The C8051F350/1/2/3 include a fully-differential, 24-bit (C8051F350/1) or 16-bit (C8051F352/3) Sigma-
Delta Analog to Digital Converter (ADC) with on-chip calibration capabiliites. Two separate decimation fil-
ters can be programmed for throughputs of up to 1 kHz. An internal reference is available, or a differential
external reference can be used for ratiometric measurements. A Programmable Gain Amplifier (PGA) is
included, with eight gain settings up to 128x. The on-chip input buffers can be used to provide a high input
impedance for direct connection to sensitive transducers. An 8-bit offset DAC allows for correction of large
input offset voltages.
