Product Overview

LTC6561IUF#PBF is a low-noise four-channel, transimpedance amplifier. The LTC6561 multi-channel transimpedance amplifier’s low noise, high transimpedance, and low power dissipation are ideal for LIDAR receivers using APDs. The amplifier features 74Kohm transimpedance gain and 30µA linear input current range. Using an APD input circuit with a total capacitance of 2pF, the input current noise density is 4.5pA/√Hz at 200MHz. With lower capacitance, noise and bandwidth improve further. Only a 5V single supply is needed and the device consumes only 200mW. Utilizing internal 4-to-1 MUX along with the LTC6561’s output MUX; multiple 4-channel LTC6561 devices can be combined to directly interface with 8, 12, 16 and 32-channel APD arrays. LTC6561’s fast overload recovery and fast channel switchover make it well suited for LIDAR receivers with multiple APDs. Its single-ended output can swing 2VP-P on a 100Ω load. While its low impedance op-amp-style output can drive back-terminated 50Ω cables.
