STMicroelectronics STEVAL-CCA057V2

Overview

STEVAL-CCA057V2 from STMicroelectronics is a bare evaluation board designed for rapid prototyping of dual operational amplifiers in MSO8 (SOIC-8) package, supporting configurations including Sallen-Key filters, instrumentation amplifiers, transimpedance amplifiers, and AC-coupled circuits. It features 50 Ω input impedance tracks, dual decoupling capacitor networks (1 µF/10 µF + optional 100 pF), and configurable power routing for single- or dual-supply operation.

For engineers reviewing the STEVAL-CCA057V2 datasheet, STEVAL-CCA057V2 pinout, STEVAL-CCA057V2 application, or STEVAL-CCA057V2 equivalent, this page delivers verified layout details, supported op amp compatibility, measurement-ready signal paths, and configuration-specific jumper guidance - all validated against ST's AN4574 application note.

Technical Context

The board implements a universal dual-op-amp test platform with independent signal routing for both amplifiers (IC1A and IC1B), each accessible via dedicated SMB connectors or test points for VINA±, VINB±, VOUTA, VOUTB, VREF, and supply pins. All passive component footprints (R, C) follow 1206 size standards and support reworkable soldering.

Power delivery supports flexible biasing: dual-supply mode requires 0 Ω links on CIN_VCCN_ON/CIN_VCCP_ON; single-supply mode shorts VCCN to GND via C3/C4. Output loading options include RL_A/RL_B and CL_A/CL_B footprints for anti-alias filtering or bandwidth limiting - with explicit design warnings against oscillation due to capacitive loading.

FAQ

Does STEVAL-CCA057V2 include an operational amplifier?

No. The board is supplied bare - without any op amp, resistors, or capacitors soldered. Users must separately procure and mount a compatible dual op amp in MSO8/SOIC-8 package (e.g., LM358ST, TSV912IST) along with required external components per target configuration.

Which op amp packages are supported?

Only MSO8 (ST's designation for SOIC-8) packages are mechanically and electrically supported. The board's footprint matches standard SOIC-8 pitch (1.27 mm), pad dimensions, and thermal pad absence - verified against Figure 1 (MSO8 pinout) in AN4574.

Can STEVAL-CCA057V2 be used for single-supply op amp testing?

Yes. Single-supply operation is enabled by shorting VCCN to GND using C3 or C4 jumpers, setting VCCP as the positive rail. Power sequencing and decoupling remain valid per AN4574 Section 1.4, with recommended 1 µF/10 µF bulk caps and optional 100 pF local caps.

What connector types are used for signal I/O?

VINA+, VINA−, VINB+, VINB−, VOUTA, and VOUTB support either female SMB coaxial connectors or surface-mount test points (PT_VOUT_A, PT_VOUT_B, etc.). SMB connectors provide 50 Ω impedance-matched connections; test points allow direct probe access with minimal parasitic loading.
