STMicroelectronics STEVAL-CCA036V1

Overview

STEVAL-CCA036V1 from STMicroelectronics is a demonstration board for evaluating single-channel operational amplifiers in SO8 packages, supporting configurable Sallen-Key low-pass/high-pass filters, differential amplifiers, AC-coupled circuits, and in-loop/out-of-loop compensation topologies. It features 0805 footprints, dual decoupling (10 nF + 4.7 µF per supply rail), BNC input/output connectors, and surface-mount layout optimized for op-amp characterization prior to system integration.

For engineers reviewing the STEVAL-CCA036V1 datasheet, STEVAL-CCA036V1 schematic, STEVAL-CCA036V1 application configurations, or STEVAL-CCA036V1 compatibility with SO8 op-amps, this board enables rapid validation of gain, bandwidth, phase margin, noise, and stability behavior across multiple analog signal conditioning topologies without custom PCB design.

Technical Context

The board implements a universal SO8 op-amp socket with fully accessible inverting/non-inverting inputs, output, and dual supply pins (Vcc+, Vcc−), plus ground-referenced guard traces (GVIn−, GVIn+, GOut) to minimize leakage and parasitic coupling. All critical signal paths are routed with controlled impedance and short trace lengths to preserve high-frequency fidelity up to tens of MHz.

Resistor and capacitor footprints support flexible configuration: Z1–Z14 are unpopulated pads for external feedback and compensation networks; C1/C3 (10 nF) and C2/C4 (4.7 µF) provide broadband power supply decoupling; BNC connectors enable direct oscilloscope or function generator interfacing with minimal adapter loss.

FAQ

What op-amp packages does STEVAL-CCA036V1 support?

STEVAL-CCA036V1 supports only SO8-packaged single-channel operational amplifiers with standard JEDEC MS-012AC pinout (e.g., pins 1–8 mapping to NC, OUT, IN−, IN+, V−, V+, NC, NC). It does not accommodate TSSOP, MSOP, or DFN variants due to mechanical and pad layout constraints.

Can STEVAL-CCA036V1 be used for unity-gain stable op-amps?

Yes - the board's unpopulated feedback network pads (Z1–Z14) and guard-trace layout allow stable unity-gain configurations. Users must populate appropriate resistors/capacitors per the op-amp's datasheet stability requirements; no onboard components force a minimum gain.

Does the board include power supply regulation?

No - STEVAL-CCA036V1 has no onboard voltage regulators or LDOs. It requires external ±5 V, ±12 V, or ±15 V dual supplies connected via screw terminals or header pins. Power rails are brought directly to the op-amp's Vcc+ and Vcc− pins with dedicated decoupling.

Is there a bill of materials (BOM) for populated components?

The board ships unpopulated except for C1, C2, C3, C4, and the SO8 socket. The official data brief (DocID024760) lists all footprints and recommended values but does not specify a default populated BOM - users select components based on target op-amp and desired circuit topology.
