AD7628KR

The AD7628KR is a monolithic dual 8-bit digital-to-analog converter (DAC) from Analog Devices, designed for applications requiring excellent DAC-to-DAC matching. Fabricated on a single chip, it ensures precise tracking between its two DAC channels. This device features separate on-chip latches for each DAC, facilitating straightforward microprocessor interfacing. Data is transferred via a common 8-bit TTL/CMOS compatible input port, with a dedicated DAC A/DAC B control input to select the target latch.

Operating from a +12 V to +15 V power supply, the AD7628KR exhibits low power dissipation of just 20 mW. It supports four-quadrant multiplication characteristics, with individual reference inputs and feedback resistors for each DAC. Key electrical specifications include 8-bit resolution, ±1/2 LSB relative accuracy, and ±1 LSB differential nonlinearity over the operating temperature range. The device is bus compatible with most 8-bit microprocessors.

Available in a compact 20-pin DIP package, the AD7628KR is suitable for space-constrained designs. Its TTL-compatible digital inputs ensure easy integration into existing systems. Applications include disk drives, programmable filters, X-Y graphics, and gain/attenuation circuits.
