REF198GSZ Frequently Asked Questions (FAQs)

  • The REF198GSZ is a sensitive device and requires careful layout and placement to minimize noise and ensure accurate performance. It's recommended to place the device close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC), and to use a solid ground plane to reduce noise. Additionally, it's recommended to use a low-ESR capacitor (e.g., 10uF) between the VOUT pin and GND to filter out high-frequency noise.
  • To ensure stability and accuracy over temperature, it's recommended to use a high-quality, low-temperature-coefficient (TC) resistor (e.g., 1kΩ, 0.1%) in the output divider network. Additionally, it's recommended to use a thermally stable voltage reference, such as the REF198GSZ, which has a specified temperature coefficient of ±10ppm/°C.
  • The recommended output capacitor value for the REF198GSZ is 10uF to 22uF, with a low equivalent series resistance (ESR) to minimize noise and ensure stability. A larger capacitor value can be used, but it may increase the startup time and reduce the power supply rejection ratio (PSRR).
  • Yes, the REF198GSZ is suitable for use as a voltage reference for ADCs or DACs. It provides a stable and accurate voltage reference, which is essential for maintaining the accuracy and linearity of the converter. However, it's recommended to consult the datasheet and application notes for specific guidance on using the REF198GSZ with ADCs or DACs.
  • The output voltage of the REF198GSZ can be calculated using the following formula: VOUT = (R1 / (R1 + R2)) * VREF, where R1 and R2 are the resistors in the output divider network, and VREF is the internal voltage reference (2.048V for the REF198GSZ).
