ANALOG-TO-DIGITAL CONVERTER WITH SERIAL INTERFACE AND REFERENCE
• 600-kHz Sample Rate • Medical Instruments
• Optical Networking• ± 2 LSB Typ, ± 4 LSB Max INL
• Transducer Interface• 18-Bit NMC Ensured Over Temperature
• High Accuracy Data Acquisition Systems• SINAD 91 dB, SFDR 119 dB at f i = 1 kHz
• Magnetometers• High-Speed Serial Interface up to 40 MHz
• Onboard Reference Buffer
• Onboard 4.096-V Reference
The ADS8380 is a high performance 18-bit, 600-kHz• Pseudo-Differential Input, 0 V to 4.2 V
