MAX15500/MAX15501 Industrial Analog Current/ Voltage-Output Conditioners General Description Benefits and Features Supply Voltage Up to 32.5V The MAX15500/MAX15501 analog output conditioners Output Protected Up to 35V provide a programmable current up to 24mA, or a volt- Programmable Output (Plus Overrange) age up to 12V proportional to a control voltage signal. 10V The control voltage is typically supplied by an external 0 to 10V DAC with an output voltage range of 0 to 4.096V for the 0 to 5V MAX15500 and 0 to 2.5V for the MAX15501. The output 20mA current and voltage are selectable as either unipolar or 0 to 20mA bipolar. In the unipolar configuration, a control voltage 4 to 20mA Current Output Drives 0 to 1k of 5% full-scale (FS) produces a nominal output of 0A or 0V to achieve underrange capability. A control voltage Voltage Output Drives Loads Down to 1k of 100%FS produces one of two programmable levels HART Compliant (105%FS or 120%FS) to achieve overrange capability. 2ppm Gain Error Drift Over Temperature The outputs of the MAX15500/MAX15501 are protected SPI Interface, with Daisy-Chain Capability against overcurrent conditions and a short to ground or Supports +4.096V (MAX15500) or +2.5V supply voltages up to 35V. The devices also monitor for (MAX15501) Full-Scale Input Signals overtemperature and supply brownout conditions. The Extensive Error Reporting supply brownout threshold is programmable. Short-Circuit and Overcurrent Protection Open-Circuit Detection The MAX15500/MAX15501 are programmed through an Brownout Detection SPI interface capable of daisy-chained operation. The Overtemperature Protection MAX15500/MAX15501 provide extensive error reporting Fast, 40s Settling Time through the SPI interface and an additional open-drain interrupt output. The devices include an analog output to monitor load conditions. Simplified Block Diagram The MAX15500/MAX15501 operate over the -40C to +105C temperature range. The devices are available in DVDD AVDD AVDDO a 32-pin, 5mm x 5mm TQFN package.
