STMicroelectronics STEVAL-CCA057V3

Overview

STEVAL-CCA057V3 from STMicroelectronics is a bare evaluation board designed for rapid prototyping of dual operational amplifiers in MSO10 (10-pin mini-SO) package, supporting configurations including Sallen-Key filters, instrumentation amplifiers, transimpedance stages, and AC-coupled circuits with 50 Ω input impedance matching and dual decoupling capacitor networks (1 µF + 10 µF per supply rail).

For engineers reviewing the STEVAL-CCA057V3 datasheet, STEVAL-CCA057V3 pinout, STEVAL-CCA057V3 application, or STEVAL-CCA057V3 equivalent, this board enables on-board characterization of ST dual op amps prior to final PCB integration-especially where flexible gain, bandwidth, and stability validation across low-pass, high-pass, differential, and photodiode interface topologies are required.

Technical Context

The board implements a dual-channel, surface-mount layout optimized for MSO10-packaged dual op amps, with independent power rails (VCCP/VCCN), dedicated standby control pins (StbyA/StbyB), and configurable input/output paths via 0 Ω jumpers and open pads. It supports both dual-supply and single-supply operation via C3/C4 bridging.

All signal paths-including VINA±, VINB±, VOUTA, VOUTB, and reference nodes (VREFA±, VREFB±)-are routed with controlled 50 Ω characteristic impedance for square-wave integrity testing. Decoupling includes discrete 100 pF capacitors (CAPVCCN/CAPVCCP) near IC power pins for high-frequency noise rejection.

FAQ

Is an operational amplifier included with the STEVAL-CCA057V3 board?

No. The STEVAL-CCA057V3 is a bare board-no op amp, resistors, or capacitors are soldered or supplied. Users must separately select and mount a compatible dual op amp in MSO10 package (e.g., TSV623IST or LMV823IST) along with required external components per target configuration.

Which op amp packages does the board support?

The board supports only the MSO10 (10-pin mini-SO) package, as confirmed by its footprint, pin spacing, and mechanical layout in AN4575. It is not compatible with SO8, TSSOP, or DFN variants-even if functionally similar-due to physical pad alignment and thermal pad absence.

Can the board be used with single-supply op amps?

Yes. Single-supply operation is enabled by shorting the negative rail (VCCN) to ground via 0 Ω jumper on C3 or C4, reconfiguring power delivery between VCCP and GND. All biasing networks (e.g., VREFA±, VREFB±) remain configurable for rail-to-rail or mid-supply referencing.

What is the purpose of the 50 Ω resistors (R50_1A, R50_2A, etc.)?

These 50 Ω resistors provide impedance matching at the input nodes (VINA±, VINB±) to preserve signal integrity when driven by 50 Ω sources-critical for accurate settling time, overshoot, and frequency response measurements per op amp datasheet test conditions.
