.80 lux full-scale Measurement output result (RN[3:0] = 0110)(1), 2000 lux input(2) 1800 2000 2200 lux Relative accuracy between gain 0.2% ranges(3) Infrared response (850 nm)(2) 0.2% Light source variation Bare device, no cover glass 4% (incandescent, halogen, fluorescent) Input illuminance > 40 lux 2% Linearity Input illuminance < 40 lux 5% Measurement drift across temperature Input illuminance = 2000 lux 0.01 %/°C 0 3 ADC codes Dark condition, ADC output 0.01 lux per ADC code 0 0.03 lux Half-power angle 50% of full-power reading 47 degrees PSRR Power-supply rejection ratio VDD at 3.6 V and 1.6 V 0.1 %/V(4) POWER SUPPLY VDD Operating range 1.6 3.6 V VI²C 1.6 5.5 V Operating range of I2C pull-up resistor I2C pull-up resistor, VDD ≤ VI²C Active, VDD = 3.6 V 1.8 2.5 µA Dark Shutdown (M[1:0] = 00)(1), 0.3 0.47 µA VDD = 3.6 V IQ Quiescent current Active, VDD = 3.6 V 3.7 µA Full-scale lux Shutdown, 0.4 µA (M[1:0] = 00)(1) POR Power-on-reset threshold TA = 25°C 0.8 V DIGITAL I/O pin capacitance 3 pF (CT = 1)(1), 800-ms mode, fixed lux range 720 800 880 ms Total integration time(5) (CT = 0)(1), 100-ms mode, fixed lux range 90 100 110 ms Low-level input voltage VIL 0 0.3 × VDD V (SDA, SCL, and ADDR) High-level input voltage VIH 0.7 × VDD 5.5 V (SDA, SCL, and ADDR) Low-level input current IIL 0.01 0.25(6) µA (SDA, SCL, and ADDR) Low-level output voltage VOL IOL= 3 mA 0.32 V (SDA and INT) Output logic high, high-Z leakage IZH Pin at VDD 0.01 0.25(6) µA current (SDA, INT) TEMPERATURE Specified temperature range –40 85 °C (1) Refers to a control field within the configuration register. (2) Tested with the white LED calibrated to 2k lux and an 850-nm LED. (3) Characterized by measuring fixed near-full-scale light levels on the higher adjacent full-scale range setting. (4) PSRR is the percent change of the measured lux output from its current value, divided by the change in power supply voltage, as characterized by results from 3.6-V and 1.6-V power supplies. (5) The conversion time, from start of conversion until the data are ready to be read, is the integration time plus 3 ms. (6) The specified leakage current is dominated by the production test equipment limitations. Typical values are much smaller.
