IR TRANSMITTER
Note 1: All supply current measurements are made under the following conditions: no load at all outputs, input voltages at GND or
VCC, no PIN diode input current.
Note 2: Equivalent input current noise is calculated by dividing the output noise of the transimpedance amplifier by the midband
transimpedance gain.
Note 3: Sensitivity is measured with an IrDA-compliant input signal, where the data rate is within the Supported Data Rate, rise/fall
times are less than 600ns, and pulse widths are between 1.41s and 3/16 of the baud rate.
ELECTRICAL CHARACTERISTICS (continued)
(VCC = +3.0V to +5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C and VCC = +3.3V.)
