LMH34400IDRLR Description

Short technical summary and product information.

The LMH34400IDRLR from Texas Instruments is a compact, fixed-gain, single-ended transimpedance amplifier. It is specifically designed for applications such as light detection and ranging (LIDAR) and laser distance measurement systems.

 

This amplifier boasts a gain bandwidth product of 240 MHz and an integrated gain of 40 kΩ. It features a low input-referred noise of 50 nA RMS and a fast rise/fall time of 1.5 ns. The device operates within a supply voltage range of 3 V to 3.45 V and an extended temperature range of -40°C to 125°C.

 

Key features include an integrated 100-mA protection clamp, which safeguards the amplifier and allows for rapid recovery from overloaded input conditions. Additionally, an integrated ambient light cancellation (ALC) circuit is provided, which can eliminate the need for AC coupling between the photodiode and amplifier, saving board space and system cost. The ALC loop can be disabled for signals below 400 kHz.

 

The LMH34400IDRLR is housed in a small SOT-5X3 surface-mount package, measuring 2.56 mm². Its quiescent current is 20 mA, with a low-power mode current of 1.5 mA.
