MAX5137GTG+

The MAX5137GTG+ is a pin/software compatible, 12bit, voltage output DAC in 24 pin TQFN package. It is a low power, dual 12bit, buffered voltage-output, high-linearity DAC. This device accepts a wide +2.7V to +5.25V supply voltage range to accommodate most low power and low voltage applications. It also accept a 3-wire SPI/QSPI/MICROWIRE/DSP compatible serial interface to save board space and reduce the complexity of optically isolated and transformer isolated applications. The digital interface's double buffered hardware and software active-low LDAC provide simultaneous output updates. Applications include automatic test equipment, automatic tuning, communication systems, data acquisition, gain and offset adjustment, portable instrumentation, power amplifier Control, process control and servo loops, programmable voltage and current sources.

• Hardware selectable to zero/midscale DAC output on power-up or reset
• Uses a precision internal reference or a precision external reference for rail to rail operation
• Double buffered input registers, 1.5mA supply current, -40°C to 105°C operating temperature range
• High performance 10ppm/°C internal reference, 1.25V/μs voltage output slew rate
• Low gain error less than ±0.5%FS and offset less than ±10mV
• CMOS compatible inputs with hysteresis
• Low power consumption of ISHDN = 2μA max
• Integral nonlinearity of +0.25LSB (VREFI = 5V, VAVDD = 5.25V), differential nonlinearity of +1LSB
• ±1mV offset error, ±0.2% of FS gain error
• Active-low READY facilitates daisy chaining
