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.
The supply voltage is 5V.
The AD7948BN is available in a 20-DIP (0.300", 7.62mm) package.
The operating temperature range is -40°C to 85°C.
The AD7948BN is listed as RoHS3 Compliant, but this status is unverified.
