3 / 5 page ADC-304 ® ® 6. The analog input signal is sampled on the positive-going edge of CLOCK. Corresponding digital data appears at the output on the negative-going edge of the CLOCK pulse after a brief delay of 31ns maximum (TDLH, TDHL). Refer to the Timing Diagram (Figure 3) for more information. 7. Connect all free pins to ANALOG GND to reduce unwanted noise. The analog input range is equal to a 2V spread. The voltage on VT-VB will equal 2V. The connection of VT and ANALOG GND is 2V higher than VB. Whether using a single or dual power supply, the analog input will range from the value of VT to VB. If VT equals +5V, then VB will equal +3V and the analog input range will be from +3 to +5V. 4. The voltage between VT and VB is equivalent to the dynamic range of the analog input. Bypass VB to ANALOG GND USING a 1µF and a 0.01µF capacitor in parallel. To balance the characteristics of the ADC-304 at high frequencies, bypass VM with a 0.01µF capacitor to ANALOG GND. Also, VM can be used as a trimming pin for more precise linearity compensation. A stable voltage source with a potential equal to VB and a 1k Ω potentiometer can be connected to VM as shown in Figure 2 for this purpose. 5. Separate the clock input, CLOCK, from other leads as much as possible, observing proper EMI and RFI wiring techniques. This reduces the inductive pick-up of this lead from interfering with the “clean” operation of the ADC-304. Figure 3. ADC-304 Timing Diagram Figure 2.
