9.2.1.2 Detailed Design Procedure

Design analysis:

• AC-coupled, high-pass frequency
• Large capacitors require longer start-up time from device power on
• Use 1-µF capacitor to achieve high-pass frequency of approximately 159 Hz
• For high-pass equivalent, use C_IN = 0.5 µF, R_IN = 2 kΩ
  1. Set up input dividers initially for one-half supply (to be in center of acceptable common-mode range).
  2. Adjust either divider slightly upwards or downwards as desired to establish quiescent output condition.
  3. Select coupling capacitors based on lowest expected frequency.
