Doubted for buy this manual as it is my first order here and at not have cover image, I assumed would haven't. However, within 24 hs, already possessed the link to download it. The manual are scanned correctly and have all what is needed. Includes adjustments and diagrams of all circuits. Very satisfied.
Really good quality, Π°ll readable.! Wonderful work shop. I recommend to all!
Good quality service manual.The scheme is on A3 format and very readable.Thank you
Very good service-manual with clear electrical diagrams. Thanks you.
the manual is in quite good quality and it's in pdf. manual was send in less then 6h.

PIN FUNCTION DESCRIPTIONS
Pin No. 1
Description Data Enable Low Input. This port controls the 8-bit parallel data latch and shift register. A Logic 0-to-1 transition transfers the latched data to the attenuator core (updates the gain) and simultaneously inhibits serial data transfer into the register. A 1-to-0 transition inhibits the data latch (holds the previous gain state) and simultaneously enables the register for serial data load. Serial Data Input. This digital input allows for an 8-bit serial (gain) word to be loaded into the internal register with the MSB (Most Significant Bit) first. Clock Input. The clock port controls the serial attenuator data transfer rate to the 8-bit masterslave register. A Logic 0-to-1 transition latches the data bit and a 1-to-0 transfers the data bit to the slave. This requires the input serial data word to be valid at or before this clock transition. Common External Ground Reference.

Common Positive External Supply Voltage. A 0.1 F capacitor must decouple each pin. Logic â0â powers down the part. Logic â1â powers up the part. Low Power Sleep Mode. In the Sleep mode, the AD8323âs supply current is reduced to 4 mA. A Logic â0â powers down the part (High Z OUT State) and a Logic â1â powers up the part. Negative Output Signal. Positive Output Signal. Internal Bypass. This pin must be externally ac-coupled (0.1 F cap). Noninverting Input. DC-biased to approximately V CC /2. For single-ended inverting operation, use a 0.1 F decoupling capacitor and a 39.2 resistor between V and ground. IN+ Inverting Input. DC-biased to approximately V CC /2. Should be ac-coupled with a 0.1 F capacitor.
