Detailed Description

Quad 16-bit voltage-output DAC with parallel data interface and internal reference, R-2R architecture, buffered single-ended outputs. Surface-mount 64-LQFP package (10 x 10 mm). Industrial temperature range -40°C to 85°C. RoHS3 compliant. Ideal for precise, multi-channel analog control and instrumentation.

Key Features

Resolution: 16-bit per channel

Channels: 4 independent DACs

Interface: Parallel data bus for fast updates

Architecture: R-2R for predictable accuracy

Output type: Buffered voltage outputs

Reference: Internal reference for stable performance

Analog supply: ±5 V

Digital supply: 5 V logic

INL/DNL: ±2 LSB INL, ±1 LSB DNL (typical class values)

Settling time: 15 s listed; consult datasheet for typical µs-level settling

Differential outputs: No (single-ended outputs)

Package: 64-LQFP (10 x 10 mm), tape and reel

Operating temperature: -40°C to +85°C

Compliance: RoHS3 compliant

Key Advantages

High precision 16-bit resolution across four channels reduces error and improves control accuracy

Parallel interface enables high throughput and low update latency compared to serial-only DACs

Internal reference simplifies design and reduces external component count

Buffered outputs provide low impedance drive and stable voltage outputs

R-2R architecture delivers monotonic behavior and consistent linearity over temperature and supply

Industrial temperature range ensures reliable operation in harsh environments

Compact 64-LQFP package integrates four DACs to save board space and BOM cost

RoHS3 compliance supports modern environmental requirements

Packaging

Shipping packaging: Tape & Reel (TR) for automated assembly and high-volume production

Device package: 64-LQFP, 10 x 10 mm body size, quad flat package with leads on all four sides

Material and finish: Epoxy molding compound with copper leadframe; matte-tin lead finish (typical for LQFP)

Pin configuration: 64 leads including parallel data bus pins, control pins (enable/write), power pins (analog ±5 V, digital 5 V, grounds), reference pins, and four buffered DAC output pins

Lead pitch: Approximately 0.5 mm (typical for 64-LQFP)

Thermal characteristics: Typical LQFP thermal performance with board-dependent θJA; use good copper planes for heat spreading and stability

Electrical properties: 16-bit R-2R DAC cores, internal reference, buffered single-ended outputs, logic-compatible 5 V digital domain, ±5 V analog domain
