The ADA4523-1 is a high voltage, low noise, zero drift op amp that offers precision dc performance over a wide supply range of 4.5 V to 36 V. Offset voltage and 1/f noise are suppressed, allowing this op amp to achieve a maximum offset voltage of ±4 µV and a 0.1 Hz to 10 Hz input noise voltage of 88 nV p-p typical.The self calibrating circuitry of the ADA4523-1 results in low offset voltage drift with temperature (0.01 µV/°C maximum) and zero drift over time. Additionally, the ADA4523-1 uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI).

Wide supply range, combined with low noise, low offset, 168 dB power supply rejection ratio (PSRR), and 160 dB common-mode rejection ratio (CMRR), make the ADA4523-1 well suited for high dynamic range test, measurement, and instrumentation systems. 

Applications

  • High resolution data acquisition
  • Reference buffering
  • Test and measurement
  • Electronic scales
  • Thermocouple amplifiers
  • Strain gages
  • Low-side current sense

Product Detail

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.

Product Detail

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.
