AD2S1210Variable Resolution, 10-Bit to 16-Bit R/D Converter with Reference Oscillator | Development Boards, Kits, Programmers | 9 | Active | The AD2S1210 is a complete 10-bit to 16-bit resolution tracking resolver-to-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers.The converter accepts 3.15 V p-p ± 27% input signals, in the range of 2 kHz to 20 kHz on the sine and cosine inputs. A Type II servo loop is employed to track the inputs and convert the input sine and cosine information into a digital representation of the input angle and velocity. The maximum tracking rate is 3125 rps.The AD2S1210WDSTZ and the AD2S1210WDSTZRL7 models have been approved by an independent accredited body for use in Automotive Safety Integrity Level B rated applications according to ISO 26262. Contact your local Analog Devices, Inc., sales office to obtain a copy of the safety manual and ASIL B safety assessment certificate.PRODUCT HIGHLIGHTSRatiometric tracking conversion. The Type II tracking loop provides continuous output position data without conversion delay. It also provides noise immunity and tolerance of harmonic distortion on the reference and input signals.System fault detection. A fault detection circuit can sense loss of resolver signals, out-of-range input signals, input signal mismatch, or loss of position tracking. The fault detection threshold levels can be individually programmed by the user for optimization within a particular application.Input signal range. The sine and cosine inputs can accept differential input voltages of 3.15 V p-p ± 27%.Programmable excitation frequency. Excitation frequency is easily programmable to a number of standard frequencies between 2 kHz and 20 kHz.Triple format position data. Absolute 10-bit to 16-bit angular position data is accessed via either a 16-bit parallel port or a 4-wire serial interface. Incremental encoder emulation is in standard A-quad-B format with direction output available.Digital velocity output. 10-bit to 16-bit signed digital velocity accessed via either a 16-bit parallel port or a 4-wire serial interface.APPLICATIONSDC and ac servo motor controlEncoder emulationElectric power steeringElectric vehiclesIntegrated starter generators/alternatorsAutomotive motion sensing and control |

AD2S90Low Cost, Complete 12-Bit Resolver-to-Digital Converter | Integrated Circuits (ICs) | 2 | Active | The AD2S90 is a complete 12-bit resolution tracking resolver-to- digital converter. No external components are required to operate the device.The converter accepts 2 V rms ± 10% input signals in the range 3 kHz-20 kHz on the SIN, COS and REF inputs. A Type II servo loop is employed to track the inputs and convert the input SIN and COS information into a digital representation of the input angle. The bandwidth of the converter is set internally at 1 kHz. The maximum tracking rate is 375 rps at 12-bit resolution.Angular position output information is available in two forms, absolute serial binary and incremental A quad B.The absolute serial binary output is 12-bit (1 in 4096). The data output pin is high impedance when Chip SelectCSis logic HI. This allows the connection of multiple converters onto a common bus. Absolute angular information in serial pure binary form is accessed byCSfollowed by the application of an external clock (SCLK) with a maximum rate of 2 MHz.The encoder emulation outputs A, B and NM continuously produce signals equivalent to a 1024 line encoder.When decoded this corresponds to 12-bits resolution. Three common north marker pulse widths are selected via a single pin (NMC).An analog velocity output signal provides a representation of velocity from a rotating resolver shaft traveling in either a clockwise or counterclockwise direction.The AD2S90 operates on a ±5 V dc ± 5% power supplies and is fabricated on Analog Devices' Linear Compatible CMOS process (LC2MOS). LC2MOS is a mixed technology process that combines precision bipolar circuits with low power CMOS logic circuits. |

AD3541RSingle Channel, 12-/16-Bit, 16 MUPS, Multispan, Multi-IO SPI DAC | Integrated Circuits (ICs) | 2 | Active | The AD3541R is a low drift, single channel, ultra-fast, 12-/16-bit accuracy, voltage output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3541R operates with a fixed 2.5 V reference.Each DAC incorporates three drift compensating feedback resistors for the internal transimpedance amplifier (TIA) that scales the output voltage. The device has five preconfigured output voltage ranges: 0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −2.5 V to +7.5 V.The AD3541RBCPZ16 (hereafter referred to as AD3541R-16) can operate in fast mode for maximum speed or precision mode for maximum accuracy. The AD3541RBCPZ12 (hereafter referred to as AD3541R-12) has a single operation mode.The serial peripheral interface (SPI) can be configured in dual SPI and single SPI (classic SPI) mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2 V to 1.8 V.The AD3541R is specified over the extended industrial temperature range (–40°C to +105°C).APPLICATIONSInstrumentationHardware in the loopProcess control equipmentMedical devicesAutomated test equipmentData acquisition systemProgrammable voltage sourcesOptical communications |
