MAX22007 Four-Channel Analog Output ICs

Analog Devices MAX22007 Four-Channel Analog Output ICs drive a voltage or current output on each channel. All outputs are protected to ±42V_P-P for a high-voltage supply of HVDD = 8V to 20V and HVSS = -2V to 0V. Each output channel of the MAX22007 features a 12-bit DAC with a fast settling time using a shared internal voltage reference. The device offers low-offset, high-voltage amplifiers to condition the signal from low-voltage DAC outputs to high-voltage or current outputs. If one output is miswired, all other outputs remain unaffected and function normally. For each channel, an internal comparator can be used to determine the load impedance and allows the microcontroller to intelligently select for voltage or current output mode. All outputs are kept safe by integrated current protection for functional and thermal robustness. The Analog Devices MAX22007 also includes a thermal shutdown circuit that protects the device when the junction temperature exceeds +165°C (typical).
