... Both models feature excellent dynamic performance including a typical SNR of 72dB for the ADS-230 and 70dB for the ADS-231. The ADS-230 and ADS-231 are packaged in a small 44-pin plastic Leaded Chip Carrier (LCC). Each model contains a ...

... ADS-230/ADS-231 These are the analog and digital power supply input pins. They should all be connected the same voltage source. Both AV DGNDD. Bypass using a 0.1µF ceramic capacitor in parallel with a 10µF tantalum capacitor. AGND, DGNDC, DGNDD These are the analog and digital ground pins. All of the ground pins should be returned to the same potential and connected to a stable, noise-free system ground ...

... The bandwidth of the input circuit is: F (–3dB) = 1/[ MUX Internal Multiplexer Both the ADS-230 and ADS-231 have an internal multiplexer that is controlled by the logic level on the SEL pin when EOC goes low. See the timing diagrams. The MUX setup and hold times can be determined from the following – ...

... S/H Input The clock source driving the S/H input must be free of jitter. For best performance, a crystal oscillator is recommended. For the ADS-230 and ADS-231, a 1.0 and 1.5Mhz square wave will provide a good signal for the respective S/H inputs. In both cases, as long as the duty cycle is near 50%, the S/H pulse widths fall under the maximum allowed. ...
