ANALOG DEVICES LTC1821-1BCGW#PBF Digital to Analogue Converter, 16 bit, Parallel, ± 4.5V to ± 16.5V, WSSOP, 36 Pins

LTC1821-1BCGW#PBF is a parallel input 16bit multiplying voltage output DAC that operates from analogue supply voltages of ±5V up to ±15V. INL and DNL are accurate to 1LSB over the industrial temperature range in both unipolar 0V to 10V and bipolar ±10V modes. Precise 16bit bipolar ±10V outputs are achieved with on-chip 4-quadrant multiplication resistors. This device includes an internal deglitcher circuit that reduces the glitch impulse to less than 2nV�s (typ). The LTC1821 settles to 1LBS in 2µs with a full-scale 10V step. The combination of fast, precise settling and ultra-low glitch makes the LTC1821 ideal for precision industrial control applications. Applications include process control and industrial automation, precision instrumentation, direct digital waveform generation, software-controlled gain adjustment, automatic test equipment.
