Notes:
1. At VDD = 5.0V only. Signal levels or currents are proportional to VDD.
2. Not including any current drawn from the device pins by external circuitry.
3. IRQN pin.
4. Timing for an external input to the XTAL/CLOCK pin.
5. With input gain components set as recommended in Figure 2.
6. See filter response (Figure 5).
7. Small signal impedance VDD = 5.0V and Tamb=25°C. A minimum load resistance of
6kΩ is suggested.
