... Pin Number Function FX009A FX009A LG/ Serial Clock : This external clock pulse input is used to “clock in” the Control Data. See Figure 4, Data Load Timing. This input has an internal 1M pullup resistor Load/Latch : Governs the loading and execution of the control data. During serial data loading this input should be kept at a logical '0' to ensure that data rippling past the latches has no effect ...

... A noisy or badly regulated power supply can cause instability and/or variance of selected gains. (b) Care should be taken on the design and layout of the printed circuit board. (c) All external components (Figure 2) should be kept close to the FX009A package. (d) Inputs and outputs should be screened wherever possible. (e) Tracks should be kept short. SINAD (dB) 60 ...

... The gain of each amplifier block (Channel 1 to Channel 8) in the FX009A is set by a separate 8-bit data word ( bit 7 to bit 0 ). This 8-bit word, consisting of 4 Address bits (bit 7 to bit 4) and 4 Gain Control bits (bit 3 to bit 0), is loaded to the Control Data Input in serial format using the external data clock ...
