The AD2S80A is a monolithic 10-, 12-, 14-, or 16-bit tracking resolver-to-digital converter contained in a 40-lead DIP or 44- terminal LCC ceramic package. It is manufactured on a BiMOS II process that combines the advantages of CMOS logic and bipolar high accuracy linear circuits on the same chip.The converter allows users to select their own resolution and dynamic performance with external components. This allows the users great flexibility in defining the converter that best suits their system requirements. The converter allows users to select the resolution to be 10, 12, 14, or 16 bits and to track resolver signals rotating at up to 1040 revs per second (62,400 rpm) when set to 10-bit resolution.The AD2S80A converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high-noise immunity and tolerance of lead length when the converter is remote from the resolver.The 10-, 12-, 14- or 16-bit output word is in a three-state digital logic available in 2 bytes on the 16 output data lines. BYTE SELECT, ENABLE and INHIBIT pins ensure easy data transfer to 8- and 16-bit data buses, and outputs are provided to allow for cycle or pitch counting in external counters.An analog signal proportional to velocity is also available and can be used to replace a tachogenerator.The AD2S80A operates over 50 Hz to 20,000 Hz reference frequency.APPLICATIONS DC Brushless and AC Motor Control Process Control Numerical Control of Machine Tools Robotics Axis Control Military Servo ControlPRODUCT HIGHLIGHTS Monolithic A one chip solution reduces the package size required and increases the reliability. Resolution Set by User Two control pins are used to select the resolution of the AD2S80A to be 10, 12, 14, or 16 bits allowing the user to use the AD2S80A with the optimum resolution for each application. Ratiometric Tracking Conversion Conversion technique provides continuous output position data without conversion delay and is insensitive to absolute signal levels. It also provides good noise immunity and tolerance to harmonic distortion on the reference and input signals. Dynamic Performance Set by the User By selecting external resistor and capacitor values the user can determine bandwidth, maximum tracking rate and velocity scaling of the converter to match the system requirements. The external components required are all low cost preferred value resistors and capacitors, and the component values are easy to select using the simple instructions given. Velocity Output An analog signal proportional to velocity is available and is linear to typically one percent. This can be used in place of a velocity transducer in many applications to provide loop stabilization in servo controls and velocity feedback data. Low Power Consumption Typically only 300 mW. Military Product The AD2S80A is available processed in accordance with MIL-STD-883B, Class B.
