MAX5661 19-0741 Rev 1 5/09 Single 16-Bit DAC with Current and Voltage Outputs for Industrial Analog Output Modules General Description Features 10-Bit Programmable Full-Scale Output The MAX5661 single 16-bit DAC with precision high- voltage amplifiers provides a complete solution for pro- Adjustment for Up to 25% Over Range grammable current and voltage-output applications. Programmable Voltage Output The output amplifiers swing to industry-standard levels Unipolar Range: 0 to +10.24V 25% of 10V (voltage output) or source from 0mA (or from Bipolar Range: 10.24V 25% 4mA) to 20mA (current output). The voltage output (OUTV) drives resistive loads greater than 2k and Programmable Current Output capacitive loads of up to 1.2F. Voltage-output force- Unipolar Low Range: 0 to 20.45mA sense connections compensate for series protection Unipolar High Range: 3.97mA to 20.45mA resistors and field-wiring resistance. Short-circuit pro- Flexible Analog Supplies (See Table 16) tection on the voltage output limits output current to 13.48V to 15.75V for Voltage Output 10mA (typ) sourcing or -11.5mA (typ) sinking. The cur- rent output (OUTI) drives resistive loads up to 37.5V +13.48V to +40V for Current Output (max) and inductive loads up to 1H. Force-Sense Connections (Voltage Output) The MAX5661 provides either a current output or a volt- for Differential Voltage-Output Remote Sensing age output. Only one output is active at any given time, Voltage-Output Current Limit regardless of the configuration. The MAX5661 voltage output operates with 13.48V to 15.75V supplies Dropout Detector Senses Out-of-Regulation (V , V ) and the current output operates with a DDV SSV Current Output single +13.48V to +40V supply (V ). A +4.75V to DDI CLR and LDAC Inputs for Asynchronous DAC +5.25V digital supply (V ) powers the rest of the inter- CC nal circuitry. A buffered reference input accepts an Updates external +4.096V reference voltage. CLR Input Resets Output to Programmed Value or Update the DAC outputs using software commands or Zero Code the asynchronous LDAC input. An asynchronous CLR FAULT Output Indicates Open-Circuited Current input sets the DAC outputs to the value stored in the Output, Short-Circuited Voltage Output, or Clear clear register or to zero. The FAULT output asserts when the DACs current output is an open circuit, the State DACs voltage output is a short circuit, or when the CLR Temperature Drift input is low. Voltage Output: 0.4ppm FSR/C The MAX5661 communicates through a 4-wire 10MHz Current Output: 7.9ppm FSR/C SPI-/QSPI-/MICROWIRE-compatible serial inter- Small 64-Pin LQFP Package (10mm x 10mm) face. The DOUT output allows daisy chaining of multi- ple devices. The MAX5661 is available in a 10mm x 10mm, 64-pin, LQFP package and operates over the -40C to +105C temperature range.
