Product Details

The LTC6560 is a low-noise, transimpedance amplifier (TIA) with 220MHz bandwidth. The LTC6560’s low noise, high transimpedance and low power dissipation are ideal for LIDAR receivers using avalanche photodiodes (APDs). The LTC6560 features 74kΩ transimpedance gain and 30µA linear input current range. Using an input circuit with a total input capacitance of 2pF, the input current noise density is 4.8pA/√Hz at 200MHz. With lower capacitance, noise and bandwidth improve further. The LTC6560 operates from a single 5V supply and consumes only 90mW. Utilizing the LTC6560’s output MUX, multiple LTC6560 devices can be combined to a single output. The LTC6560’s fast overload recovery and fast output MUXing make it well suited for LIDAR receivers with multiple APDs. Its single-ended output can swing 2VP-P on a 100Ω load. Its low impedance op amp style output has been designed to drive back-terminated 50Ω cables.

The LTC6560 is packaged in a compact 3mm × 3mm 16-pin leadless QFN package with an exposed pad for thermal management and low inductance.
