1. CHARACTERISTICS & SPECIFICATIONS

• Min / Max characteristics and specifications are guaranteed over all Operating Conditions.

• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25°C.

• DGND = 0 V. All voltages with respect to 0 V.

• Devices are connected as shown in Figure 4 on page 8 unless otherwise noted.

• Tests performed using the TBS bitstream at TBSGAIN = 0x4B8F2, unless otherwise noted.
