Note that the output ranges 3.92 mA to 20.4 mA, 0 mA to 20.4 mA, and 0 mA to 24.5 mA are all designed to be trimmed by the customer to precisely match the 4 mA to 20 mA, 0 mA to 20 mA, and 0 mA to 24 mA ranges. The 1.86% FSR output error measurement in the 0 mA to 20.4 mA range includes the gain error, which is easily removed by customer calibration. There is a lower dead band about 10 mV referenced to GND. All the linearity test results were calculated using a reduced code range of 256 to 65,535. For 3.92 mA to 20.4 mA, 0 mA to 20.4 mA, and 0 mA to 24.5 mA, the lower dead band is larger than other standard ranges, and the measured code range is from 1000 to 65,535. COMMON VARIATIONS The AD5685R (14 bits) and the AD5684R (12 bits) are pin- compatible with the AD5686R for applications not requiring 16-bit resolution. For applications that require channel-to-channel isolation, single DACs, such as the AD5660 (16 bits), the AD5640 (14 bits), and the AD5620 (12 bits), are good choices. For single-channel applications, see the CN-0202, CN-0203, and CN-0204 circuit notes for more details. For multichannel applications, the AD5623R (12-bits), AD5643R (14-bits), and AD5663R (16-bits) are dual nanoDACs, and the AD5624R (12-bits), AD5644R (14-bits), and AD5664R (16-bits) are quad nanoDACs. The AD5628/ AD5648/AD5668 are octal 12-/14-/16-bit SPI voltage output denseDACs with 5 ppm/°C on-chip references. The AD5750 and AD5750-1 drivers are pin-compatible with the AD5750-2. The AD5750 can accept 0 V to 4.096 V input with a 4.096 V reference. The AD5750-1 can accept a 0 V to 2.5 V input with a 1.25 V reference. The AD5751 is a unipolar analog output driver and can supply a 40 V output using a 50 V AVDD supply.
