... All channels are updated within 330µs after data has been loaded. Each device features an output clamp and output resis- tors for filtering. The MAX5631 features a 50Ω output impedance and is capable of driving up to 250pF of out- put capacitance. The MAX5632 features a 500Ω output impedance and is capable of driving up to 10nF of output capacitance. The MAX5633 features a 1kΩ ...

... The MAX5631/MAX5632/MAX5633 contain 32 buffered sample/hold circuits with internal hold capacitors. Internal hold capacitors minimize leakage current, dielectric absorption, feedthrough, and required board space. MAX5631/MAX5632/MAX5633 provide a very low 1mV/s droop rate. The MAX5631/MAX5632/MAX5633 include output buffers on each channel. The device contains output resistors in series with the buffer output (Figure 3) for ease of output filtering and capacitive load driving stability ...

... To disable output clamp- ing, connect clamping voltages beyond the maximum output voltage range. The MAX5631/MAX5632/MAX5633 are controlled by an SPI, QSPI, and MICROWIRE-compatible 3-wire inter- face. Serial data is clocked into the 24-bit shift register in an MSB-first format, with the 16-bit DAC data pre- ceding the 5-bit SRAM address, 2-bit control, and a fill 0 (Figure 4) ...
