AD2S80ABD

Overview

The AD2S80ABD is a monolithic tracking resolver-to-digital converter manufactured on a BiMOS II process. It converts analog resolver signals into a parallel natural binary digital word using ratiometric conversion, ensuring high noise immunity and tolerance to lead length variations. The device supports user-selectable resolutions of 10, 12, 14, or 16 bits via SC1 and SC2 pins. It operates with supply voltages of ±10.8 V to ±13.2 V and logic voltage +VL of +5 V to +13.2 V. The industrial temperature grade (AD/BD suffix) functions between -40°C and +85°C. Key outputs include 16-bit position data, an analog velocity signal, and control flags such as BUSY, DIRECTION, and RIPPLE CLOCK.

Feature Summary

Monolithic BiMOS II construction in a 40-lead DIP package
User-selectable resolution: 10, 12, 14, or 16 bits
Ratiometric tracking conversion for high noise immunity
Analog velocity output proportional to rotation speed
Industrial temperature range (-40°C to +85°C)

Applications

DC Brushless and AC Motor Control
Process Control Systems
Numerical Control of Machine Tools
Robotics Axis Control
Military Servo Control

Procurement Notes

Verify the ordering suffix 'BD' confirms the Industrial Temperature Range (-40°C to +85°C). Confirm the package type is the 40-lead Ceramic DIP. Ensure power supplies are within ±10.8 V to ±13.2 V. Check that external components for bandwidth and tracking rate selection match the desired resolution setting.

Selection Notes

Select resolution based on required angular accuracy; 16-bit offers highest precision but lower max tracking rate (16.25 rps) compared to 10-bit (1040 rps). Calculate external resistors R4 and R6 according to the chosen bit count to scale integrator and VCO inputs. Ensure reference frequency is between 50 Hz and 20,000 Hz. Verify input signal levels are maintained at 2 V rms ±10% for optimal velocity signal linearity.

Part Context

The AD2S80A series includes variants processed to MIL-STD-883B Class B standards. The 'AD' suffix denotes Industrial Temperature Range, while 'JD', 'KD', 'LD' denote Commercial Range. The 'BD' suffix specifically indicates the Industrial Grade version in the 40-lead DIP package. Other packages include the 44-terminal LCC (E suffix).
