LT6656ACS6-5#TRMPBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT6656ACS6-5 involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths to reduce noise and parasitic inductance. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure stability, make sure to follow the recommended capacitor values and types, and keep the output capacitor ESR within the recommended range. Also, avoid using capacitors with high ESL or ESR, and keep the feedback loop impedance low. Additionally, a small series resistor (e.g., 1-10 ohms) can be added to the output to improve stability.
  • The maximum output current capability of the LT6656ACS6-5 is 20mA, but it can be limited by the thermal performance of the package and the PCB. It's recommended to derate the output current based on the ambient temperature and the thermal resistance of the package and PCB.
  • Yes, the LT6656ACS6-5 can be used as a voltage reference for an ADC or DAC, but it's essential to consider the noise and drift specifications of the device. The LT6656ACS6-5 has a low noise output (typically 10uVrms), but it may not be suitable for high-resolution or high-speed converters. Additionally, the output voltage may drift over time and temperature, so it's recommended to use a more precise voltage reference if high accuracy is required.
  • The power dissipation of the LT6656ACS6-5 can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. The maximum power dissipation is limited by the package thermal resistance and the ambient temperature.
