CS4373 Datasheet, PDF (4/20 Pages) Cirrus Logic – Low-power, High-performance Delta-Sigma Test DAC

CS4373
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 T_A = 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.
