Overview
The HMC6590 is a high-speed, high-gain, low-power limiting transimpedance amplifier (TIA) designed by Analog Devices Inc. This component is specifically tailored for use in optical receivers, supporting data rates up to 43 Gbps. It features low input-referred noise, a 36 GHz bandwidth, and a differential small signal transimpedance of 4 kOhm. The HMC6590 is available in die form and includes an on-chip VCC bypass capacitor, requiring only a single external supply decoupling capacitor for operation. It operates on a single 3.3V ±5% supply and typically dissipates less than 300 mW of power.
