AD7945BNZ Description

Short technical summary and product information.

The AD7945BNZ is a 12-bit multiplying digital-to-analog converter (DAC) from Analog Devices, designed for single +5V supply operation. It features a parallel data interface for fast writes and an R-2R architecture that provides excellent linearity with integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB maximum. The output is current-unbuffered, allowing external op-amp configuration for voltage output.

 

With a typical settling time of 600 µs, this DAC is suitable for applications requiring moderate speed conversion. It operates over an industrial temperature range of -40°C to +85°C. The device uses an external voltage reference, enabling multiplying DAC functionality for variable gain or attenuation.

 

The AD7945BNZ is housed in a 20-lead DIP (0.300", 7.62mm) through-hole package (20-PDIP), making it easy to integrate into breadboard or prototype designs. It is a direct upgrade for older 7545-type DACs in 5V systems, offering improved speed and power consumption.
