RH-DAC121K1
Overview
The RH-DAC121K1 is a radiation-hardened 12-bit digital-to-analog converter designed for high-reliability aerospace and defense applications. It operates over a wide voltage range of 2.3V to 3.6V and features a rail-to-rail voltage output with a fast 13us settling time. This device is housed in a hermetic 10-pin ceramic FlatPack, ensuring performance in extreme environments from -55C to 125C.
Why Choose This Part
This DAC features an internal voltage reference and ensured monotonicity, which simplifies design by reducing external component count. Its extremely low power-down current of 0.5uA and power-on-reset to zero volts make it ideal for power-sensitive and safety-critical aerospace systems.
Applications
Key Specifications
Getting Started
Interface with the device using the standard SPI protocol for data transfer and utilize the SYNC interrupt facility for precise conversion timing. Engineers should follow high-reliability PCB layout guidelines for ceramic FlatPack packages, ensuring proper thermal and mechanical mounting for high-vibration environments.
