ISL26134AVZ - Renesas Electronics

Description: The ISL26132 and ISL26134 are complete analog front ends for high resolution measurement applications. These 24-bit Delta-Sigma Analog-to-Digital Converters include a very low-noise amplifier and are available as either two or four differential multiplexer inputs. The devices offer the same pinout as the ADS1232 and ADS1234 devices and are functionally compatible with these devices. The ISL26132 and ISL26134 offer improved noise performance at 10Sps and 80Sps conversion rates. The on-chip low-noise programm

ISL26134AVZ Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for optimal performance. Renesas recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital sections separate. Additionally, use short and wide traces for power and ground connections, and avoid vias under the IC.
  • To ensure accurate voltage measurement, use a high-precision voltage reference, and ensure the input voltage is within the specified range. Also, use a low-noise, low-impedance power supply, and minimize noise coupling into the input pins.
  • The maximum allowed capacitance on the output pins is 100nF. Exceeding this value may cause instability or oscillations in the output voltage.
  • The ISL26134AVZ is rated for operation up to 125°C. However, the device's performance and accuracy may degrade at high temperatures. It's essential to consider the thermal design and ensure proper heat dissipation to maintain reliable operation.
  • To troubleshoot issues, start by verifying the power supply and input voltage. Check for proper PCB layout, decoupling, and noise reduction. Use an oscilloscope to monitor the output voltage and input signals. Consult the datasheet and application notes for guidance on specific issues.
