Product Details
The MAX5631/MAX5632/MAX5633 are 16-bit digital-to-analog converters (DACs) with 32 sample-and-hold (SHA) outputs for applications where a high number of programmable voltages are required. These devices include a clock oscillator and a sequencer that updates the DAC with codes from an internal SRAM. No external components are required to set offset and gain.
The MAX5631/MAX5632/MAX5633 feature a -4.5V to +9.2V output voltage range. Other features include a 200µV/step resolution, with output linearity error, typically 0.005% of full-scale range (FSR). The 100kHz refresh-rate updates each SHA every 320µs, resulting in negligible output droop. Remote ground sensing allows the outputs to be referenced to the local ground of a separate device.
These devices are controlled through a 20MHz SPI/QSPI™/MICROWIRE®-compatible 3-wire serial interface. Immediate Update Mode allows any channel's output to be updated within 20µs. Burst Mode allows multiple values to be loaded into memory in a single, high-speed data burst. All channels are updated within 330µs after data has been loaded.
Each device features an output clamp and output resistors for filtering. The MAX5631 features a 50Ω output impedance and is capable of driving up to 250pF of output capacitance. The MAX5632 features a 500Ω output impedance and is capable of driving up to 10nF of output capacitance. The MAX5633 features a 1kΩ output impedance and is capable of driving up to 10nF of output capacitance.
The MAX5631/MAX5632/MAX5633 are available in 12mm x 12mm, 64-pin TQFP, and 10mm x 10mm, 68-pin thin QFN packages.
