ADA4523-1是一款高电压、低噪声、零漂移运算放大器，可在4.5 V至36 V宽电源范围内提供精密直流性能。失调电压和1/f噪声得到抑制，使该放大器能够实现最大±4 µV的失调电压以及88 nV p-p（典型值）的0.1 Hz至10 Hz输入噪声电压。ADA4523-1的自校准电路在0.01 µV/°C（最大值）温度下具有低失调电压漂移以及随时间而变化的零点漂移。此外，ADA4523-1利用片内滤波实现较高的抗电磁干扰(EMI)能力。
宽电源范围与低噪声、低失调、168 dB电源抑制比(PSRR)和160 dB共模抑制比(CMRR)相结合，使ADA4523-1非常适合高动态范围测试、测量和仪器仪表系统。

EVAL-ADA4523-1
Evaluating the ADA4523-1 36 V, Low Noise, Zero Drift, Operational Amplifier
产品详情
The EVAL-ADA4523-1BRMZ allows the evaluation of the ADA4523-1 single-channel, 8‑lead, micro small outline package (MSOP) operational amplifier. The ADA4523-1 in this evaluation board is configured as a noninverting amplifier with a gain of 101. The ADA4523-1 has a typical gain bandwidth product of 4 MHz. When using a gain of 101, the useable bandwidth of the ADA4523-1 is limited to approximately 39.6 kHz. This limitation in bandwidth acts as a low-pass filter that rejects the artifacts generated by the 330 kHz internal chopping frequency of the ADA4523-1.
The EVAL-ADA4523-1BRMZ layout lessens the thermocouple effects of the trace and components that introduce offset voltages greater than the maximum offset voltage of the ADA4523-1 by carefully constructing the nodes connected to the inverting and noninverting inputs. The ADA4523-1 also features a shutdown mode for low power applications. Test point provisions for the SD and SD_COM pins are placed on the EVAL-ADA4523-1BRMZ to easily use the shutdown function.
The EVAL-ADA4523-1BRMZ mainly consists of 0805 sized resistors and capacitors to ensure simple installation except for the bypass capacitors. The 10 μF bypass capacitors (C1 and C4) have a 2220 package size to accommodate a higher voltage rating because the ADA4523-1 has a maximum supply of 55 V.
For full details on the ADA4523-1, see the ADA4523-1 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADA4523-1BRMZ.

产品详情
The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6 kW charging cable solution, providing a reference design intended for evaluation and prototyping of electric vehicle (EV) charging systems.
The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6 mA DC / 30 mA rms RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available.
A MAX32655 low-power, ARM® Cortex®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.
The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug.
The system is designed to comply with the IEC61851 and IEC62752 standards.
