AD2S80AKD

Overview

The AD2S80AKD is a monolithic resolver-to-digital converter manufactured on a BiMOS II process, housed in a 40-lead DIP package. It provides user-selectable resolution of 10, 12, 14, or 16 bits via SC1 and SC2 pins. The device operates with ±12 V analog supplies and +5 V logic supply, consuming typically 300 mW. It supports reference frequencies from 50 Hz to 20,000 Hz. Angular accuracy is specified at +1 LSB for the A-grade variant. Maximum tracking rates vary by resolution: 1040 rps at 10-bit, decreasing to 16.25 rps at 16-bit. The commercial temperature range version (KD suffix) operates between 0°C and 70°C.

Feature Summary

User-selectable resolution (10, 12, 14, or 16 bits) via SC1/SC2 control pins
Ratiometric tracking conversion providing high noise immunity and tolerance to lead length
Analog velocity output proportional to rotation speed, replacing tachogenerators
Three-state digital outputs compatible with 8-bit and 16-bit data buses

Applications

DC brushless and AC motor control systems
Numerical control of machine tools
Robotics axis control
Military servo control applications

Procurement Notes

Verify the KD suffix confirms the commercial temperature grade (0°C to 70°C). Ensure the ordering code matches the 40-lead DIP package configuration. Confirm that the specific revision level meets system requirements, as specifications are subject to change without notice. Cross-reference pinout compatibility if integrating into existing designs.

Selection Notes

Select external components R4 and R6 based on the chosen resolution and desired maximum tracking rate. Ensure the reference frequency to bandwidth ratio adheres to guidelines for the selected bit depth. Use preferred value resistors and capacitors with 5% tolerance to maintain performance. Verify power supply decoupling with 100 nF ceramic and 10 µF tantalum capacitors near the device.

Part Context

The AD2S80A series includes variants such as AD2S80AJD (Industrial), AD2S80ASD (Extended), and AD2S80AE (LCC Package). The AD2S80AKD specifically denotes the commercial temperature range version in the standard 40-lead DIP package. Other models like AD2S82 offer different pin counts and resolutions.
