Key specifications at a glance

Item	Specification
Board	DC827A-B demonstration board for the LTC2804
Input supply	1.8V to 5.5V
Logic supply	1.8V to 5.5V
Driver slew rate	up to 150 V/µs at RL = 3 kohm, with CL between 50 pF and 2.5 nF
Maximum data rate	1000 kbps at RL = 3 kohm and CL = 250 pF

Purchase playbook

• Meet the free-shipping threshold: combine the DC827A-B with other parts so the subtotal reaches $150 to trigger free shipping on orders over $150.
• Check clearance and specials: pair the board with serial cables, connectors, or related accessories listed on the same site to consolidate an order.
• Group multiple evaluation boards or components into a single cart so per-item freight impact is reduced.

Technical notes and use cases

The DC827A-B is provided for testing the LTC2804’s behavior when translating between low-voltage logic rails and RS-232 levels. Because both input and logic supplies accept 1.8V to 5.5V, the board supports interfacing modern microcontrollers to classic serial equipment without fabricating a custom PCB first.

Q&A

Q: What is the primary purpose of this board?

A: Evaluation and bench testing of the LTC2804 single and dual RS-232 transceivers.

Q: Will the board run with 3.3V logic?

A: Yes — logic supply range includes 1.8V to 5.5V, so 3.3V operation is supported.

Q: Where to view or order it?

A: The Newark listing carries the item under Analog Devices; the DC827A-B appears on DailyBargains’ Newark page: Newark demo boards and transceivers.

Practical pitfalls to consider

• Evaluation boards are meant for testing — the component placement and connectors may not match a production design, so treat the DC827A-B as a reference rather than a final module.
• Observe the load conditions quoted for slew rate and data rate (RL and CL values) when comparing lab results to datasheet numbers.
• Confirm that any bundled items used to hit the free shipping mark are compatible and genuinely needed to avoid unnecessary purchases.
