Transimpedance Amplifier with Selectable Gain

and Input Current Clamp

MAX40213

General Description

Benefits and Features

The MAX40213 is a transimpedance amplifier for optical

distance measurement receivers in LiDAR applications.

Low noise, high gain, low group delay, and fast recovery

from overload make this TIA ideal for distance-measure-

ment applications. Important features include 1.1pA/√Hz

input-referred noise density, an internal 2A input clamp,

pin-selectable 150kΩ and 750kΩ transimpedance (into a

1kΩ load), and wide bandwidth (300MHz, typ). An offset

current input allows optional adjustment of input offset cur-

rent. The MAX40213 has a shutdown (SD) control input

that reduces the supply current to 0.01μA. This transim-

pedance amplifier is available in a 8-bump WLP, and is

specified over the -40°C to +85°C operating temperature

range.

● Optimized for C = 0.25pF to 5pF

● Bandwidth = 300MHz (typ)

● 1.1pA/√Hz Input-Referred Noise

● Two Pin-Selectable Transimpedance Values

(R = 1kΩ)

• 150kΩ

• 750kΩ

● Internal Clamp for Input Current up to 2A (Transient)

● Fast Overload Recovery: 25ns at 100mA

● Offset Input Provides Offset Adjust Feature

● SD Input Shuts Down Internal Circuitry

● 3.3V Operation

● 1.75mm x 1.24mm, 8-Bump WLP

Applications

● Optical Distance Measurement

● LIDAR Receivers

● Industrial Safety Systems
