EVALUATION KIT AVAILABLE MAX5138/MAX5139 Low-Power, Single, 16-/12-Bit, Buffered Voltage-Output DACs General Description Features 16-/12-Bit Resolution in a 3mm x 3mm, 16-Pin The MAX5138/MAX5139 are a family of single-channel TQFN Package pin-compatible and software-compatible 16-bit and 12- bit DACs. The MAX5138/MAX5139 are low-power, 16- Hardware-Selectable on Power-Up or Reset-to- Zero/Midscale DAC Output bit/12-bit, buffered voltage-output, high-linearity DACs. They use a precision internal reference or a precision Double-Buffered Input Registers external reference for rail-to-rail operation. The LDAC Asynchronously Updates DAC Output MAX5138/MAX5139 accept a wide +2.7V to +5.25V sup- READY Facilitates Daisy Chaining ply-voltage range to accommodate most low-power and High-Performance 10ppm/C Internal Reference low-voltage applications. These devices accept a 3-wire TM SPI-/QSPI -/MICROWIRE -/DSP-compatible serial Guaranteed Monotonic Over All Operating Conditions interface to save board space and reduce the complexi- ty of optically isolated and transformer-isolated applica- Wide +2.7V to +5.25V Supply Range tions. The digital interfaces double-buffered hardware Rail-to-Rail Buffered Output Operation and software LDAC provide simultaneous output update. Low Gain Error (Less Than 0.5% FS) and Offset The serial interface features a READY output for easy (Less Than 10mV) daisy-chaining of several MAX5138/MAX5139 devices 30MHz 3-Wire SPI-/QSPI-/MICROWIRE-/ and/or other compatible devices. The MAX5138/MAX5139 DSP-Compatible Serial Interface include a hardware input to reset the DAC outputs to CMOS-Compatible Inputs with Hysteresis zero or midscale upon power-up or reset, providing additional safety for applications that drive valves or Low Power Consumption (I = 2A max) SHDN other transducers that need to be off during power-up. The high linearity of the DACs makes these devices ideal Ordering Information for precision control and instrumentation applications. The MAX5138/MAX5139 are available in an ultra-small RESOLUTION PART PIN-PACKAGE (3mm x 3mm), 16-pin TQFN package and are specified (BITS) over the -40C to +105C extended industrial tempera- MAX5138BGTE+ 16 TQFN-EP* 16 ture range.
