3 Description
The LMH32401 device is a programmablegain,
single-ended, input-to-differential output
transimpedance amplifier for light detection and
ranging (LIDAR) applications and laser distance
measurement systems. The LMH32401 device can be
configured in a gain of 2 kΩ or 20 kΩ. The LMH32401
device has 1.5 VPP of output swing and is designed to
drive a 100-Ω load.
The LMH32401 device has an integrated 100-mA
clamp that protects the amplifier and allows the device
to recover rapidly from an overloaded input condition.
The LMH32401 device also features an integrated
ambient light cancellation circuit that can be used
instead of AC coupling between the photodiode and
the amplifier to save board space in addition to
reducing system cost. The ambient light cancellation
circuit can be disabled in cases where DC coupling is
required.
The LMH32401 device can be placed in low-power
mode using the EN pin to conserve power when
the amplifier is not being used. Putting the amplifier
in low-power mode places its output pins in a
high-impedance state. This feature allows several
LMH32401 amplifiers to be multiplexed to a single
ADC with the EN control pin serving as the multiplexer
select function.
