Analog Devices Inc. DC1501A-C

Overview

DC1501A-C from Analog Devices (formerly Linear Technology) is a demonstration board for the LT1806 single rail-to-rail input/output precision op amp, featuring 325MHz gain-bandwidth, 140V/μs slew rate, and 85mA output current. It enables high-fidelity signal conditioning in low-voltage, high-frequency applications such as A/D driver circuits and active filters.

For engineers reviewing the DC1501A-C datasheet, DC1501A-C pinout, DC1501A-C application, or DC1501A-C equivalent, this board supports rapid evaluation of LT1806 performance under real-world conditions-including rail-to-rail swing, low distortion (–80dBc at 5MHz), and wide supply range (2.5V to 12.6V)-with configurable gain, termination, and layout-optimized signal paths.

Technical Context

The DC1501A-C implements the LT1806 in an 8-pin SO package with standard op amp pinout and includes on-board gain-setting resistors, bypass capacitors, and test points for differential and single-ended configurations. It supports ±5V, +5V/0V, and +3V/0V supplies and features a dedicated shutdown control interface for power management validation.

Designed for high-speed, low-noise applications, the board incorporates optimized PCB layout practices-ground plane separation, short trace routing, and controlled-impedance paths-to preserve the LT1806's 3.5nV/√Hz input voltage noise and maintain full-power bandwidth up to 10MHz at 4V_P-P output.

FAQ

What is the primary function of the DC1501A-C evaluation board?

The DC1501A-C evaluation board is designed to demonstrate and validate the performance of the LT1806 single rail-to-rail input/output op amp. It provides a fully assembled, tested platform with configurable gain, termination, and supply options-enabling engineers to verify key parameters including 325MHz gain-bandwidth, –80dBc distortion at 5MHz, and rail-to-rail output swing before integrating the LT1806 into final designs.

Does the DC1501A-C support both single-supply and split-supply operation?

Yes, the DC1501A-C supports both configurations: single-supply (e.g., +5V/0V or +3V/0V) and split-supply (e.g., ±5V). The board includes jumper-selectable power entry points and decoupling networks optimized for each mode, ensuring stable LT1806 operation across its full 2.5V to 12.6V total supply range without performance degradation.

Can the DC1501A-C be used to evaluate the LT1806's power-down functionality?

Yes, the DC1501A-C includes direct access to the LT1806's SHDN pin via a test point and series resistor, enabling precise validation of shutdown behavior. Measured turn-on time is 80ns and turn-off time is 50ns into a 100Ω load-critical for power-gated signal chains-and disable supply current drops to 0.4mA at 5V, confirming low-quiescent operation during sleep states.

What layout features of the DC1501A-C help preserve the LT1806's high-frequency performance?

The DC1501A-C uses a 4-layer PCB with dedicated ground and power planes, minimized trace lengths for feedback and input paths, 50Ω controlled-impedance routing where applicable, and strategically placed 0.1μF ceramic bypass capacitors near the LT1806 V+ and V– pins. These features suppress parasitic inductance and maintain signal fidelity up to 10MHz full-power bandwidth and 325MHz small-signal gain-bandwidth.

Is the DC1501A-C compatible with the LT1806 in TSOT-23 packaging?

No-the DC1501A-C is configured for the LT1806 in 8-pin SO package only, matching the standard op amp pinout shown in the SO-8 schematic diagram. While the LT1806 is also offered in 6-pin TSOT-23, that variant requires a different footprint and lacks the SHDN pin in the same location; therefore, the DC1501A-C does not support mechanical or electrical substitution of the TSOT-23 version without hardware modification.
