【Current Sense Amplifier Evaluation Board】

Current sensing is fundamental to power management, motor control, and circuit protection. Renesas' current sense amplifier evaluation boards, such as the ISL28130ISENSEV1Z, are optimized to simplify the design of high-performance current measurement circuits.

Core Features and Benefits:

Wide Voltage Adaptability and Flexibility: Supporting single-supply (1.8V to 5.5V) or dual-supply (±0.9V to ±2.75V) operation, this evaluation board easily adapts to diverse voltage environments ranging from portable devices to industrial systems.

Full-Swing Output: Its single-ended full-swing output ensures full utilization of dynamic range across the supply voltage range, delivering high-precision detection signals.

Out-of-the-Box Evaluation Platform: All necessary components and test points are onboard, allowing engineers to quickly connect the load under test, power supply, and measurement instruments. This enables direct evaluation of the ISL28130 chip's key performance metrics—such as bandwidth (400kHz), slew rate (0.2V/µs), and linearity at different currents—without requiring custom PCB design.

【Operational Amplifier Evaluation Board】

Operational amplifiers are the most versatile building blocks in analog circuits. Renesas' op-amp evaluation boards, such as the ISL28191EVAL1Z for the ultra-low-noise ISL28191, provide an ideal platform for evaluating high-precision signal conditioning solutions.

Core Features and Benefits:

Dual-Supply Configuration Support: The board design enables operation with either a single supply (+3V to +5.5V) or separate supplies (±1.5V to ±2.75V), providing negative voltage swing for AC signal processing and facilitating evaluation under real-world conditions.

Focused Performance Evaluation: The ISL28191 emphasizes “ultra-low noise, low distortion, and rail-to-rail output.” The evaluation board enables engineers to directly validate these parameters critical for audio and precision sensor interfaces, such as Total Harmonic Distortion (THD) and input voltage noise density.

Clear Circuit Configuration: Evaluation boards are typically pre-configured for standard inverting/non-inverting amplifier circuits with clearly defined gain settings. Users can flexibly replace feedback network components as needed to test stability and performance across different configurations.

【Instrumentation Amplifier Evaluation Boards】

Instrumentation amplifiers are indispensable for differential signal measurements involving high common-mode voltages, such as in bridge sensors and medical equipment. Renesas' ISL2853xEV2Z and ISL2863xEV2Z evaluation boards are designed for its high-precision, programmable gain instrumentation amplifier (PGA) series.

Core Features and Advantages:

Exceptional DC Accuracy: The evaluation board demonstrates the chip's “zero offset” and ultra-low input bias voltage (maximum 5μV) characteristics, critical for devices measuring minute DC signals like load cells and pressure transducers.

High Common-Mode Rejection Ratio (CMRR): The evaluation board enables measurement of the chip's CMRR up to 138dB at gain G=100, validating its effective signal extraction capability in industrial environments with strong noise interference.

Flexible Programmable Gain: The board supports pin-configurable gain settings up to 9 levels (from 1 to 1000), enabling users to rapidly test bandwidth (gain bandwidth 2.3MHz), noise (0.4μV peak), and linearity performance at different amplification levels to identify the optimal sensor interface matching point.
