Philips Semiconductors
Notes
1. Assumes use of external components as shown in the application diagram (Figs 38 or 39).
2. Highest clock frequency at which data slicer produces 1010 output in analog self-test mode.
3. The maximum input current depends on the value of the external resistor connected to I
4. V
5. Measuring bandwidth: 200 Hz to 20 kHz, f
6. f
7. Gain of the ADC is defined as G

a) Digital output = the number of pulses at the digital output in counts/s and I
b) The maximum input current depends on R
c) The gain tolerance is the deviation from the calculated gain.
