STMicroelectronics STEVAL-CCA022V1

Overview

STEVAL-CCA022V1 from STMicroelectronics is a demonstration board designed to characterize single operational amplifiers in SC70-5, SOT-23-5 (two pinout variants), SOT-23-6, and SC70-6 packages. It supports configurable topologies including low-pass/high-pass Sallen-Key filters, differential amplifiers, AC-coupled circuits, and in-loop/out-of-loop compensation networks. The board accommodates op-amps such as TS507, TSV621, TSV911, and TS971 for lab evaluation.

For engineers reviewing the STEVAL-CCA022V1 datasheet, STEVAL-CCA022V1 pinout configuration options, STEVAL-CCA022V1 application schematics, or STEVAL-CCA022V1 equivalent evaluation platforms, this board provides flexible, solderless reconfiguration of gain, feedback, and compensation paths-enabling rapid op-amp AC/DC performance validation without custom PCB design.

Technical Context

The board implements dual supply rail connections (VCCP/VCCN) and features 14 unpopulated impedance locations (Z1–Z14) for user-defined resistors and capacitors, enabling precise control over pole/zero placement in filter and compensation circuits. Input/output SMB connectors (Vin+_SMB, Vin-_SMB, Vout_SMB) support direct signal injection and measurement with minimal parasitic loading.

It supports both inverting and non-inverting configurations via jumper-selectable ground reference points (GIn+, GIn-, GOut) and dedicated bias networks. The VCC+ connection for standby pins on SOT-23-6/SC70-6 devices is fixed, limiting use of that pin to power-supply tie-off only-not functional control.

FAQ

Can STEVAL-CCA022V1 be used with op-amps not listed in the data brief?

Yes. The board's footprint and routing support any single op-amp in SC70-5, SOT-23-5, SOT-23-6, or SC70-6 packages, provided pin functions align with the board's VCCP/VCCN, IN+/IN−, and OUT assignments. Users must verify pin mapping against the target device's datasheet before mounting.

Does the board support single-supply op-amp operation?

Yes, but requires external modification: VCCN must be tied to ground or a reference voltage, and input/output DC biasing must be adjusted manually using the Z-pads and C1/C3 coupling caps. The default design assumes dual-supply operation.

Why is the standby pin unusable for SOT-23-6/SC70-6 devices?

On SOT-23-6 and SC70-6 op-amps, the standby (or shutdown) pin is hardwired to VCC+ on the board. This prevents active control of the pin-users cannot assert logic-low to disable the device. It remains powered continuously during evaluation.

Are passive components included with the board?

No. The board ships unpopulated except for two 4.7 µF decoupling capacitors (C2, C4) and two 10 nF AC-coupling capacitors (C1, C3). All resistors, feedback capacitors, and compensation networks must be added by the user per desired configuration.
