MAX22007 Four-Channel 12-Bit Configurable Analog Output with Integrated Voltage Reference General Description Benefits and Features The MAX22007 is a software-configurable four-channel Configurable Outputs analog output device that drives a voltage or current out- Each Output Individually Configurable put on each channel. All outputs are protected to 42V P-P Internal Comparator to Allow Calculating Load for high-voltage supply of HVDD = 8V to 20V and HVSS = Impedance for Voltage-Mode or Current-Mode -2V to 0V. Voltage Mode is 0V to 10.5V Linear Range with Each output channel of the MAX22007 features a 12-bit 12.5V Overrange for Loads from 1k to 1M DAC with fast settling time using a shared internal voltage Current Mode is 0mA to 21mA Linear Range with reference. The device offers low-offset, high-voltage am- 25mA Overrange for Loads from 0 to 750 plifiers to condition the signal from low-voltage DAC out- System Accuracy puts to high-voltage or current outputs. If one output is V/I Output Resolution is 12-Bits miswired, all other outputs remain unaffected and function Factory Calibrated for Gain and Offset Error within normally. For each channel, an internal comparator can 0.2% at +25C be used to determine the load impedance and allows the V/I Total Unadjusted Error Less Than 1% from microcontroller to intelligently select for voltage or cur- -40C to +85C rent output mode. All outputs are kept safe by integrated Robust with Integrated Diagnostics current protection for functional and thermal robustness. 42V Protection for Output Drivers P-P The MAX22007 also includes a thermal shutdown circuit 1kV Surge Protection with 4.99k Series that protects the device when the junction temperature ex- Resistors at Input Pins ceeds 165C (typ). 2.5kV HBM ESD Protection on All Pins The MAX22007 communicates with a microcontroller us- Outputs have Short-Circuit and Overvoltage ing a SPI interface at clock rates up to 30MHz with an Protection with External Diodes optional eight-bit CRC for improved data integrity. Eight Thermal Monitoring and Shutdown Protection GPIOs can be used to interface and control other re- Simple and Low-Cost Interface sources in the application circuit. The MAX22007 operates Up to 30MHz SPI Serial Interface with Optional from a 2.7V to 5.5V V low-voltage supply and an 8V DD 8-Bit CRC to 24V HVDD positive high-voltage supply. The negative Daisy-Chain Mode to Reduce System Cost voltage supply HVSS can be set between -2V and 0V. V = 2.7V to 5.5V for Easy Interface to the DD The MAX22007 is available in an 8mm x 8mm 56-pin Microcontroller TQFN package and operates over the -40C to +85C High Voltage Output Supplies: temperature range with 2.5kV HBM ESD protection on all HVDD: +8V to +24V pins.
