LTC2656 DAC Has 0.1 Percent Gain Error
Linear Technology has introduced the LTC2656, a 16-bit octal digital-to-analogue converter (DAC) that offers +/-4LSB INL maximum over temperature. The combination of 0.1 per cent (max) gain error and +/-2mV (max) offset error ensure that LTC2656 remains accurate near the supply rails and provides the user with a wider effective-output range. The LTC2656's precision specifications make it suitable for multichannel open- and closed-loop systems typically found in communication systems, industrial process control, automated test equipment (ATE) and programmable logic controllers. The converter integrates a precision reference that achieves 2ppm/C typical and 10ppm/C maximum temperature coefficient. By integrating the reference in its 20-pin 4 x 5mm QFN and TSSOP packages, the LTC2656 offers further space reduction for densely packed circuit boards. Operating from a single 2.7 to 5.5V supply, supply current is 375uA per DAC with the reference activated. The LTC2656 offers 8.5us se...
