C8051F350/1/2/3
1.4.
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 2.5 V reference is available, or a differ-
ential external reference can be used for ratiometric measurements. A Programmable Gain Amplifier
(PGA) is included, with eight gain settings up to 128x. An analog front-end multiplexer connects the differ-
ential inputs to eight external pins, the internal temperature sensor, or AGND. The on-chip input buffers
can be used to provide a high input impedance for direct connection to sensitive transducers. An 8-bit off-
set DAC allows for correction of large input offset voltages.
