AD2S80AUD

The AD2S80AUD is a high-precision resolver-to-digital converter (RDC) from Analog Devices. It converts the analog outputs of a resolver (sin/cos signals) into a digital representation of the shaft angle and velocity.
### Key Features:
- 12-bit resolution for accurate angle measurement.
- Tracking rate up to 1,000 rps for high-speed applications.
- On-board excitation oscillator (10 kHz typical) for resolver drive.
- Serial and parallel output options for flexible interfacing.
- Robust noise immunity due to synchronous demodulation.
### Applications:
- Motor control (servo, BLDC)
- Aerospace & defense systems
- Industrial automation
The AD2S80AUD is designed for reliability in harsh environments, making it suitable for demanding motion control applications.

The AD2S80AUD is a resolver-to-digital converter with a 44-pin package (PLCC or LCC). Key functions include:
- Resolver Interface: Excitation output (EXC, EXC) and inputs (SIN, SINLO, COS, COSLO) for resolver signals.
- Digital Output: 10, 12, 14, or 16-bit parallel data (D0–D15) with a latch enable (LE) for position/velocity data.
- Control Pins: Includes chip select (CS), read (RD), and sample rate control (RDC).
- Power Supply: Typically ±5V for analog/digital sections.
- Reference Oscillator: External or internal clock option (CLKIN, CLKOUT).
It converts resolver signals to digital position/velocity data, widely used in motion control systems.

The AD2S80AUD is manufactured by Analog Devices, Inc. (ADI), a leading American multinational semiconductor company specializing in data conversion, signal processing, and power management technologies. Founded in 1965, ADI is known for its high-performance analog, mixed-signal, and digital signal processing (DSP) integrated circuits (ICs). The AD2S80AUD is a resolver-to-digital converter, reflecting ADI's expertise in precision sensing and motion control applications. The company serves industries like automotive, industrial, healthcare, and communications.

The AD2S80AUD is available in a 28-lead ceramic dual in-line package (CERDIP). This package type is designed for high-reliability applications, offering robust performance in harsh environments. The CERDIP construction ensures excellent thermal and mechanical stability, making it suitable for military and industrial uses. The package is hermetically sealed to protect against moisture and contaminants.
