The NSAD1148/NSAD1147/NSAD1146 are low power, low noise, 16-bit, delta-sigma(Δ-Σ), analog-to-digital converters (ADCs). The device contains a cpacitive programmable gain amplifier (cpacitive PGA), with gains of 1, 2, 4, 8, 16, 32, 64 and 128, which allows to achieve rail-to-rail common-mode input range for all gains. These ADCs feature configurable digital filters with low
