The MAX5170 is a serial-input/voltage-output, 14 bit digital-to-analogue converter (DAC) featuring proprietary on-chip circuitry that eliminates power-up glitch. Unlike other DACs that generate an undesirable voltage glitch of 2 V to 3 V at the output during power-up, the MAX5170 keeps the otuput voltage virtually 'glitch-free' (to less than 5 m V). This device also guarantees monotonicity with +/- 1 LSB max differential nonlinearity and +/- 1 LSB integral nonlinearity at 14 bit resolution.
These low-power devices operate from a single +5 V supply and draw a maximum of only 280 micro amps of supply current, which reduces to 1 micro amp in power-down mode. In addition, a power-up reset feature allows for a user-selectable initial output state of either zero or midscale. The user-accessible inverting input and output of the amplifier allow specific gain configurations, remote sensing, and high-output-drive capability for a wide range of force/sense applications. The buffered output is capable of driving 5 kilo ohms/100 pF or 4 - 20 mA loads. For more information see page 18.
