Low data processing overhead
4-wire SPI
The ADAL6110-16 is a light detection and ranging (LIDAR)
signal processor IC that supports simultaneous capture of up to
16 channels. Each channel is integrated with a 16-bit analog to
digital converter (ADC) to measure the optical return signal.
The ADAL6110-16 stores the captured waveforms to static
random access memory (SRAM) storage. The data output
readout and functional configuration of the LIDAR signal
processor occurs over a 4-wire serial port interface (SPI).
The LIDAR signal processor features a dc balance control to
reject signal offset and corruption due to modulated interference,
eliminating the need for external dc cancellation circuitry. In
addition, the LIDAR signal processor has a built-in automatic
gain control (AGC) that modifies the gain of the system to
ensure the signal of interest is automatically scaled to the
measurement range.

APPLICATIONS
Autonomous systems collision avoidance
Corridor mapping
Dynamic suspension and flight control
Drone altitude monitoring
Industrial distance measurement
Mounted safety curtain systems
Parking spot monitoring
The ADAL6110-16 simplifies the traditional multichannel
LIDAR system implementation by integrating the transimpedance
amplifier (TIA), gain and sampling stages, as well as providing
the transmitter fire signal, all of which are managed by on-chip
control logic. No external components are required between the
photodiodes and the TIA interface of each channel in the
LIDAR signal processor.
