The AD1940YSTZ is a high-performance audio digital signal processor (DSP) from Analog Devices Inc., part of the SigmaDSP family. It features 28-bit resolution and a maximum sampling rate of 192 kHz, making it suitable for demanding audio processing tasks. The device includes 4 audio channels and communicates via a SPI data interface. It operates from a single supply voltage in the range of 2.25V to 2.75V, and is specified for an industrial temperature range of -40°C to +125°C.
The DSP core incorporates a 28-bit x 28-bit multiplier with a 56-bit accumulator, and fully programmable program RAM for custom algorithm downloads. Parameter RAM allows control of up to 1,024 parameters, and the serial data port supports I2S-compatible, left-justified, and right-justified modes. The device also includes an on-chip voltage regulator for compatibility with 3.3V and 5V systems.
The AD1940YSTZ is supplied in a 48-LQFP (7x7 mm) surface mount package. This package is suitable for automated assembly and is widely used in space-constrained audio applications. The device is ideal for automotive sound systems, home theater systems, digital televisions, and multichannel audio equipment.
Designers should note the SPI control interface for programming and parameter updates. The device supports a programmable low-power mode and fast start-up from power-on or reset. For procurement, verify RoHS and REACH compliance as current data is unverified.
