Jurr Is this time also fix. Used with Clock IN pin when internal clock source is used. As shown in the typical circuit, ADC can be interfaced with any microcontroller. Dataasheet am also including CS signal to give you a clear picture. Arduino based GPS receiver. How reliable is it?

DC and AC electrical specif cations do not apply when operating the device beyond its specified operating conditions Note 2: All voltages are measured with respect to gnc, unless otherwise specified. The separate a gnd point should always be wired to the D Gnd Note 3: A zener diode exists, internally, from Voc to gnd and has a typical breakdown voltage of 7 voc.
Two on-chip diodes are tied 10 each analog input see block diagram which will forward conduct for analog input voltages one dice drop below ground or one diode drop greater than the voc supply. Be careful. The spec allows 50 mV forward blas of either diode. This means that as long as the analog vin does not exceed the supply voltage by more than code will be correct. To achieve an absolute 0 Vpc to 5 Voc input voltage range will therefore require a minimum supply voltage of 4. Note 5: Accuracy is guaranteed at fcLK kHz.
At higher clock frequencies accuracy can degrade For lower clock frequencies the duty cyc e limits can be extended so long as the minimum clock high time interval or minimum clock low tim interval is no less than ns.
Note 6: With an asynchronous start pulse, up to a clock periods may be required before the interral clock phases are proper to start the conversion process. To obtain zero code at other analog input voltages see section 2. Absolute with a 2.
