Price list for high-precision transimpedance amplifiers for data center interconnects

High-precision transimpedance amplifiers for data center interconnects are available from leading distributors like Mouser, Digi-Key, and GoPhotonics, with prices typically ranging from tens to hundreds of USD per unit depending on speed, gain, and features.

Overview of Available TIAs

Mouser Electronics offers a wide selection of TIAs from manufacturers such as Analog Devices, Texas Instruments, and others, with parametric filters to select devices by gain, bandwidth, and noise performance. Pricing is displayed per unit and varies with quantity, and tariffs may apply depending on shipping location . For example, the Analog Devices ADA4356 is a low-noise, wide dynamic-range TIA module suitable for high-speed optical measurements, supporting 20 ns pulse widths and programmable gain . Texas Instruments provides a dedicated TIA product line with datasheets and design resources, allowing selection based on bandwidth, input current range, and noise specifications . These devices are optimized for high-speed optical communication and data center interconnect applications. Digi-Key lists TIAs including instrumentation amplifiers, buffer amplifiers, and transconductance amplifiers, which are suitable for precision current-to-voltage conversion in photodiode-based systems. Prices vary depending on performance and packaging . GoPhotonics catalogs 69 TIAs from six manufacturers, including devices for 2.5 Gb/s to 43 Gb/s data rates, low-noise fiber channel applications, and automatic gain control (AGC) TIAs. Users can download datasheets and request quotes directly from manufacturers or distributors, which is essential for high-precision, high-speed applications .

Price Range

• Low-speed, general-purpose TIAs: approximately $20–$50 per unit
• High-speed, low-noise TIAs for optical interconnects (10–43 Gb/s): approximately $100–$500 per unit, depending on features like AGC, feedback resistor options, and integrated ADC modules
• Custom or µModule TIAs with integrated ADCs: pricing typically requires a quote from the distributor or manufacturer due to advanced specifications

Recommendations

1. Identify required bandwidth and gain for your data center interconnect application.
2. Check noise performance and linearity, especially for high-speed optical links.
3. Request quotes from distributors like Mouser, Digi-Key, or GoPhotonics for bulk pricing and lead times.
4. Review datasheets for thermal performance, input capacitance, and compatibility with photodiodes or APDs. By using these distributors' filtering tools, you can quickly narrow down TIAs that meet your precision, speed, and noise requirements while obtaining up-to-date pricing and availability.
