ADC CIRCUIT INFORMATION
The ADuC7060 incorporates two independent multichannel
Σ-Δ ADCs. The primary ADC is a 24-bit, 5-channel ADC. The
auxiliary ADC is a 24-bit Σ-Δ ADC, with up to eight input
channels.
The primary ADC input has a mux and a programmable gain
amplifier on its input stage. The mux on the primary channel
can be configured as two fully differential input channels or as
four single-ended input channels.
The auxiliary ADC incorporates a buffer on its input stage.
Digital filtering is present on both ADCs, which allows

measurement of a wide dynamic range and low frequency
signals such as those in pressure sensor, temperature sensor,
weigh scale, or strain gage type applications.
The ADuC7060 auxiliary ADC can be configured as four fully
differential input channels or as eight single-ended input
channels.
Because of internal buffering, the internal channels can convert
signals directly from sensors without the need for external
signal conditioning.
