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. IRQ 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.
