3 Description
The LMH32401-Q1 automotive device is a
programmable-gain, single-ended, input-to-differential
output transimpedance amplifier for light detection
and ranging (LIDAR) applications. The LMH32401-Q1
can be configured in a gain of 2 kΩ or 20 kΩ. The
LMH32401-Q1 has 1.5 VPP of output swing and is
designed to drive a 100-Ω load.
The LMH32401-Q1 has an integrated 100-mA clamp
that protects the amplifier and allows the device to
recover rapidly from an overloaded input condition.
The LMH32401-Q1 also features an integrated
ambient-light cancellation circuit. To save board
space, as well as reduce system cost, this circuit
can be used instead of ac coupling between the
photodiode (PD) or avalanche photodiode (APD) and
the amplifier. The ambient-light cancellation circuit can
be disabled in cases where dc coupling is required.
To conserve power when the amplifier is not being
used, the LMH32401-Q1 can be placed in low-power
mode using the EN pin. When the amplifier is in lowpower
mode, the output pins are in a high-impedance
state. This feature allows several LMH32401-Q1
amplifiers to be multiplexed to a single ADC with
the EN control pin serving as the multiplexer select
function.
