The RHRDAC1612 is a very low-noise, low-frequency, radiation hardened DAC optimized to operate in a bandwidth up to 3 kHz. This DAC has a sigma-delta architecture which provides superior linearity performance and features a very good signal-to-noise ratio of 96 dB@3 kHz.
The DAC operates with a standard SPI input data which it converts into single-ended, internally-filtered voltage outputs. The SPI interface allows write and read mode implementations.
Specifically designed to optimize precision over power consumption, the RHRDAC1612 only dissipates 15 mW at 12 ksps clocking.Key Features
