Pin Descriptions Pin No. Mnemonic Function 1 (AD7475) REF IN Reference Input for the AD7475. An external reference must be applied to this input. The voltage range for the external reference is 2.5 V ± 1% for specified performance. A cap of a least 0.1 μF should be placed on the REF IN pin. 1 (AD7495) REF OUT Reference Output for the AD7495. A minimum 100 nF capacitance is required from this pin to GND. The internal reference can be taken from this pin, but buffering is required before it is applied elsewhere in a system. 2 VIN Analog Input. Single-ended analog input channel. The input range is 0 to REF IN. 3 GND Analog Ground. Ground reference point for all circuitry on the AD7475/AD7495. All analog input signals and any external reference signal should be referred to this GND voltage. 4 SCLK Serial Clock, Logic Input. SCLK provides the serial clock for accessing data from the part. This clock input is also used as the clock source for the AD7475/AD7495 conversion process. 5 SDATA Data Out, Logic Output. The conversion result from the AD7475/AD7495 is provided on this output as a serial data stream. The bits are clocked out on the falling edge of the SCLK input. The data stream consists of four leading zeros followed by the 12 bits of conversion data, which is provided MSB first. 6 VDRIVE Logic Power Supply Input. The voltage supplied at this pin determines the operating voltage for the serial interface of the AD7475/AD7495. 7 CS Chip Select, Active Low Logic Input. This input provides the dual function of initiating conversions on the AD7475/AD7495 and also frames the serial data transfer. 8 VDD Power Supply Input. The VDD range for the AD7475/AD7495 is from 2.7 V to 5.25 V. |
