AD7528LR

The AD7528LR from Analog Devices is a monolithic dual 8-bit digital-to-analog converter designed for applications requiring precise digital control. It features two matched DACs on a single chip, offering excellent DAC-to-DAC matching crucial for stereo audio circuits and X-Y graphics.

This device operates from a wide voltage range of +5 V to +15 V and is compatible with TTL/CMOS logic. It boasts an 8-bit resolution, providing 256 distinct output levels. The R-2R architecture ensures reliable performance, with a settling time of 400ns. Integral Non-Linearity (INL) is specified at ±0.5 LSB typical and ±1 LSB maximum, while Differential Non-Linearity (DNL) is ±0.5 LSB typical and ±1 LSB maximum, ensuring good accuracy.

The AD7528LR includes on-chip latches for each DAC, simplifying microprocessor interfacing. Data is transferred via a common 8-bit TTL/CMOS compatible input port. The device is bus compatible with most 8-bit microprocessors. It supports four-quadrant multiplication, allowing for versatile signal processing.

Packaged in a 20-SOIC surface mount package, the AD7528LR is suitable for various electronic designs. Its operating temperature range is -40°C to +85°C, making it robust for different environments. Applications include digital control of gain/attenuation, filter parameters, and stereo audio circuits.
