AD7837AR Description

Short technical summary and product information.

The AD7837AR is a 12-bit dual digital-to-analog converter (DAC) from Analog Devices Inc. It provides two voltage-buffered outputs with a settling time of 5 µs maximum to within ±1/2 LSB. The device uses a parallel data interface and an external voltage reference, with an R-2R ladder architecture for accurate conversion.

 

Key electrical specifications include integral nonlinearity (INL) of ±1 LSB max, differential nonlinearity (DNL) of ±1 LSB max (guaranteed monotonic), zero code offset error of ±2 mV max at +25°C, and gain error of ±2 LSB max at +25°C. The DAC operates from dual supplies of ±14.25V to ±15.75V, with typical supply currents of 5 mA (IDD) and 3 mA (ISS).

 

The AD7837AR is housed in a 24-SOIC surface mount package (0.295" width, 7.50mm body width) and operates over an industrial temperature range of -40°C to +85°C. It is suitable for precision applications requiring two DAC channels in a compact footprint.
