Data interface parallel for fast, low-latency updates

Architecture R-2R for predictable linearity

Reference internal and external selectable for flexibility

INL/DNL up to ±4 LSB and ±2 LSB (Max) for accuracy

Analog supply wide range ±11.4 V to ±15.75 V and single negative -4.75 V to -15.75 V

Digital supply 5 V logic compatible

Operating temperature -40°C to +85°C

Differential output no (single-ended output)

D/A converters 1 channel

Base product number DAC7742

ROHS3 compliant

Key Advantages

High resolution enables fine control in precision systems

Buffered output simplifies load driving and reduces external components

Flexible reference options minimize BOM or enable higher accuracy, as needed

Parallel interface offers deterministic timing and quick updates for control loops

Industrial temperature grade supports harsh environments

Wide analog supply supports large output ranges for bipolar and unipolar systems

48-LQFP package suits high-density SMT designs and automated manufacturing

Packaging

Type 48-LQFP low-profile quad flat package, body size 7x7 mm

Material molded epoxy package with copper leadframe, lead-free finish (ROHS3)

Pin count 48 leads, typical fine-pitch LQFP

Pin configuration includes parallel data bus pins, control pins (e.g., write, load), reference pins (internal/external), analog supplies, digital supply, ground, and buffered voltage output

Supplier device package 48-LQFP (7x7)

Tape & Reel option DAC7742YB/2K for automated pick-and-place

Thermal characteristics depend on PCB layout and copper area; use good thermal design and decoupling near supply pins

Electrical properties include 5 V digital domain, high-voltage analog domain, ESD protection per manufacturer standards, and buffered single-ended output
