(2) Use an external buffer amplifier with high-impedance input to drive any external load. (3) To ensure power supply accuracy and to account for power supply filter network loss at operating conditions, the use of the ATEST function in register config27 to check the internal power supply nodes is recommended. (4) Includes AVDD, PLLAVDD, and IOVDD 8 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Link(s): DAC34SH84 |
