A compact guide covering the Analog Devices dc2900a evaluation board listing at Newark: a 16-channel APD receiver using ltc6561 TIAs, shipping waived for orders above $150, practical bundling tips, specification highlights, and procurement cautions. Includes a short Q&A and links to the Newark product and offer pages.

Deal snapshot

Engineers and lab buyers will note a current Newark listing for the Analog Devices dc2900a evaluation board, with shipping costs waived once an order exceeds $150. The offering is helpful when prototyping lidar receiver chains because it packages multiple detector channels and front-end amplification together.

Hardware overview

The dc2900a evaluation unit is a 16-channel optical receiver assembly built to feed a single output chain via multiplexing. It incorporates ltc6561 transimpedance amplifier ICs to convert detector current into a measurable voltage and pairs with a 16-element APD array sourced from firstsensor for broad sensitivity through the visible and near infrared bands.

Quick specification table

Attribute	Notes
Channels	16 (multiplexed to one output)
Amplifier	ltc6561, ~74 kohm TIA gain, ~30 µA linear input range
Detector	firstsensor APD array (~400nm–1100nm)
Output	AC-coupled for 50 Ω timing systems, ~2 Vpp swing on 100 Ω

Who benefits from this board

• Engineers needing a compact, bench-ready receiver chain instead of assembling discrete TIAs and wiring multiple channels.
• Students or researchers validating time-of-flight measurement setups who prefer a multiplexed single-channel capture on an oscilloscope.
• Teams evaluating ltc6561 performance within a real optical receiver configuration.

Savings playbook: practical ways to reduce total cost

1. Aggregate additional small items into the same order so the threshold for free shipping (orders over $150) is met and delivery is complimentary.
2. Combine the eval board with clearance or refurbished test gear available on Newark’s special pages; bundling reduces per-item freight impact.
3. Purchase frequently used passives and connectors in quantity—cables, adapters, and headers—to absorb handling across one shipment.

Common pitfalls and procurement notes

• Shipping savings disappear for single small-item purchases under the $150 threshold, so checkout totals should be planned when ordering accessories.
• Confirm compatibility of the APD array spectral sensitivity (~400nm–1100nm) with the intended illumination source before committing to the board for a given lidar wavelength.
• The ltc6561 output swing and AC coupling are optimized for timing capture into 50 Ω systems—measurement setups should account for the board’s expected impedance and coupling behavior.

Short Q&A

Q: Can the module drive a 50 Ω scope input directly?

A: Yes; the output is AC-coupled for time-domain work into 50 Ω test equipment, with approximately 2 Vpp available on a 100 Ω load.

Q: Is the amplifier suitable for heavy background light?

A: The ltc6561 supports about a 30 µA linear input current range and includes fast overload recovery, which helps with common lidar background light transients but should be validated for specific ambient conditions.
