AD7948BN Description

Short technical summary and product information.

The AD7948BN is a 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices. It utilizes an R-2R ladder architecture and provides a current-unbuffered output. The device features an 8-bit byte parallel interface (DB7-DB0) with control logic for data loading, making it suitable for microprocessor-based systems.

 

Key electrical specifications include a typical settling time of 600 ns (to 0.01% with an AD843 op amp), integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB maximum, and low power consumption of 5 mW typical at 5V supply. The DAC operates over a temperature range of -40°C to 85°C.

 

The AD7948BN is designed for battery-powered instrumentation, laptop computers, and as an upgrade for 754x series DACs in 5V designs. It requires an external voltage reference.

 

The device is offered in a 20-lead PDIP package (20-DIP, 0.300" width) with through-hole mounting. The supplier device package is 20-PDIP.
