MAX5631/MAX5632/ MAX5633 16-Bit DACs with 32-Channel Sample-and-Hold Outputs General Description Features The MAX5631/MAX5632/MAX5633 are 16-bit digital-to- Integrated 16-Bit DAC and 32-Channel SHA with analog converters (DACs) with 32 sample-and-hold SRAM and Sequencer (SHA) outputs for applications where a high number of 32 Voltage Outputs programmable voltages are required. These devices 0.005% Output Linearity include a clock oscillator and a sequencer that updates 200V Output Resolution the DAC with codes from an internal SRAM. No external Flexible Output Voltage Range components are required to set offset and gain. Remote Ground Sensing The MAX5631/MAX5632/MAX5633 feature a -4.5V to Fast Sequential Loading: 1.3s per Register +9.2V output voltage range. Other features include a Burst and Immediate Mode Addressing 200V/step resolution, with output linearity error, typi- No External Components Required for Setting cally 0.005% of full-scale range (FSR). The 100kHz Gain and Offset refresh-rate updates each SHA every 320s, resulting Integrated Output Clamp Diodes in negligible output droop. Remote ground sensing Three Output Impedance Options: allows the outputs to be referenced to the local ground MAX5631 (50), MAX5632 (500), and of a separate device. MAX5633 (1k) These devices are controlled through a 20MHz Ordering Information SPI/QSPI/MICROWIRE -compatible 3-wire serial interface.
