LTC6563 Four-Channel Transimpedance Amplifiers

Analog Devices LTC6563 Four-Channel Transimpedance Amplifiers (TIA) come with 600MHz bandwidth. The LTC6563 TIA’s low noise, wide linear range, and low power dissipation are ideal for LIDAR receivers using Avalanche photodiodes (APDs) and photodiodes (PDs). The amplifier features 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 current 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 the 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 a 100Ω external differential load.
