4 / 8 page AD9000 –4– REV. A WARNING! ESD SENSITIVE DEVICE CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9000 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

PIN DESIGNATIONS PIN DESCRIPTIONS Pin Name Description –VS Negative supply terminal, nominally –5.2 V. ANALOG GROUND Analog ground return. All grounds should be connected together near the AD9000. VH The hysteresis control voltage varies the comparator hysteresis from 15 mV to 50 mV, for a change of 0 V to +3 V at the hysteresis control pin. ENCODE The ENCODE pin controls the conversion cycle. Encode is rising edge sensitive and should be driven with a 50% duty-cycle waveform under normal conditions. –VREF The most negative reference voltage for the internal resistor ladder. AIN Analog input pin. +VS Positive supply terminal, nominally +5.0 V. +VREF Most positive reference voltage of the internal resistor ladder. BIT 6 (LSB) One of six digital outputs. BIT 6 (LSB) is the least-significant-bit of the digital output. BIT 5 – BIT 2 One of six digital outputs. BIT 1 (MSB) One of six digital outputs. BIT 1 (MSB) is the most-significant-bit of the digital output. OVERFLOW Overflow data output. Logic high indicates an input overvoltage (AIN ≥ +VREF). DIGITAL GROUND Digital ground return. All grounds should be connected together near the AD9000. |
