DESCRIPTION

Four-Channel

Transimpedance Amplifier

with Output Multiplexing

The LTC®6563 is a low-noise four-channel transimpedance

amplifier (TIA) with 600MHz bandwidth. The LTC6563

TIA’s low noise, wide linear range, and low power dissipa-

tion are ideal for LIDAR receivers using Avalanche photo-

diodes (APDs) and photodiodes (PDs). The amplifier fea-

tures selectable 22.2/16.7/11.1/5.55kΩ Transimpedance

gain (RT) and 90µA linear input current range. Using an

APD with a total input capacitance of 0.5pF, the input cur-

rent noise density is 1.8pA/√Hz at 100MHz and 3.7pA/√Hz

at 600MHz. The LTC6563 consumes between 194mW and

325mW on a 3.3V supply depending on output mode.

An internal 4-to-1 MUX simplifies the system design. In

addition, external multiplexing capability allows channel

expansion up to 64 channels, saving space and power.

Fast overload recovery and fast channel switchover make

the LTC6563 well suited for LIDAR receivers with multiple

APDs. The built-in high-speed differential ADC driver can

swing as much as 2VP-P while driving into 100Ω external

differential load.

The LTC6563 is packaged in a 3mm × 5mm 24-pin

exposed pad QFN package with wettable flanks.
