1. CHARACTERISTICS & SPECIFICATIONS
ANALOG CHARACTERISTICS Notes:T
A = -40 C to +85 C; VA+ = 5V or 2.5V ± 5%; VA - = 0V or
-2.5V ± 5%; VD = 5V or 3.3V ± 5%; DGND = 0V; MCLK = 2.048 MHz; [(VREF+) - (VREF-)] = 2.5V;
Devices are connected as shown in Figure 3, the System Connection Diagram.
Notes: 1. Dynamic Range defined as 20 log [ (RMS full scale) / (RMS idle noise) ]
2. Tested with full-scale input signal of 31.25 Hz; OWR = 1000 SPS; OFST = 1.
3. Specification is for the parameter over the specified temperature range for the CS5371/72 devices only
and does not include the effects of external components.
4. Specifications are guaranteed by design and/or characterization.
5. The offset after calibration specification applies to the effective offset voltage for a full-scale input to the
CS5371/72 modulator, but is measured from the output digital codes from the digital filter.
6. The CS5371/72 offset calibration is performed digitally and includes the full-scale range.
