3 / 44 page  ADT7516/ADT7517/ADT7519 Rev. A | Page 3 of 44 SPECIFICATIONS Table 1. Temperature range is as follows: A version: –40°C to +120°C. VDD = 2.7 V to 5.5 V, GND = 0 V, REFIN = 2.25 V, unless otherwise noted. Parameter1 Min Typ Max Unit Conditions/Comments DAC DC PERFORMANCE2, 3 ADT7519 Resolution 8 Bits Relative Accuracy ±0.15 ±1 LSB Differential Nonlinearity ±0.02 ±0.25 LSB Guaranteed monotonic over all codes. ADT7517 Resolution 10 Bits Relative Accuracy ±0.5 ±4 LSB Differential Nonlinearity ±0.05 ±0.5 LSB Guaranteed monotonic over all codes. ADT7516 Resolution 12 Bits Relative Accuracy ±2 ±16 LSB Differential Nonlinearity ±0.02 ±0.9 LSB Guaranteed monotonic over all codes. Offset Error ±0.4 ±2 % of FSR Gain Error ±0.3 ±2 % of FSR Lower Deadband 20 65 mV Lower deadband exists only if offset error is negative. See Figure 8. Upper Deadband 60 100 mV Upper deadband exists if VREF = VDD and off-set plus gain error is positive. See Figure 9.
