DAC8841FSZ

DAC8841FSZ Description

The DAC8841FSZ is an 8-bit digital-to-analog converter (DAC) from Analog Devices Inc., part of the TrimDAC® series. Designed for precision voltage output applications, this surface-mount IC features 8 channels with a voltage output range and operates with ±5V analog and digital supplies. It utilizes an SPI interface for flexible digital communication, ensuring seamless integration into microcontroller-based systems. With a settling time of 6µs and ±0.5 LSB INL/DNL (max), it delivers high accuracy for demanding analog control tasks. The device is packaged in a 24-pin SOIC tube and is classified as obsolete, though its performance remains competitive for legacy designs.

DAC8841FSZ Features

• 8-bit resolution with 8 independent DAC channels for multi-channel applications.
• SPI-compatible serial interface for simplified digital control.
• Fast settling time (6µs) ensures rapid response in dynamic systems.
• Low INL/DNL (±0.5 LSB max) for high linearity and precision.
• Single +5V supply operation (analog and digital) reduces power complexity.
• External voltage reference support for flexible output scaling.
• Surface-mount 24-SOIC package optimizes board space in compact designs.
• Industrial-grade reliability with MSL 1 (unlimited) moisture sensitivity.
