Description

The LTC1821 is a parallel input 16-bit multiplying voltage output DAC that operates from analog 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 16-bit bipolar ±10V outputs are achieved with on-chip 4-quadrant multiplication resistors. The LTC1821 is available in a 36-lead SSOP package and is specified over the industrial temperature range.The 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 make the LTC1821 ideal for precision industrial control applications.The asynchronousCLRpin resets the LTC1821 to zero scale and resets the LTC1821-1 to midscale.ApplicationsPrecision InstrumentationProcess Control and Industrial AutomationDirect Digital Waveform GenerationSoftware-Controlled Gain AdjustmentAutomatic Test Equipment
