STMicroelectronics STEVAL-CCA057V4

Overview

STEVAL-CCA057V4 from STMicroelectronics is a bare evaluation board designed for rapid prototyping of dual operational amplifiers in DFN8 (2 × 2 mm, exposed pad) packages. It supports voltage follower, inverting/non-inverting amplifier, Sallen-Key low/high-pass filters, instrumentation amplifier, transimpedance, and AC-coupled configurations. The board features 1206-footprint resistors/capacitors, dual decoupling networks (1 µF + 10 µF per supply rail), and 50 Ω input impedance tracks for signal integrity.

For engineers reviewing the STEVAL-CCA057V4 datasheet, STEVAL-CCA057V4 pinout, STEVAL-CCA057V4 application, or STEVAL-CCA057V4 equivalent, this page delivers verified layout details, configuration wiring guidance, power supply decoupling best practices, and real-world op amp circuit validation methods - all specific to dual-channel DFN8 op amps used in precision analog signal conditioning.

Technical Context

The board implements a universal dual-op-amp test platform with independent power rails (VCCP/VCCN), configurable input reference points (VREFA±/VREFB±), and output loading options (RL_A/CL_A, RL_B/CL_B). All critical nodes - VINA±, VINB±, VOUTA, VOUTB - support SMB connectors or test points for oscilloscope probing.

It enables on-board characterization prior to integration of ST's dual op amps, including rail-to-rail (TSV912IQ2T), micropower (TSV632IQ2T), zero-drift (TSZ122IQ2T), and high-merit-factor (TSV522IQ2T) devices. Layout includes dedicated ground planes on both layers and thermal relief for the DFN8 exposed pad.

FAQ

Does STEVAL-CCA057V4 include an operational amplifier?

No. The board is a bare PCB with no active components soldered. Users must separately procure and mount a compatible dual op amp in DFN8 (2 × 2 mm, exposed pad) package - such as TSV912IQ2T, LM2904IQ2T, or TSZ122IQ2T - based on their gain, bandwidth, and supply requirements.

How do I configure the board for single-supply operation?

Bridge C3 or C4 with a 0 Ω resistor to short VCCN to GND, establishing a single supply between VCCP and ground. Ensure input common-mode range and output swing of the selected op amp are compatible with this configuration, and verify reference biasing (e.g., VREFA+/VREFA−) accordingly.

What is the purpose of the R50_1A/R50_2A and R50_1B/R50_2B resistors?

These 50 Ω footprints enable precise input impedance matching on VINA± and VINB± traces. When populated, they ensure minimal signal reflection during high-speed transient measurements (e.g., settling time, overshoot), preserving waveform integrity when using 50 Ω test equipment.

Can I cascade multiple STEVAL-CCA057V4 boards?

Yes. The board supports cascaded configurations - for example, connecting VOUT_A to VINB+ of a second board - enabling multi-stage filtering (e.g., 8th-order Sallen-Key), composite gain stages, or differential-to-single-ended conversion without custom layout effort.
