THREE CHANNEL LASER DRIVER
The ATR0807 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RW/DVD+RW (650 nm) and CD-RW (780 nm). It includes three channels for three different optical power levels which are controlled by a separate IC. The read channel generates a continuous output level, whereas the channels 2 and 3 are provided as write channels with very fast switching speeds. Write current pulses are enabled when a low signal is applied to the NE pins. All channels are summed together and switched to one of the two IOUTA or IOUTB outputs by the select input SELA. Each write channel (channel 2 and 3) can contribute up to 350 mA to the total output current, up to 500 mA. The rea...

FOUR CHANNEL LASER DRIVER
ATR0809 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm). It includes four channels for four different optical power levels. All channels (channel 1 = read channel, channel 2, 3, 4 = write channels) can be controlled by fast switches. The current pulses are enabled when a low signal is applied to the NE pins. All channels are summed together and switched to one of the two outputs IOUTA or IOUTB by the select input SELA. Each write channel (channel 2, 3 and 4) can contribute up to 350 mA to the total output current of up to 500 mA. The read channel can contribute up to 150 mA. Total gains of 100 (read channel), 250 (ch...

4-channel Laser Driver
The ATR0840 is a laser diode driver designed to operate two differently grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm). The device includes four channels for four different optical power levels. The write channels (channel 2 to 4) can be controlled either by fast LVDS (Low Voltage Differential Signaling) or by single-ended standard CMOS logic. In case of single-ended use, each of the ENABLE inputs (NEx or Ex) can be used, the complementary input may be left open. There is no need for blocking or connection to a reference voltage. The function of the read channel is to generate a continuous output current, channels 2 to 4 are designed as write channels with very fast switchi...

The ATR0841 is a laser diode driver designed to operate two differently grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm). The device includes four channels for four different optical power levels. The write channels (channel 2 to 4) can be controlled by fast LVDS (Low Voltage Differential Signaling). Due to the integrated termination external resistors are not needed. The function of the read channel is to generate a continuous output current, channels 2 to 4 are designed as write channels with very fast switching speed. All channels are summed together and routed to one of the two outputs, IOUTA or IOUTB, controlled by the select input SELA. Each write channel (channels 2 to...

4-channel LVDS Laser Diode Driver
The ATR0842 is a laser diode driver designed to operate two differently grounded laser diodes. The output, IOUTA, can be used for a blue laser diode (400 nm) with up to 6 V voltage drop by applying 8 V at pin VCCH. The other output, IOUTB, supports legacy laser diodes for DVD-RW/+RW/RAM (650 nm) and CD-RW (780 nm). The device includes four channels for four different optical power levels. The write channels (channel 2 to 4) can be controlled either by fast LVDS (Low Voltage Differential Signaling) or by single-ended standard CMOS logic. In case of single-ended use, each of the enable inputs (NEx or Ex) can be used, the complementary input may be left open. There is no need for blocking or co...
