Description
The MAX5661 provides either a current output or a voltage output. Only one output is active at any given time, regardless of the configuration. The MAX5661 voltage output operates with ±13.48V to ±15.75V supplies (VDDV, VSSV) and the current output operates with a single +13.48V to +40V supply (VDDI). A +4.75V to +5.25V digital supply (VCC) powers the rest of the internal circuitry. A buffered reference input accepts an external +4.096V reference voltage.
Update the DAC outputs using software commands or the asynchronous active-low LDAC input. An asynchronous active-low CLR input sets the DAC outputs to the value stored in the clear register or to zero. The active-low FAULT output asserts when the DAC's current output is an open circuit, the DAC's voltage output is a short circuit, or when the active-low CLR input is low.
The MAX5661 communicates through a 4-wire 10MHz SPI-/QSPI™-/MICROWIRE™-compatible serial interface. The DOUT output allows daisy chaining of multiple devices. The MAX5661 is available in a 10mm x 10mm, 64-pin, LQFP package and operates over the -40°C to +105°C temperature range.
