The values are valid for manual mode. In burst mode, values degrade by ~1 dB. 3 Not production tested. Sample tested during initial release to ensure compliance. 4 LSB means least significant bit. With a ±2.5 V input range, 1 LSB = 305.175 µV. With a ±5 V input range, 1 LSB = 610.351 µV. With a ±10 V input range, 1 LSB = 1.220 mV. 5 Positive and negative full-scale error for the internal reference excludes reference errors. 6 Supported by simulation data.
