NOTES: (1) Digital inputs are TTL, LSTTL, 54/74HC and 54/74HTC compatible over the specification temperature range. (2) FSR means Full-Scale Range. For example, for ±10V output, FSR = 20V. (3) ±0.0015% of FSR is equal to 1LSB in 16-bit resolution. ±0.003% of FSR is equal to 1LSB in 15-bit resolution. ±0.006% of FSR is equal to 1LSB in 14-bit resolution. (4) Error at input code 0000H (BTC). (5) Adjustable to zero with external trim potentiometer. Adjusting the gain potentiometer rotates the transfer function around the bipolar zero point. (6) Maximum represents the 3 σ limit. Not tested for this parameter. (7) The bipolar worst- case code change is FFFFH to 0000H (BTC). (8) Minimum supply voltage for ±10V output swing is approximately ±13V. Output swing for ±12V supplies is at least ±9V. |
