CA3420EZ - Renesas Electronics

Description: The CA3420 is an integrated circuit operational amplifier that combines PMOS transistors and bipolar transistors on a single monolithic chip. The CA3420 BiMOS operational amplifier features gate protected PMOS transistors in the input circuit to provide very high input impedance, very low input currents (less than 1pA). The internal bootstrapping network features a unique guardbanding technique for reducing the doubling of leakage current for every 10oC increase in temperature. The CA3420 operates at total

CA3420EZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
  • Use a high-quality, low-ESR capacitor (e.g., 10uF) for power decoupling, and place it as close to the VCC pin as possible. Ensure the power supply is stable and regulated, with a minimum of 3.0V and a maximum of 5.5V.
  • The recommended clock frequency is 32.768 kHz, but the device can operate with a clock frequency range of 30 kHz to 100 kHz. However, the accuracy and stability of the clock source will affect the overall performance of the device.
  • To minimize power consumption, set the device to sleep mode when not in use. Use the power-down mode (PD pin) to reduce power consumption to approximately 1.5 μA. Additionally, adjust the clock frequency and voltage regulator settings to optimize power consumption.
  • The maximum allowed capacitance for the crystal oscillator is 20 pF. Exceeding this value may affect the oscillator's stability and accuracy.
