DAC312HSZ-REEL

Digital To Analog Converters Overview

The DAC312HSZ-REEL is a 12-bit high-speed multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a 20-SOIC surface-mount package and operates with analog supply voltages ranging from +4.5 V to +18 V and -10.8 V to -18 V, alongside a digital supply range of up to 20 V. The device delivers a typical settling time of 250 ns to ±1/2 LSB and provides differential current outputs capable of 0 to 4 mA. Key electrical specifications include a maximum integral nonlinearity of ±0.05% FS and differential nonlinearity of ±1 LSB. It consumes 225 mW at standard supply levels and supports direct interface with TTL, CMOS, ECL, and PMOS/NMOS logic families.

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix (e.g., H for industrial temperature range) against project requirements, as the base model number covers multiple performance tiers. Confirm that the REEL suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the selected variant meets the required operating temperature range and linearity specifications defined in the datasheet.

Digital To Analog Converters Selection Notes

Select the DAC312HSZ-REEL when a 12-bit resolution with fast 250 ns settling time is required for multiplying applications. Ensure the system design accommodates the dual power supply rails (+4.5V to +18V and -10.8V to -18V). Verify that the load resistance allows for proper output compliance within the specified -5 V to +10 V range. Consider the 225 mW power dissipation for thermal management in the 20-SOIC package.

Digital To Analog Converters Part Context

The DAC312 series utilizes a hybrid architecture combining a 9-bit master D/A converter with a 3-bit segment generator. This design ensures uniform step sizes and guarantees monotonicity without the stringent matching requirements of a pure R-2R ladder. The component follows the industry-standard AM6012 pinout, facilitating compatibility with legacy designs and simplifying board layout for engineers familiar with this form factor.
