Notes:
1. Not including any current drawn from the device pins by external circuitry.
2. Enable input at VSS, CSN input at VDD.
3. IRQN pin, D0 to D3 pins.
4. Small signal impedance over the frequency range 100Hz to 2300Hz and at 5.0V.
5. Input signal level is multiplied by the voltage gain (-R2/R1). The overall signal should be
larger than 250mVp-p, at VDD = 5.0V, scale signal for different VDD.
6. Open loop, small signal low frequency measurements.
7. Timing for an external input to the XTAL/CLOCK pin.
