CA5420AMZ - Renesas Electronics

Description: The CA5420A is an integrated circuit operational amplifier that combines PMOS transistors and bipolar transistors on a single monolithic chip. It is designed and guaranteed to operate in microprocessor logic systems that use V+ = 5V, V- = GND, since it can operate down to ±1V supplies. It will also be suitable for 3. 3V logic systems. The CA5420A BiMOS operational amplifier features gate-protected PMOS transistors in the input circuit to provide very high input impedance, very low input currents (less than

CA5420AMZ 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 grounds separate and connect them at a single point. Use short, direct traces for the input and output signals, and avoid routing signals under the device.
  • Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) for power supply decoupling, placed as close as possible to the device. Ensure the power supply voltage is within the recommended range (2.7V to 5.5V) and use a low-dropout regulator if necessary.
  • The recommended input signal range is 0.5V to 3.5V, with a maximum input voltage of 4.5V. Signals outside this range may not be accurately amplified or may cause device damage.
  • The gain of the CA5420AMZ can be configured using external resistors (Rf and Rg) connected between the output and the inverting input. The gain is calculated as (Rf/Rg) + 1. Ensure the resistors are of high quality and have a low temperature coefficient.
  • The maximum output current of the CA5420AMZ is 30mA. Exceeding this current may cause device damage or reduce its lifespan.
