DATASHEET
SX8722
High gain acquisition for sensor interface
The core of the zooming section is made of three differential programmable amplifiers (PGA). After selection of a
combination of input and reference signals VIN and VREF, the input voltage is modulated and amplified through stages 1 to 3.
Fine gain programming up to 1'000V/V is possible. In addition, the last two stages provide programmable offset. Each
amplifier can be bypassed if needed.
The output of the PGA stages is directly fed to the analog-to-digital converter (ADC), which converts the signal VIN,ADC into
digital.
Like most ADCs intended for instrumentation or sensing applications, the ZoomingADC is an over-sampled converter (See
Note1). The ADC is a so-called incremental converter with bipolar operation (the ADC accepts both positive and negative
input voltages). In first approximation, the ADC output result relative to full-scale (FS) delivers the quantity:
in two's complement (see Section 12.8.7 for details). The output code OUTADC is -FS/2 to +FS/2 for VIN,ADC, -VREF/2 to
+VREF/2 respectively. As will be shown in section 0, VIN,ADC is related to input voltage VIN by the relationship:
where GDTOT is the total PGA gain, and GDoffTOT is the total PGA offset.
Note:
Over-sampled converters are operated with a sampling frequency fS much higher than the input signal's Nyquist rate (typically fS
is 20-1'000 times the input signal bandwidth). The sampling frequency to throughput ratio is large (typically 10-500). These
converters include digital decimation filtering. They are mainly used for high resolution, and/or low-to-medium speed applications.
