(2) Analog input bandwidth is defined as the frequency at which the sampled input signal is 3 dB down on unity gain and is limited by the input switch impedance. PGA SPECIFICATIONS PARAMETER MIN TYP MAX UNIT Gain Range 0 to 18 dB Gain Step Size(1) 0.5826 dB Gain Error(2) −0.15 ±0.025 0.15 dB Control Bits Per Channel 5 Bits (1) See Table 2, PGA Gain Code. Ideal step size: 18.0618 dB / 31 = 0.5826 dB (2) Deviation from ideal. See Table 2, all gain settings. |
