3 Description

The LMH32401-Q1 automotive device is a

programmable-gain, single-ended-input to differentialoutput

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

rapidly recover 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, use this circuit

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 provides a low-power mode

using the EN pin. When the amplifier is in low-power

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.
