3 Description
The LMH34400 is the industries' smallest, fixedgain,
single-ended transimpedance amplifier for light
detection and ranging (LIDAR) applications and laser
distance measurement systems. The LMH34400 can
produce 1.0 VPP of output swing and has an input
referred noise of 50 nARMS.
The LMH34400 has an integrated 100-mA clamp
that protects the amplifier and allows the device to
recover rapidly from an overloaded input condition.
The LMH34400 also features an integrated ambient
light cancellation (ALC) circuit that can be used
instead of AC coupling between the photodiode and
the amplifier to save board space and system cost.
The ALC loop should be disabled in cases where
frequency signal content less than 400 kHz needs to
be measured.
The LMH34400 can be placed in low-power mode
using the EN pin to conserve power when the
amplifier is not being used. This feature allows several
LMH34400 amplifiers to be multiplexed to the input of
the next stage of the receive signal chain with the EN
control pin serving as the multiplexer select function.
The LMH34400 offers single-ended output and is
optimized to be used with time-to-digital converter
(TDC) based LIDAR systems.
