The AD9831AST is a Direct Digital Synthesizer (DDS) integrated circuit from Analog Devices Inc. It features a 10-bit resolution digital-to-analog converter and operates with a master clock frequency of up to 25 MHz. The device uses a 32-bit tuning word for precise frequency and phase control.
This DDS IC is designed for surface mount assembly and is housed in a 48-LQFP package with a 7x7 mm body size. It supports a wide supply voltage range of 2.97V to 5.5V and is specified for operation over the industrial temperature range of -40°C to 85°C.
The AD9831AST is suitable for applications requiring programmable frequency generation, including signal synthesis and modulation. Its integrated phase accumulator and sine lookup table simplify system design.
The AD9831AST has a resolution of 10 bits.
The maximum master clock frequency is 25 MHz.
The operating temperature range is -40°C to 85°C.
The supply voltage range is 2.97V to 5.5V.
The AD9831AST comes in a 48-LQFP (7x7) surface mount package.
The tuning word width is 32 bits.
The RoHS status is listed as RoHS3 Compliant, but this data is unverified.
